Male Semens
Male Semen: Semen is the milky-Colored, somewhat gel-like liquid that spurts out of the penis during orgasm. Male Semen produced not in the testicles as many think, but by the small plum-size prostate gland, which sits just below the bladder, and by the seminal vesicles, two pinkie-size glands that feed into the prostate. Male Semen is actually a very sophisticated substance. It contains nutrients to keep sperm alive after ejaculation, Substances to protect the sperm from the chemical environment of the vagina, and special enzymes to make it thin out (liquefy) about fifteen minutes after ejaculation.
The average amount (volume) of semen expelled by a healthy man in one ejaculation is about a teaspoon (3 to 5 cubic centimeters). And the semen should spurt or shoot out of the penis, not dribble. Many things in addition to simple aging can reduce the volume of the semen or impair the way it is expelled.
Environmental factors be affecting male fertility
- Endocrine disrupters
- Toxic pollutants
- Sexually transmitted infections
- Zinc deficiency
- Alcoholism
- Smoking
- Anabolic steroid use
- Ionising radiation.
Endocrine disrupters are chemicals present in the environment that, by virtue of their ability to adversely affect the endocrine (hormonal) system, cause health consequences. Several industrial pollutants can affect fertility, as can smoking and alcohol use. Some of these toxins can cause reproductive disorders, neurological disease, immune system disorders and cancer.
