Top 10 Causes for Male Infertility

causes of female infertility

Men may also be a factor in a couple’s infertility. If a couple has had frequent, unprotected sexual contact for a year without becoming pregnant, they are deemed infertile. Infertility is categorised as male infertility when the female partner is a fertile woman. Consult a male infertility centre in trivandrum to diagnose your infertility issues. Fertility issues can result from a variety of different medical disorders and other variables, and each instance will likely have a unique set of causes, multiple causes, or in extreme cases, no known causes at all. Overall, one-third of cases of infertility are brought on by problems with male reproduction, one-third by problems with female reproduction, and one-third by problems with both male and female reproduction or for unidentified reasons. 

Male infertility causes typically don’t have obvious signs; a couple usually becomes aware of a problem when they discover they are unable to conceive naturally and need professional assistance. Common 10 causes for Male infertility are listed below.


A BMI of over 30 can affect sperm quality because fat deposits can overload and affect the metabolism of androgens (hormones that affect male characteristics and reproductive activity), particularly testosterone. There is growing evidence that male obesity has a severe impact on male fertility, particularly changing the physical and molecular structure of germ cells in the testes and ultimately mature sperm.

Smoking and addictive substances

Substance usage among men can lead to problems with fertility and reproductive health. Men who abuse alcohol or drugs, or who suffer from addiction, are more likely to experience problems with their sexual and reproductive function due to the drugs’ disruption of hormones, damage to blood vessels, which causes erectile dysfunction, and even harm to sperm quality and quantity.


The increased radiation exposure brought on by cell phone use is thought to be a major lifestyle factor impacting fertility. This is one of the main causes for male infertility. Men’s semen quality decreased as a result of increased cell phone use, which also affected sperm count, motility, and vitality. It was correlated with modifications in sperm morphology (sperm size and shape). The majority of men regularly carry their phones in their pants pockets. Additionally, a majority of men use hands-free devices while using their phones on their laps. Since cell phones produce heat, which increases the temperature of the testes, this is a dangerous practice. To reduce the risk, men should avoid keeping their cell phones close to their testicles and scrotum.


Antioxidant-rich foods can help maintain male fertility. Examples of foods rich in antioxidants include cheese containing vitamin A, oranges containing vitamin C, sunflower seeds containing vitamin E, fish containing omega-3 fatty acids, broccoli containing folic acid, and beans and artichokes.

Supplements and steroids

Products that some men use to look younger and fitter may also raise their chance of infertility. The risk of infertility can be raised by several chemical and hormonal supplements. High doses of testosterone-boosting supplements dramatically reduce a man’s sperm count. A doctor should be consulted before using any supplement or medication that claims to boost libido or increase muscle mass in order to fully understand the risks to reproduction involved.

High Testicular Temperature

High temperatures may harm sperm function and production. Regular use of saunas or hot tubs may temporarily lower sperm count. Long hours of sitting, tight clothing, or prolonged use of a laptop computer can all raise the temperature in the scrotum and somewhat lower sperm production.


Another causes for male infertility are sexually transmitted infections (STIs), such as gonorrhoea, chlamydia, and ureoplasma These microorganisms cause genital inflammation, which influences sperm quality alterations. Severe and persistent cases of these infections can also result in blockage. Any indication of infection needs to be promptly detected and treated with antibiotics.

Genital Injuries 

Any testicular injuries that develop during a man’s lifetime must always be treated right away. Otherwise, fertility may suffer long-term effects. Although it is well acknowledged that exercise is essential for maintaining excellent physical health, extreme caution is required, especially when participating in certain sports where the testes are not adequately protected and could suffer serious harm (e.g. martial arts, cycling, horse-riding). When participating in such activities, men are encouraged to wear a jockstrap (undergarment supporter designed to support male genitalia).



Sperm quality declines over time, and research conducted in sperm banks has shown that the decline in sperm count and quality after the age of 40 is significant. This does not imply that a man in his 50s or 60s cannot conceive, but conception does become much more challenging as one gets older. Of course, the condition of the man’s general health also plays a role in this.


Male infertility is often caused by varicocele. Given that it exhibits no signs, it is exceedingly sneaky. Testicular dysfunction caused by testicular vein distention and insufficiency is known as varicocele. Surgery is used to treat varicocele, and the most dependable technique is microsurgical correction. Depending on how affected sperm parameters were prior to surgery, surgery outcomes for infertility rely on this.
