Cholesterol Levels May Influence Male Fertility

Male fertility is decided by both sperm quality and sperm quantity. These two factors are decided by a wide variety of factors. While genetics may be the prime reason for male infertility, man-made factors also play important roles. Factors which promote an increase in blood cholesterol may depress male fertility. Strangely, low cholesterol levels also may affect male fertility. Obesity also antagonizes male fertility.

The sperm is the male reproductive cell. The word sperm is derived from the Greek word ‘sperma’ meaning ‘seed’. Sperm cells are produced within the testicles. They are ejected out of the male body in the semen. The sperm count in a single ejaculation runs into several millions and only a very few are fortunate in winning the race to reach the egg. Even among these, only a single sperm gets to penetrate the egg and merge with it. A sperm cell can survive in the female reproductive tract for nearly five days. Fertility depends on sperm quality as well as sperm quantity. Several factors can contribute to male infertility. The commonest causes are low sperm counts, the presence of abnormal sperms and sperms which are not motile. Total absence of sperms is also frequently encountered. In addition, other factors may also contribute.

High Cholesterol Levels Reduce Sperm Counts

Cholesterol is a double edged sword. High blood cholesterol levels are risky as are reduced levels as recent research indicates that low blood cholesterol levels may increase the risk for the onset of cancer. Cholesterol may be able to impact male fertility. Increased intake of saturated fat boosts blood cholesterol levels. Such conditions cause a reduction in the sperm counts. Conditions promoting an increase in LDL levels in the circulation can also produce a decrease in the number of sperms produced and therefore, in male fertility.

Low Cholesterol Levels Affect fertility

While elevated cholesterol levels are bad, reduced levels can also create problems for male fertility. Cholesterol is the precursor of steroid hormones including the sex hormones. Testosterone is a male sex hormone and a steroid hormone. As cholesterol levels fall, testosterone synthesis would also be depressed. Testosterone has several functions. The most important consequence of testosterone deficiency is a decrease in libido which is the most important factor for maintaining male fertility. Testosterone also promotes sperm production in the testicles. Thus, reduced testosterone levels reduce the sperm counts. Testosterone deficiency can also have other deleterious consequences like inability to produce erections and the inability to maintain firm erections. The ejaculate volume may also be reduced which can decrease the sperm counts.

Vitamin D promotes Male Fertility

Thus, red meat, processed meats, ice creams and cheeseburgers can reduce your sperm count. On the other hand, walnuts and fish can increase your sperm count. Both these foods are rich in omega-3-fatty acids. Saturated fats reduce sperm count by nearly 38%. Sperm motility is also affected. Vegetables and fruits improve the overall quality of life by keeping many diseases away. They also promote an increase in sperm quality and quantity. Testosterone was previously thought to function only as a sex hormone. However, it has shown up as a multifunctional substance. Vitamin D is following suit. Vitamin D and zinc supplementation can elevate sperm counts and improve sperm quality. It is important not to wear inner wear which are too tight. Such innerwear, tend to raise the temperature around the testicles and this pushes the sperm counts down. Increased frequency of sex plays a positive role. While this may slightly reduce the sperm count per ejaculate, this activity keeps the sperms in a healthy state. Obesity also pushes the sperm counts down. Hence, maintaining normal weight is beneficial for healthy male fertility.
