Name the human male reproductive organ that produces sperms and also secretes a hormone. Write the functions of the secreted hormone.
OR
Trace the path of sperm during ejaculation and mention the gland and their functions associated with the male reproductive system.

Explanation

Testis Secrete the hormone testosterone and help in formation of sperm cells.
Function of Testosterone is the primary male sex hormone. Its functions to develop a man.s primary and secondary sex characteristics.
Path of sperm during ejaculation is testis to vas deferens to urethra. Along the path of vas deferens,glands like the prostate and the seminal vesicle add their secretion so that sperms are in fluid medium to make their transport easier. This fluid also provides nutrition.
Glands associated with male reproductive system are:
a] Prostate gland: serves to provide the force needed for ejaculation. It secretes thin, milky alkaline fluid that adjusts the pH of seminal fluid and serves in motility of sperms.
b] Cowper glands: Their secretion lubricates the end of penis during sexual intercourse and may contain few sperms.
c] Seminal vesicle: adds alkaline pH (to counteract acidic pH of vagina), fructose (a nutrient), mucus and coagulating and local acting enzymes.
