Physiology of Female Reproduction (??????)
  • Puberty (a) begins with the first menstrual
    bleeding (Menarche)
  • (b) begins when GnRH levels increase.
  • Menstrual Cycle FSH initiates development of the
    primary follicles.
  • LH stimulates ovulation and completion of the
    first meiotic division by the primary oocytes
  • The LH surge stimulates the formation of the
    corpus luteum. If fertilization occurs, HCG
    stimulates the corpus luteum persists.

9
Physiology of Female Reproduction (??????)
  • ????(II) If fertilization does not occur, the
    corpus luteum becomes the corpus albicans.
  • A ?????? mechanism causes ????? FSH and ??????LH
    levels to increase near the time of?? ovulation.
    ???Estrogen produced by theca cells of the
    follicle stimulates GnRH secretion.

11
Physiology of Female Reproduction (??????)
  • Menstrual cycle (IV) Uterine cycle
  • ?? (day 1 to day 4)- The spiral arteries
    constrict, and endometrial cells dies. MC is
    composed of blood,cells,etc.
  • ??? phase (day 5 to day 14)- Epithelial cells
    multiply and form glands, and the spiral arteries
    supply the glands.

12
Physiology of Female Reproduction (??????)
  • ??? phase (day 15 to day 28)- The endometrium
    becomes thicker, and the endometrial glands
    secrete.
  • Estrogen stimulates proliferation of the
    endometrium and synthesis of progesterone
    receptors. Decreased progesterone levels cause
    the spiral arteries to constrict and start
    menses.

13
Female Sexual Behavior
  • ????? sex drive is partially influenced by
    androgens (produced by the adrenal gland) and
    steroids (produced by the ovaries).
  • ??????? effects The???? erectile tissue of the
    ??clitoris and the bulbs of the vestibule become
    filled with blood. The ???? gland secrete
    ??mucus, and the ????vagina extrudes a mucuslike
    substance.

14
Female Fertility and Pregnancy (???????)
  • ???? Intercourse must take place 3 days before to
    1 day after ovulation if fertilization?? is to
    occur.
  • ???? Sperm cell transport to the ampulla depends
    on the ability of the sperm cells to ?? swim and
    possibly on ??contractions of the uterus and
    uterine tubes.

15
Female Fertility and Pregnancy (???????)
  • Implantation ??of the developing embryonic?? mass
    into the uterine wall occurs when the uterus is
    most receptive.
  • Estrogen and progesterone secrete first by the
    corpus luteum???? and later by the placenta ??
    are essential for the maintenance of pregnancy??.

16
Menopause
  • The female??? climacteric begins with irregular
    menstrual cycles and ends with menopause, the
    cessation of the menstrual cycle.
  • The major cause of menopause is the age-related
    changes in the ovary. A variety of symptoms
    occur, including hot flushes,??? ?? ?? ??
    irritability, anxiety, fatigue.

17
Conclusion
  • To be aware of the many facets of ????????
    sexuality-sexual values, the structure of sexual
    anatomy, aspects of ??? and sexual
    ?????responsiveness- is the first step toward
    attaining a healthy and fulfilling sex life.
    Menopause also affects quality of life.
  • Fertility ?? control refers to the quality of
    being fertile or productive. Contraceptives are
    the methods used to prevent conception.
