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.
