Leydig cells are interstitial cells located adjacent to the seminiferous tubules in the testes. The best-established function of Leydig cells is to produce the androgen, testosterone, under the pulsatile control of pituitary luteinizing hormone.
Sertoli cells keep the germ cells that start the process healthy and nourished. They also function at the end of spermatogenesis by absorbing extra cytoplasm from newly created spermatozoa, just prior to their release into the lumen of the seminiferous tubule.
Primary spermatocytes are present in the
testes. They are diploid cells that are derived
from the spermatogonia. They undergo meiotic
division to give rise to secondary spermatocyte
and thereby male gamete-sperm.
(b) The male accessory glands include the
seminal vesicles, prostate gland, and the
bulbourethral glands whose secretions
constitute the seminal plasma, which provides
energy and motility to the sperms until they
reach the ovum
Prostate Gland: It stores and secretes an
alkaline, milky fluid known as pre-ejaculate. The
purpose of the alkalinity of the semen is to
neutralize the acidity of the vaginal tract.
Bulbourethral glands: This gland secretes
viscous secretion during sexual arousal. This
fluid helps to lubricate the urethra for easy
passage of spermatozoa to pass through, and to
help flush out any residual urine or foreign
matter.
