Study Notes

The Reproductive System Overview

The reproductive system consists of sex organs and associated brain parts that facilitate reproduction.
Its primary function is combining genetic material from the mother’s egg and the father’s sperm to create offspring, typically through sexual intercourse.

Male Reproductive Organs

Testes are the key male structures responsible for producing sperm, which carry genetic material.
Penis serves to deliver sperm into the female reproductive tract, enhancing the likelihood of fertilization.

Female Reproductive Organs

Ovaries produce eggs, with females generally releasing one egg per month, in contrast to the millions of sperm produced daily by males.
Uterus is a muscular organ that supports fetal development during pregnancy.
Breasts produce milk through lactation, essential for nourishing the baby and boosting its immune system.

Hormonal Functions

The reproductive systems also release hormones that significantly influence bodily functions, known as sex hormones.
Testosterone, produced in the testes, promotes masculine traits such as body hair and muscle growth, and may also influence aggression.
Estrogen and progesterone, produced by the ovaries, regulate egg release and contribute to feminine traits, including breast development.

Coordination of Reproduction

The reproductive system coordinates the meeting of sperm and egg through the interaction of the penis and vagina.
The penis deposits sperm within the vagina, enabling sperm to fertilize the egg.

Brain Control of Reproductive Functions

The hypothalamus in the brain controls the reproductive system by releasing gonadotropin-releasing hormone (GnRH).
GnRH stimulates the anterior pituitary gland to secrete luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which govern the functions of testes and ovaries.

Pregnancy and Gestation

Pregnancy initiates when a sperm fertilizes an egg, creating a zygote, which is the first cell of a new organism containing genetic material from both parents.
The zygote develops and implants into the uterus, leading to gestation, a process that involves the formation of all major organ systems and typically lasts about nine months.
Hormonal changes in the mother prepare for labor, the process by which the baby is born (parturition).
