Developing sac enclosing each ovum within the ovary. Only about 400 of these sacs mature in a woman's lifetime.
human chorionic gonadotropin (HCG)

Hemolytic disease in the newborn caused by a blood group (Rh factor) incompatibility between the mother and the fetus.
hyaline membrane disease
Respiratory problem primarily in the premature neonate; lack of protein in the lining of the lung tissue causes collapse of the lungs. Also known as respiratory distress syndrome.

Tube formed by the union of the vas deferens and the duct of the seminal vesicles, opening into the urethra at the prostate gland.
epididymis (plural: epididymides)
Tube located on top of each testis; it carries and stores the sperm cells before they enter the vas deferens. Didymos is a Greek work for testis.
Twins resulting from the separation of one fertilized egg into two distinct embryos.
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.
Hormone secreted by the interstitical tissue of the testes; responsible for male sex characteristics.
Narrow tube (one on each side) that carries sperm from the epididymis into the body and toward the urethra.
