Study Notes
Reproductive Development and Maturation
- Girls are experiencing reproductive maturation at earlier ages (9-12 years).
- The hypothalamus may trigger gonad function in response to critical weight (approximately 95 lb or 43 kg).
- A lack of body fat can delay menstruation and affect female athletes and those with eating disorders.
Intrauterine Development
- Uterus is supported by ligaments, fascia, and muscle, allowing it to enlarge during pregnancy.
- Variations in uterine formation can lead to conditions like a bicornuate uterus, affecting fertility and pregnancy.
Types of Uterine Deviations
- Anteversion: The uterus is tipped forward.
- Retroversion: The uterus is tipped backward.
- Anteflexion: The uterus bends sharply forward.
- Retroflexion: The uterus bends sharply backward.
Vaginal Anatomy and Function
- The vagina extends from the cervix to the vulva, serving as the organ of intercourse and a birth canal.
- The anterior vaginal wall measures about 6-7 cm, while the posterior wall is 8-9 cm long.
- Fornices provide areas for semen pooling after coitus, facilitating sperm migration.
Vaginal pH and Hygiene
- Normal vagina pH is typically acidic, which prevents infections.
- After menopause, vaginal pH may approach neutral (7.5), increasing susceptibility to vulvovaginitis.
Menstrual Cycle Phases
- The menstrual cycle consists of distinct phases:
- Menstrual Phase: Shedding of the endometrium, marked by blood, mucin, and tissue fragments.
- Proliferative Phase: Occurs when estrogen stimulates endometrial growth post-menstruation.
- Secretory Phase: Following ovulation, progesterone leads to endometrial gland enlargement.
- Ischemic Phase: If fertilization does not occur, the corpus luteum regresses, leading to menstruation.
Fertility Considerations
- Uterine malformations can interfere with sperm migration and implantation, impacting fertility.
- Instructing women against daily douching is important to maintain vaginal flora and avoid infections.
