Cells located in the seminiferous tubules that divide mitotically to increase their numbers. They are diploid with 46 chromosomes.

A primary spermatocyte undergoes the first meiotic division, also known as reduction division. This division results in two equal, haploid cells called secondary spermatocytes.

Secondary spermatocytes undergo the second meiotic division. This produces four equal, haploid cells called spermatids.

Spermatids transform into mature sperm cells through a process called spermiogenesis. This includes changes to the cell structure.

The process by which mature sperm are released from the seminiferous tubules into the lumen. It is facilitated by Sertoli cells.

Highly coiled tubes within the testes where sperm production takes place.

The pouch that holds the testes outside the body cavity, allowing for a slightly lower temperature ideal for sperm production.

Cells lining seminiferous tubules that nourish developing sperm.

The male reproductive system is located in the pelvis region and comprises a pair of testes, accessory ducts, glands and external genitalia.

Hormone-producing cells located in the interstitial spaces of the testes.

The testes are responsible for producing sperm cells.

The process of egg formation in the ovaries.

Male sex hormones produced by Leydig cells, primarily testosterone.

A system of ducts that transport sperm from the testes to the urethra.

The transfer of sperm into the female genital tract.

The fusion of a sperm and an egg cell, leading to the creation of a zygote.

The external male reproductive organ responsible for delivering sperm.

Fluids produced by various glands in the male reproductive system that nourish and protect sperm.

The attachment of a fertilized egg to the uterine wall.

The primary female sex organ that produces the female gamete (ovum) and several steroid hormones (ovarian hormones).

One on each side of the lower abdomen. Connected to the pelvic wall and uterus by ligaments.

A thin epithelium that encloses the ovarian stroma. It's divided into a peripheral cortex and an inner medulla.

Funnel-shaped part of the fallopian tube closest to the ovary. It's lined with finger-like projections called fimbriae that capture the ovum during ovulation. It connects to the wider ampulla.

Wider part of the fallopian tube extending from the infundibulum towards the uterus. It serves as a passageway for the ovum towards the uterus.

The last part of the fallopian tube, it connects to the uterus. It has a narrow lumen.

A single, inverted pear-shaped organ. It's supported by ligaments attached to the pelvic wall and opens into the vagina through the cervix.

The lower portion of the uterus that connects to the vagina. Its cavity is called the cervical canal which, along with the vagina, forms the birth canal.

The outer layer of the uterus, composed of a thin membrane.

The middle layer of the uterus, composed of thick smooth muscle, responsible for contractions during childbirth.

The innermost layer of the uterus, a glandular lining that undergoes cyclical changes during menstruation.

The fleshy folds of tissue that surround the vaginal opening.

Paired folds of tissue located under the labia majora.

A tiny finger-like structure located at the upper junction of the labia minora, above the urethral opening.

A membrane that partially covers the vaginal opening.

The process of gamete production in the testes (sperm) or ovaries (ova).
