Pair of exocrine glands near male urethra.
- secrete fluid into urethra. Aka; Cowper glands
What is ejaculation?
Ejection of sperm + fluid from male urethra.
What is the ejaculatory duct?
Tube through which semen enters urethra.
What is the epididymus?
One of a pair of long tightly coiled tubes above each testis.
Store and carries sperm from seminiferous tubules to vas deferns.
What is erectile dysfunction?

Sensitive tip of penis; comparable to clitoris.
What are identical twins?
2 infants resulting from division of 1 fertilized egg into 2 embryos.
1 egg/1 sperm/1 placenta/2 amniotic sacs (egg splits)
What are interstitial cells?
(Cells of testes)
- specialized cells, lie adjacent to seminiferous tubules in testes.
Produce testosterone. Also leydig cells
What is parenchymal tissue?
Essential distinctive cells of an organ.
In testis, seminiferous tubules are parenchymal.
What is the penis?
Male external organ of reproduction.
What is the perineum?

What is semen?
Spermatozoa (plural, sperm cells) and seminal fluid (prostatic and seminal secretions) discharged from urethra during ejaculation.
What are seminal vesicles?
Paired sac-like exocrine glands that secrete fluid (major part of semen) into vas deferens.
Seminiferous tubules?
Narrow, coiled tubules that produce sperm in testes.
What is spermatozoon?
Sperm cell.
What is sterilization?
Procedure that removes a person’s ability to produce or release reproductive cells; removal of testicles, vasectomy, oophorectomy
What is stromal tissue?
Supportive, connective tissue of an organ. Aka stroma.
