Study Notes
Developmental Defects
- Developmental defects in the female genital tract result from genetic or environmental influences.
- Common defects include:
- Müllerian Agenesis (Mayer-Rokitansky-Küster-Hauser Syndrome): Characterized by the absence of the uterus and upper vagina.
- Bicornuate Uterus: A uterus divided into two cavities due to incomplete fusion of Müllerian ducts.
- Septate Uterus: Presence of a septum dividing the uterine cavity, potentially leading to pregnancy complications.
- Imperforate Hymen: Condition where the hymen lacks an opening, affecting menstruation.
Embryological Development
- Female genital tract development begins around the 6th week of embryonic life.
- Initially, both male and female embryos possess Müllerian and Wolffian ducts.
- In the absence of anti-Müllerian hormone (AMH) and testosterone, Müllerian ducts develop into:
- Fallopian tubes
- Uterus
- Upper part of the vagina
- External genitalia also develop during this period.
Bicornuate Uterus
- Associated with an increased risk of preterm labor.
-
Complications:
- Obstructed Labor: Structural defects in the uterus may complicate labor, often necessitating a Cesarean section.
- Postpartum Hemorrhage: Uterine anomalies can lead to excessive bleeding after childbirth.
Obstetric Complications and Difficulties
- Developmental defects may contribute to various obstetric complications:
- Infertility: Conditions like Müllerian agenesis and severe bicornuate uterus can lead to inability to conceive.
- Recurrent Miscarriages: Septate uterus is linked with repeated pregnancy loss.
- Preterm Birth: Abnormal uterine structures, such as a bicornuate uterus, heighten the risk of preterm delivery.
- Obstructed Labor: Structural anomalies can result in challenges during the birthing process.
