follicle-stimulating hormone (FSH)
Hormone produced by the pituitary gland; stimulates maturation of the ovum.
Developing sac enclosing each ovum within the ovary. Only about 400 of these sacs mature in a woman's lifetime.
human chorionic gonadotropin (HCG)
Hormone produced by the placenta to sustain pregnancy by stimulating (-tropin) the mother's ovaries to produce estrogen and progesterone.
Lips of the vagina; labia majora are the larger outermost lips, and the labia minora are the smaller, innermost lips.

interstitial cells of the testis
Cells that lie between the seminiferous tubules and produce the hormone testosterone. A pituitary gland hormone (luteinizing hormone [LH]) stimulates the interstitial cells to produce testosterone.
parenchymal tissue (parenchyma)
Tissue composed of the essential cells of any organ. In the testes, parenchymal tissue includes seminiferous tubules that produce sperm.
Gland at the base of the urinary bladder that secretes fluid into the urethra during ejaculation.
Any procedure rendering an individual incapable of reproduction; vasectomy and salpingectomy are examples.
testis (plural: testes)
Male gonad that produces spermatozoa and the hormone testosterone; testicle.
