In a newspaper article, Obstetrician-gynecologist Dr. Anna-Kay Taylor Christmas posits the view that infertility is a widespread problem which affects up to 15 per cent of the reproductive age population, and is often due to a combination of factors.
She argues that “Many men don’t like the thought of the problem lying with them, but for about one in five infertile couples the problem lies solely in the male partner. Male fertility generally relies on sperm quantity and quality, so if the number of sperm in a man’s ejaculate is low, or if the sperm is of poor quality (abnormal shapes or movements), it will be difficult for him to cause pregnancy.”
According to Dr. Taylor Christmas, some of the factors that can negatively affect male fertility include:
1. Varicocele (dilated veins in the scrotum).
2. Undescended testes.
3. Excessive estrogen exposure.
4. Infections of the male reproductive system.
5. Mumps as a child.
6. Prostate enlargement.
7. Endocrine (hormone/glandular) disorders affecting the brain, adrenals, thyroid, testes, leading to low testosterone production (including tumors, low functioning from birth, trauma).
8. Urethral strictures.
9. Sex chromosome (genetic) abnormalities.
10. Malnutrition (especially protein deficiency).
