Reproductive System Overview

The reproductive system's purpose is to create offspring. Gametes (sperm and egg) are formed through gametogenesis in the gonads (testes in males, ovaries in females).
Human cells typically have 46 chromosomes (diploid). Gametes are haploid, containing 23 chromosomes, produced by meiosis.
Male gametogenesis is spermatogenesis, occurring in the testes, producing millions of sperm.
Female gametogenesis is oogenesis, occurring in the ovaries, producing one egg per cycle.

Male Reproductive System

Spermatogenesis occurs in the testes, producing millions of sperm.

Female Reproductive System

The female reproductive system's functions include producing and releasing egg cells, facilitating fertilization, supporting pregnancy and childbirth, and providing nourishment (milk).
Ovaries: These contain follicles that develop and release eggs during ovulation. They have an inner medulla (blood vessels/nerves) and an outer cortex (containing follicles).
Fallopian Tubes: These have an infundibulum (nearest the ovary, with fimbriae that guide the egg), an ampulla (site of fertilization), and an isthmus that connects to the uterus.
Uterus: The uterus has three layers: perimetrium (outer), myometrium (muscle for contractions during labor), and endometrium (inner lining for implantation and placenta formation).
Vagina: An elastic, muscular canal connecting the external genitals to the uterus; it's also a birth canal and site of sperm deposition.
Mammary Glands: These specialized glands in the breast synthesize and secrete milk under hormonal influence.
Oogenesis: This occurs in the ovaries, beginning before birth and resuming at puberty, producing one mature egg and polar bodies per cycle.

Hormonal Regulation

Reproductive organs and processes are tightly regulated by hormones (e.g., testosterone, estrogen, and progesterone) for proper function and reproduction.

Explore the intricacies of the human reproductive system, including the processes of gametogenesis, spermatogenesis, and the roles of key organs like the testes and ovaries. This overview highlights how these systems work together to facilitate reproduction and support pregnancy.
