- Bulbourethral Glands
- Two Exocrine glands near the male urethra.
- Ductus Deferens
- Vas Deferens.
- Cowper Glands
- Bulbourethral Glands.
- Ejaculation
- Ejection of sperm and fluid from the male urethra.
- Ejaculatory Duct
- 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 the enter the vas deferens.
- Flagellum
- Hair-like process on a sperm cell that makes it motile (able to move).
- Fraternal Twins
- Twins resulting from two separate, concurrent fertilizations.
- Glans Penis
- Sensitive tip of the penis.
- Identical Twins
- 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 (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.
- Perineum
- Area between the anus and scrotum in the male.
- Prepuce (foreskin)
- Skin covering the tip of the penis.
- Prostate Gland
- Gland at the base of the urinary bladder that secretes a fluid into the urethra during ejaculation.
- Scrotum
- External sac (double pouch) that contains the testes.
- Semen
- Spermatozoa and fluid (prostatic and other glandular secretions).
- Seminal Vesicles
- Glands that secrete a fluid into the Vas Deferens.
- Seminiferous Tubules
- Narrow, coiled tubules in the testes that produce sperm.
- Spermatozoon (Plural: Spermatozoa)
- Sperm Cell.
- Sterilization
- Any procedure rendering an individual incapable of reproduction; Vasectomy and Salpingectomy are examples.
- Stroma
- Supportive, connective tissue of an organ.
- Testis (Plural: Testes)
- Male Gonad that produces Spermatozoa and the hormone testosterone; Testicle.
- Testosterone
- Hormone secreted by the interstitial tissue of the testes; responsible for male sex characterisitics.
- Vas Deferens
- Narrow tube (one on each side) that carries sperm from the epididymis into the body and toward the urethra.
