Testosterone in Reproductive Function
In a male body
regulate sex drive (libido)
regulate bone mass& fat distribution
regulate muscle mass and strength
production of red blood cells and sperm
In female body
Development reproductive organs during fetal development
Growth, maintenance, and repair of a woman's reproductive tissues and bone mass

Ovaries
Negative feedback mechanism of the sex hormones
In female : estrogen and progesterone from developing follicles contribute to this feedback, while in males, inhibin and testosterone are involved.
In males, inhibin, released with high sperm count, slows spermatogenesis, inhibiting GnRH and FSH; in females, reproduction control involves hormones from the hypothalamus, anterior pituitary, and reproductive organs.
Oogenesis Steps
. Pre-natal Stage
Antral Stage
Pre-ovulatory Stage
Hormonal changes in menstrual cycles
Follicular (estrogen rise), Ovulation (LH surge), Luteal (corpus luteum produces estrogen and progesterone).
Path of an oocyte from the ovary to fertilization
Oocyte is released from the ovary and, aided by cilia, travels through the fallopian tube to the uterus, where fertilization with a sperm typically occurs; following fertilization, the resulting zygote undergoes multiple cell divisions as it moves towards the uterus, ultimately implanting into the thickened uterine lining and continuing its development.
