Factors That Affect Male Fertility

Factors That Affect Male Fertility

Several factors can influence male fertility. Among them are stress, Semen quality, sperm DNA fragmentation, and Testicular temperature. In addition, radiation therapy for cancer and other treatments can affect testicular function and cause temporary or permanent effects. A urologist will ask about any illnesses or medications you've taken in the past and your diet.

Semen quality

Several studies have indicated that semen quality is related to male fertility. Semen with low quality, low number of sperm, or both may indicate infertility. In addition, bacteria may affect sperm cell function and impair the spermatogenic process. Various urinary tract infections can impair sperm quality and male fertility, including acute/chronic prostatitis and chronic urethritis. Viral infections may also impair sperm motility.

Sperm DNA fragmentation

DNA fragmentation analysis can be used to determine the potential for a successful conception in males. Sperm contains large amounts of DNA, surrounded by protective protein structures. Together, they make up the chromatin of sperm. If the DNA is fragmented beyond 30 per cent, the sperm's chances of conceiving are low.

Testicular temperature

The relationship between testicular temperature and male fertility is not entirely clear. However, one study found a correlation between elevated testicular temperature and reduced sperm production. The researchers exposed 27 healthy men to mild epididymal and testicular temperature increases for 15 hours per day. They found that the men's sperm counts decreased by up to 80%. Moreover, a sustained increase in temperature affected the morphology of sperm.


Men who are under high-stress levels are less likely to conceive. It isn't known exactly how stress affects fertility, but it's expected that it negatively impacts sperm quality and concentration. Because these two factors can make it difficult for a man to conceive, stress management can help him improve his fertility.

Dietary supplements

Dietary supplements for male fertility can be a good option if you have trouble conceiving. Some studies show that a man who eats a balanced diet and supplements can increase his chances of conception. Dietary supplements can also help a man to maintain an adequate sperm count.
