Let’s discuss in detail, what are the factors which affect male fertility.

Factors that affect male fertility


As with age, female fertility is reduced, the same happens with a male. The blood testosterone starts decreasing as the male gets around the age of 30. By the time male is between 52 to 79, they have lower semen volume, abnormal sperm shape, and reduced vitality. So, your age will make a difference in your fertility.


If you smoke, then your fertility level is bound to decline along with sperm movement. There are high chances that % of normal sperm cells will be reduced when you smoke. Due to smoking, the oxidative stress in the environment is increased which is not beneficial for sperm health. From sperm concentration to sex drive, smoking can result in negative effects.


If you are overweight or obese, then fertility can get impacted. You must keep your body weight right. You should consult the doctor and understand the BMI i.e. Body Mass Index. When you have the right body weight, the sperm will move normally and there will be no problem.

Occupational exposure

The environment in which you work can also result in a negative impact. By this, we mean that exposure to harmful chemicals at the workplace can reduce semen quality. The studies have shown that people in the agriculture sector or where there is the use of pesticides and chemicals have low sperm count.


Exercise is important to keep yourself physically fit and active all day long. In the same manner, exercise plays an important role in the proper functioning of male reproductive health. You need to make sure that you are following a healthy workout regime daily. Although, there is no need to get involved in a strenuous exercise regime as studies have shown that it can affect the semen parameters and even the testosterone level is declined.

Scrotal temperature

If you wear tight or fitting under trousers then it can impact the scrotal temperature. In addition, if you sit for a long time like driving for more than 2 hours then its temperature will increase. The rise in scrotal temperature can affect the semen quality which can make it difficult for the couple to get pregnant.


Varicocele is the condition when testicular veins are dilated and these hold the testicles. It is one of the common reasons for infertility. Around 30% to 40% of infertility cases are due to this issue.

Endocrine disorders

The endocrine cause is another reason when male fertility is affected. These are also referred to as testicular causes which can affect fertility.


Hypogonadism is the condition when the pituitary gland is not able to produce the necessary hormones in the right amount. Hormonal imbalance can result in low sperm count which is the reason for infertility. Moreover, sperm motility and sperm quality may be affected.

Male reproductive tract infection

It is normal for men to have male reproductive tract infection, but when timely treatment is not taken it can affect fertility. Due to the infection, the male accessory gland is impaired which leads to fertility. Due to this, the semen volume is reduced which eventually makes it difficult for the women to conceive.

Apart from these factors, genetic or chromosomal issues can also affect male fertility. However, the problem can be addressed and for that, you need to take medical evaluation from the best fertility expert in your area.
