Although the core causes of infertility in male are overwhelmingly physiological, the resulting heartache may possibly impose a massive psychological toll. Couples handling infertility may perhaps steer clear of social conversation and also struggle with nervousness-linked sexual dysfunction and other marital conflicts.

What causes infertility in men? A number of maladies ranging from hormonal disturbances to bodily complications, to psychological issues can result in male infertility. The hormonal problems may either be linked to abnormal functioning of gonads or the master endocrine gland—the pituitary gland. The pituitary gland is actually a pea-sized structure situated at the bottom of the brain, slightly below the hypothalamus and hooked up to it by nerve fibers. It's creates hormones which manage other glands and different bodily features. The anterior lobe of pituitary gland is principally involved in advancement of the human body, sexual maturation and reproduction. When fails to secrete GNSH, the gonad (testes) doesn’t get signals to secrete sex hormones that is responsible for the development of secondary sexual characteristics.
However, male infertility accounting from hormonal problems makes up a small percentage of the population of infertile males. The other possible causes include birth complications, radiation damage, and chemical use. Often surgical procedures like vasectomy can cause sperms to come into contact with blood thereby invoking the immune system to produce antibodies against it. The presence of antibodies in semen leads to sperm destruction.

Rarely, Infertility  may arise due to chromosomal abnormality like klinefelter syndrome, which may also be genetic in nature.
