Congenital Malformations of the Female Reproductive System

Overview

Definition

Congenital Congenital Chorioretinitis malformations of the female reproductive system are any congenital Congenital Chorioretinitis anomalies that affect the ovaries Ovaries Ovaries are the paired gonads of the female reproductive system that contain haploid gametes known as oocytes. The ovaries are located intraperitoneally in the pelvis, just posterior to the broad ligament, and are connected to the pelvic sidewall and to the uterus by ligaments. These organs function to secrete hormones (estrogen and progesterone) and to produce the female germ cells (oocytes). Ovaries: Anatomy, fallopian tubes Fallopian tubes The uterus, cervix, and fallopian tubes are part of the internal female reproductive system. The fallopian tubes receive an ovum after ovulation and help move it and/or a fertilized embryo toward the uterus via ciliated cells lining the tubes and peristaltic movements of its smooth muscle. Uterus, Cervix, and Fallopian Tubes: Anatomy, uterus Uterus The uterus, cervix, and fallopian tubes are part of the internal female reproductive system. The uterus has a thick wall made of smooth muscle (the myometrium) and an inner mucosal layer (the endometrium). The most inferior portion of the uterus is the cervix, which connects the uterine cavity to the vagina. Uterus, Cervix, and Fallopian Tubes: Anatomy, cervix Cervix The uterus, cervix, and fallopian tubes are part of the internal female reproductive system. The most inferior portion of the uterus is the cervix, which connects the uterine cavity to the vagina. Externally, the cervix is lined by stratified squamous cells; however, the cervical canal is lined by columnar epithelium. Uterus, Cervix, and Fallopian Tubes: Anatomy, hymen Hymen A thin fold of mucous membrane situated at the orifice of the vagina. Vagina, Vulva, and Pelvic Floor: Anatomy, and/or vulva Vulva The vulva is the external genitalia of the female and includes the mons pubis, labia majora, labia minora, clitoris, vestibule, vestibular bulb, and greater vestibular glands. Vagina, Vulva, and Pelvic Floor: Anatomy. Any of these anomalies can affect the normal reproductive and sexual functions of affected women.

Epidemiology

• Prevalence Prevalence The total number of cases of a given disease in a specified population at a designated time. It is differentiated from incidence, which refers to the number of new cases in the population at a given time. Measures of Disease Frequency of congenital Congenital Chorioretinitis uterine anomalies (CUAs):
  • 5.5% in unselected populations
  • 8% in infertile patients Patients Individuals participating in the health care system for the purpose of receiving therapeutic, diagnostic, or preventive procedures. Clinician–Patient Relationship
  • 12% in patients Patients Individuals participating in the health care system for the purpose of receiving therapeutic, diagnostic, or preventive procedures. Clinician–Patient Relationship with a history of miscarriage Miscarriage Spontaneous abortion, also known as miscarriage, is the loss of a pregnancy before 20 weeks’ gestation. However, the layperson use of the term “abortion” is often intended to refer to induced termination of a pregnancy, whereas “miscarriage” is preferred for spontaneous loss. Spontaneous Abortion
  • 25% in patients Patients Individuals participating in the health care system for the purpose of receiving therapeutic, diagnostic, or preventive procedures. Clinician–Patient Relationship with a history of infertility Infertility Infertility is the inability to conceive in the context of regular intercourse. The most common causes of infertility in women are related to ovulatory dysfunction or tubal obstruction, whereas, in men, abnormal sperm is a common cause. Infertility and miscarriage Miscarriage Spontaneous abortion, also known as miscarriage, is the loss of a pregnancy before 20 weeks’ gestation. However, the layperson use of the term “abortion” is often intended to refer to induced termination of a pregnancy, whereas “miscarriage” is preferred for spontaneous loss. Spontaneous Abortion
• Previously, there was an increased incidence Incidence The number of new cases of a given disease during a given period in a specified population. It also is used for the rate at which new events occur in a defined population. It is differentiated from prevalence, which refers to all cases in the population at a given time. Measures of Disease Frequency of CUAs in women who were exposed in utero to the drug diethylstilbestrol Diethylstilbestrol A synthetic nonsteroidal estrogen used in the treatment of menopausal and postmenopausal disorders.

Classification

The types of congenital Congenital Chorioretinitis malformations can be classified on the basis of the affected organs. Note, true congenital Congenital Chorioretinitis malformations of the vulva Vulva The vulva is the external genitalia of the female and includes the mons pubis, labia majora, labia minora, clitoris, vestibule, vestibular bulb, and greater vestibular glands. Vagina, Vulva, and Pelvic Floor: Anatomy are rare; an enlarged clitoris Clitoris An erectile structure homologous with the penis, situated beneath the anterior labial commissure, partially hidden between the anterior ends of the labia minora. Vagina, Vulva, and Pelvic Floor: Anatomy or ambiguous external genitalia is typically considered a disorder of sexual development due to testosterone Testosterone A potent androgenic steroid and major product secreted by the leydig cells of the testis. Its production is stimulated by luteinizing hormone from the pituitary gland. In turn, testosterone exerts feedback control of the pituitary LH and FSH secretion. Depending on the tissues, testosterone can be further converted to dihydrotestosterone or estradiol. Androgens and Antiandrogens exposure.

Anatomy and Embryology

Anatomy

The female reproductive system is divided into external genitalia and internal genitalia. The internal genitalia are located in the true pelvis Pelvis The pelvis consists of the bony pelvic girdle, the muscular and ligamentous pelvic floor, and the pelvic cavity, which contains viscera, vessels, and multiple nerves and muscles. The pelvic girdle, composed of 2 “hip” bones and the sacrum, is a ring-like bony structure of the axial skeleton that links the vertebral column with the lower extremities. Pelvis: Anatomy and the external genitalia are present outside the true pelvis Pelvis The pelvis consists of the bony pelvic girdle, the muscular and ligamentous pelvic floor, and the pelvic cavity, which contains viscera, vessels, and multiple nerves and muscles.

General diagnosis and management principles

• Imaging:
  • Ultrasonography: Diagnosis of any ovarian abnormality is best made by pelvic ultrasound (1st test).
  • MRI may contribute additional information.
• Karyotype should be obtained.
• Laboratory ( screening Screening Preoperative Care tests for amenorrhea):
  • Follicle-stimulating hormone ( FSH FSH A major gonadotropin secreted by the adenohypophysis. Follicle-stimulating hormone stimulates gametogenesis and the supporting cells such as the ovarian granulosa cells, the testicular sertoli cells, and leydig cells. Fsh consists of two noncovalently linked subunits, alpha and beta. Within a species, the alpha subunit is common in the three pituitary glycoprotein hormones (TSH, LH, and FSH), but the beta subunit is unique and confers its biological specificity.

Clinical presentation

The clinical presentation of anomalies depends on the underlying malformations:

• Due to abnormal uterine walls (e.g., poorly vascularized uterine septum) and/or cavity shape:
  • Recurrent pregnancy Pregnancy The status during which female mammals carry their developing young (embryos or fetuses) in utero before birth, beginning from fertilization to birth. Pregnancy: Diagnosis, Physiology, and Care loss
  • Infertility Infertility Infertility is the inability to conceive in the context of regular intercourse. The most common causes of infertility in women are related to ovulatory dysfunction or tubal obstruction, whereas, in men, abnormal sperm is a common cause. Infertility
  • Preterm delivery
  • Breech presentation Breech presentation A malpresentation of the fetus at near term or during obstetric labor with the fetal cephalic pole in the fundus of the uterus.

Pregnancy: Diagnosis, Physiology, and Care loss should have pelvic imaging, which is how CUAs are typically diagnosed. Methods include:

• Pelvic ultrasonography:
  • 1st-line test for imaging the uterus Uterus The uterus, cervix, and fallopian tubes are part of the internal female reproductive system. The uterus has a thick wall made of smooth muscle (the myometrium) and an inner mucosal layer (the endometrium). The most inferior portion of the uterus is the cervix, which connects the uterine cavity to the vagina. Uterus, Cervix, and Fallopian Tubes: Anatomy, cervix Cervix The uterus, cervix, and fallopian tubes are part of the internal female reproductive system. The most inferior portion of the uterus is the cervix, which connects the uterine cavity to the vagina. Externally, the cervix is lined by stratified squamous cells; however, the cervical canal is lined by columnar epithelium. Uterus, Cervix, and Fallopian Tubes: Anatomy, and ovaries Ovaries Ovaries are the paired gonads of the female reproductive system that contain haploid gametes known as oocytes. The ovaries are located intraperitoneally in the pelvis, just posterior to the broad ligament, and are connected to the pelvic sidewall and to the uterus by ligaments. These organs function to secrete hormones (estrogen and progesterone) and to produce the female germ cells (oocytes). Ovaries: Anatomy
  • Can delineate the external uterine contour well
  • Cannot visualize anatomy within the uterine cavity
• Pelvic MRI: 
  • Can aid in diagnosis when ultrasonography is inconclusive
  • Can delineate both the internal and external uterine contours (e.g., can differentiate between septate and bicornuate uteri)
• Saline-infusion sonography Sonography The visualization of deep structures of the body by recording the reflections or echoes of ultrasonic pulses directed into the tissues. Use of ultrasound for imaging or diagnostic purposes employs frequencies ranging from 1. 6 to 10 megahertz. Diagnostic Procedures in Gynecology ( SIS SIS Infertility):
  • Sterile Sterile Basic Procedures fluid is injected into the uterine cavity through a catheter. The fluid distends the uterine cavity to allow real-time ultrasound images to be obtained.
  • Allows for assessment of the internal uterine cavity (in addition to all images obtained on traditional ultrasonography, like the external uterine contour as well)
  • Can identify septa, polyps, and submucosal fibroids Fibroids A benign tumor derived from smooth muscle tissue, also known as a fibroid tumor. They rarely occur outside of the uterus and the gastrointestinal tract but can occur in the skin and subcutaneous tissue, probably arising from the smooth muscle of small blood vessels in these tissues. Infertility
• Hysterosalpingography:
  • A fluoroscopic exam in which dye is injected into the uterine cavity and allowed to fill and spill from the fallopian tubes Fallopian tubes The uterus, cervix, and fallopian tubes are part of the internal female reproductive system. The fallopian tubes receive an ovum after ovulation and help move it and/or a fertilized embryo toward the uterus via ciliated cells lining the tubes and peristaltic movements of its smooth muscle. Uterus, Cervix, and Fallopian Tubes: Anatomy
  • Provides information about the inner contours of the uterine cavity and patency of the fallopian tubes Fallopian tubes The uterus, cervix, and fallopian tubes are part of the internal female reproductive system. The fallopian tubes receive an ovum after ovulation and help move it and/or a fertilized embryo toward the uterus via ciliated cells lining the tubes and peristaltic movements of its smooth muscle. Uterus, Cervix, and Fallopian Tubes: Anatomy
  • Does not provide information about the external uterine contour

Management

• Any obstructed areas should be surgically opened and/or resected to allow for full efflux of menstrual fluid.
• Uterine septa are typically resected hysteroscopically.
• Surgical repairs of bicornuate and didelphys anomalies are highly complex and rarely done since it is unclear whether they truly improve pregnancy Pregnancy The status during which female mammals carry their developing young (embryos or fetuses) in utero before birth, beginning from fertilization to birth. Pregnancy: Diagnosis, Physiology, and Care outcomes (which would be the only indication for such a repair).
• Isolated cervical agenesis Agenesis Teratogenic Birth Defects:
  • Consider medical management for menstrual suppression Suppression Defense Mechanisms until patient desires conception via ART:
    • Continuous use of combined estrogen Estrogen Compounds that interact with estrogen receptors in target tissues to bring about the effects similar to those of estradiol. Estrogens stimulate the female reproductive organs, and the development of secondary female sex characteristics. Estrogenic chemicals include natural, synthetic, steroidal, or non-steroidal compounds. Ovaries: Anatomy/progestin therapy (e.g., oral contraceptive Oral contraceptive Compounds, usually hormonal, taken orally in order to block ovulation and prevent the occurrence of pregnancy. The hormones are generally estrogen or progesterone or both. Benign Liver Tumors pills)
    • Progestin-only therapy
    • Gonadotropin-releasing hormone Gonadotropin-releasing hormone A decapeptide that stimulates the synthesis and secretion of both pituitary gonadotropins, luteinizing hormone and follicle stimulating hormone. Gnrh is produced by neurons in the septum preoptic area of the hypothalamus and released into the pituitary portal blood, leading to stimulation of gonadotrophs in the anterior pituitary gland. Puberty (GnRH) agonist (continuous GnRH suppresses FSH FSH A major gonadotropin secreted by the adenohypophysis. Follicle-stimulating hormone stimulates gametogenesis and the supporting cells such as the ovarian granulosa cells, the testicular sertoli cells, and leydig cells. Fsh consists of two noncovalently linked subunits, alpha and beta. Within a species, the alpha subunit is common in the three pituitary glycoprotein hormones (TSH, LH, and FSH), but the beta subunit is unique and confers its biological specificity. Menstrual Cycle, inducing a menopause-like state)
  • Surgical management:
    • Hysterectomy
    • Reconstructive surgeries to allow for menstruation Menstruation The periodic shedding of the endometrium and associated menstrual bleeding in the menstrual cycle of humans and primates. Menstruation is due to the decline in circulating progesterone, and occurs at the late luteal phase when luteolysis of the corpus luteum takes place. Menstrual Cycle (increased risks)

Congenital Malformations of the Vagina and Hymen

Development of vaginal and hymenal anomalies

• Like uterine anomalies, vaginal anomalies are due to:
  • Agenesis Agenesis Teratogenic Birth Defects/ hypoplasia Hypoplasia Hypoplastic Left Heart Syndrome (HLHS)
  • Lateral fusion defects → resulting in vertical septa
  • Vertical fusion defects → resulting in transverse septa
• The hymen Hymen A thin fold of mucous membrane situated at the orifice of the vagina. Vagina, Vulva, and Pelvic Floor: Anatomy is a transverse membrane made of fibrous Fibrous Fibrocystic Change connective tissue Connective tissue Connective tissues originate from embryonic mesenchyme and are present throughout the body except inside the brain and spinal cord. The main function of connective tissues is to provide structural support to organs. Connective tissues consist of cells and an extracellular matrix. Connective Tissue: Histology:
  • The embryologic junction of the sinovaginal bulbs and the urogenital sinus
  • Normally perforates, becoming patent in fetal life → creates a connection between the vaginal lumen and the external genital structures
  • Failure of perforation Perforation A pathological hole in an organ, blood vessel or other soft part of the body, occurring in the absence of external force. Esophagitis can result in hymenal anomalies.

Types of vaginal anomalies

• Longitudinal vaginal septum:
  • May be partial or complete (coming all the way down to the vaginal introitus)
  • Obstructed hemivagina: when a longitudinal septum joins the lateral wall, creating an obstructed area of vagina Vagina The vagina is the female genital canal, extending from the vulva externally to the cervix uteri internally.

Uterus, Cervix, and Fallopian Tubes: Anatomy, uterine body, and fallopian tubes Fallopian tubes The uterus, cervix, and fallopian tubes are part of the internal female reproductive system. The fallopian tubes receive an ovum after ovulation and help move it and/or a fertilized embryo toward the uterus via ciliated cells lining the tubes and peristaltic movements of its smooth muscle. Uterus, Cervix, and Fallopian Tubes: Anatomy are also typically absent.
    • Ovaries Ovaries Ovaries are the paired gonads of the female reproductive system that contain haploid gametes known as oocytes. The ovaries are located intraperitoneally in the pelvis, just posterior to the broad ligament, and are connected to the pelvic sidewall and to the uterus by ligaments. These organs function to secrete hormones (estrogen and progesterone) and to produce the female germ cells (oocytes). Ovaries: Anatomy (non-Müllerian structures) are usually present and normal.

Uterus, Cervix, and Fallopian Tubes: Anatomy and ovaries Ovaries Ovaries are the paired gonads of the female reproductive system that contain haploid gametes known as oocytes. The ovaries are located intraperitoneally in the pelvis, just posterior to the broad ligament, and are connected to the pelvic sidewall and to the uterus by ligaments. These organs function to secrete hormones (estrogen and progesterone) and to produce the female germ cells (oocytes). Ovaries: Anatomy are all typically present and normal.

Types of hymenal anomalies

• Imperforate hymen Hymen A thin fold of mucous membrane situated at the orifice of the vagina. Vagina, Vulva, and Pelvic Floor: Anatomy
• Microperforate or cribriform perforations
• Septate

Clinical presentation

• Completely obstructive anomalies (e.g., transverse vaginal septa, vaginal agenesis Agenesis Teratogenic Birth Defects, imperforate hymen Hymen A thin fold of mucous membrane situated at the orifice of the vagina. Vagina, Vulva, and Pelvic Floor: Anatomy):
  • Inability to fully penetrate the vagina Vagina The vagina is the female genital canal, extending from the vulva externally to the cervix uteri internally. The structures have sexual, reproductive, and urinary functions and a rich blood supply, mainly arising from the internal iliac artery. Vagina, Vulva, and Pelvic Floor: Anatomy during:
    • Tampon insertion
    • Intercourse
    • Physical exam
  • If a functional uterus Uterus The uterus, cervix, and fallopian tubes are part of the internal female reproductive system. The uterus has a thick wall made of smooth muscle (the myometrium) and an inner mucosal layer (the endometrium). The most inferior portion of the uterus is the cervix, which connects the uterine cavity to the vagina. Uterus, Cervix, and Fallopian Tubes: Anatomy and ovaries Ovaries Ovaries are the paired gonads of the female reproductive system that contain haploid gametes known as oocytes. The ovaries are located intraperitoneally in the pelvis, just posterior to the broad ligament, and are connected to the pelvic sidewall and to the uterus by ligaments. These organs function to secrete hormones (estrogen and progesterone) and to produce the female germ cells (oocytes). Ovaries: Anatomy are present, at menarche Menarche The first menstrual cycle marked by the initiation of menstruation. Menstrual Cycle patients Patients Individuals participating in the health care system for the purpose of receiving therapeutic, diagnostic, or preventive procedures. Clinician–Patient Relationship also experience:
    • Severe dysmenorrhea 
    • Cyclic or chronic pelvic pain Pain An unpleasant sensation induced by noxious stimuli which are detected by nerve endings of nociceptive neurons. Pain: Types and Pathways
    • Vaginal mass Mass Three-dimensional lesion that occupies a space within the breast Imaging of the Breast or bulge
• Incomplete obstructions (e.g., septate hymen Hymen A thin fold of mucous membrane situated at the orifice of the vagina. Vagina, Vulva, and Pelvic Floor: Anatomy, obstructed hemivagina) present with similar pain Pain An unpleasant sensation induced by noxious stimuli which are detected by nerve endings of nociceptive neurons. Pain: Types and Pathways symptoms and:
  • Irregular bleeding
  • Prolonged bleeding
• All vaginal and hymen Hymen A thin fold of mucous membrane situated at the orifice of the vagina. Vagina, Vulva, and Pelvic Floor: Anatomy anomalies can also present with pain Pain An unpleasant sensation induced by noxious stimuli which are detected by nerve endings of nociceptive neurons. Pain: Types and Pathways during intercourse (known as dyspareunia Dyspareunia Recurrent genital pain occurring during, before, or after sexual intercourse in either the male or the female. Primary Ovarian Insufficiency).
• Longitudinal vaginal septum versus septate hymen Hymen A thin fold of mucous membrane situated at the orifice of the vagina. Vagina, Vulva, and Pelvic Floor: Anatomy:
  • Bleeding despite using a tampon → longitudinal vaginal septum
  • Inability to remove a tampon after it is inserted → septate hymen Hymen A thin fold of mucous membrane situated at the orifice of the vagina. Vagina, Vulva, and Pelvic Floor: Anatomy. Because the tampon is thin in the applicator, it can fit through 1 side, but it expands once deployed and cannot be removed.

Diagnosis

• Diagnosis is typically achieved with a pelvic exam and ultrasonographic imaging.
• MRI can be used to differentiate between a high transverse septum and cervical/uterine agenesis Agenesis Teratogenic Birth Defects.
• All patients Patients Individuals participating in the health care system for the purpose of receiving therapeutic, diagnostic, or preventive procedures. Clinician–Patient Relationship with vaginal and hymenal anomalies should undergo pelvic imaging to look for associated uterine anomalies.
• On imaging, obstructive lesions may demonstrate:
  • Hematocolpos: accumulation of menstrual blood in the vagina Vagina The vagina is the female genital canal, extending from the vulva externally to the cervix uteri internally. The structures have sexual, reproductive, and urinary functions and a rich blood supply, mainly arising from the internal iliac artery. Vagina, Vulva, and Pelvic Floor: Anatomy
  • Hematometra: accumulation of blood in the uterus Uterus The uterus, cervix, and fallopian tubes are part of the internal female reproductive system. The uterus has a thick wall made of smooth muscle (the myometrium) and an inner mucosal layer (the endometrium). The most inferior portion of the uterus is the cervix, which connects the uterine cavity to the vagina. Uterus, Cervix, and Fallopian Tubes: Anatomy

Management

• For septa and hymenal anomalies: surgical resection
• For vaginal agenesis Agenesis Teratogenic Birth Defects:
  • Vaginal dilators used regularly can achieve good functional length (for intercourse) in a majority of patients Patients Individuals participating in the health care system for the purpose of receiving therapeutic, diagnostic, or preventive procedures. Clinician–Patient Relationship.
  • Specialized complex surgical procedures exist to create a neovagina if desired by the patient for penetrative intercourse.
