To have a successful pregnancy, a man’s sperm should combine with a woman’s egg. However, studies have shown that one-third of infertility cases are caused by male reproductive issues, one-third by female reproductive issues, and one-third by both male and female reproductive problems or due to unknown factors. There are various factors that affect a man’s fertility.
In this article, we will discuss several factors that affect a man’s fertility and some ways on how a man can boost his fertility rate.
Factors Affecting a Man’s Fertility
Harry Fisch wrote in the book The Male Biological Clock that the male biological clock is different when compared to a woman’s as it ticks at a different rate, causing an entirely different set of bodily and behavioral changes over the course of a lifetime. Male fertility, testosterone levels, and sexuality all certainly decline with age. Studies revealed that men older than 35 are twice as likely to be infertile as men 25 or younger.
Moreover, he added that the male biological clock affects more than fertility, affecting sexual performance, overall physical health, mental function, and intimate relationships. It ticks slower and more steadily that’s why its effects are less obvious. Below are some of the common factors affecting a man’s fertility:
- Reproductive age – the quality of sperm is negatively affected by age.
- Hormonal imbalances – older men may experience a slow decline in their testosterone over a period of years.
- Lack of sperm count – Some hormonal problems like testicular failure and varicocele lead to a lack of sperm production.
- Heat – Spa pools, saunas, and hot baths raise one’s body temperature which can affect a man’s testicles. This may lead to a reduction in sperm count.
- Smoking, alcohol, and drugs – An article has shown that smoking can affect the DNA enclosed in sperm while alcohol can cause impotence and reduce libido, affecting the quality of sperm.
- Overweight – Being immensely overweight can reduce fertility.
- Exposure to toxic chemicals – Many toxic chemicals are hazardous to a man’s reproductive system.
Ways on How a Man Can Boost His Fertility Rate
One of the essential factors for fertility in men is assessing their sperm count performed by certified and professional fertility doctors during routine semen analysis. Some experts consider a healthful sperm count to be 15 million per milliliter (ml) or at least 39 million per ejaculate. So, if the sperm count is below 15 million, it may cause fertility problems. Also, studies have shown that factors affecting testosterone levels have the most critical effect on sperm number and quality.
In this section, we will provide some ways on how a man can boost his fertility rate:
- Have proper exercise and sufficient sleep
A certain study has shown that regular exercise can increase sperm count and motility in men who have obese and sedentary lifestyles. While having a night of proper sleep is necessary for the repair and regeneration of the cells in the overall body system which includes the male reproductive system.
- Eat more antioxidant-rich foods
Foods rich in antioxidants may contribute to a healthy sperm count. So, search for foods rich in beta-carotene, vitamin C, beta-cryptoxanthin, and lutein.
- Increase omega-3 and omega-6 intake
A 2019 review of three studies has shown that males with infertility who were supplemented with omega-3 fatty acids had a significant improvement in their sperm motility and concentration.
- Avoid smoking, excessive alcohol, and drug use
- Avoid some prescription medicines
Some potent antibiotics, antidepressants, antipsychotics, anti-inflammatory drugs, anabolic steroids, methadone, opiates, and supplementary testosterone may temporarily reduce sperm production and development.
- Get enough Vitamin D, calcium, folate, and zinc
Vitamin D, calcium, folate, and zinc appear to improve sperm production, as well as the overall health of the sperm, its concentration, and count.
- Avoid being exposed to toxic chemicals
Some of the factors affecting a man’s fertility are reproductive age, hormonal imbalances, lack of sperm count, heat, smoking, alcohol, drugs, overweight, and exposure to toxic chemicals. So, in order to boost a man’s fertility, he should have proper exercise and sufficient sleep, eat more antioxidant-rich foods, increase omega-3 and omega-6 intake, get enough vitamin D, calcium, folate, and zinc, avoid smoking, excessive alcohol, and drug use, avoid some prescription medicines, and avoid being exposed to toxic chemicals.
