Study Notes

Male Reproductive System

Male gametes are called sperm.
Leydig cells are responsible for the secretion of testosterone.
The hypothalamic hormone that regulates the male reproductive system is gonadotropin-releasing hormone.
The primary function of the epididymis is sperm maturation and storage.
Spermatogenesis occurs within the seminiferous tubules.

Female Reproductive System

The female gonads are known as ovaries.
Oogonia undergo mitosis before birth.
The corpus luteum originates from the dominant follicle.
Fertilization of the egg typically occurs in the uterine tube.
After menopause, estrogen levels drop because there are no follicles left to produce estrogen.

Reproductive Structures

The vulva comprises the mons pubis, labia majora, and Bartholin's glands.
The development of testes or ovaries in an embryo is controlled by the presence of the Y chromosome.
Without SRY expression, an embryo will develop into a female.

Puberty and Influencing Factors

Several factors influence the timing of puberty, including genes, stress, and amount of body fat.
