I believe that in past, if a couple was unable to conceive for a long time, family members or neighbors blamed problem on woman, saying that woman is "a chicken that does not lay eggs." But do not dump all problems on women, because not only women affect conception, men also affect conception. Below are a few factors that affect conception of a man, let's consider together.

First, long-term smoking and drinking

Young men are currently under a lot of pressure and men's pastimes are smoking and drinking, but if you smoke and drink frequently during pregnancy, it will affect sperm quality and lead to reduced fertility. This is because nicotine and other harmful substances in tobacco will increase chance of sperm deformation, and alcohol will affect intellectual development of fetus, so if you want to conceive a healthy child, you must stop smoking and drinking.

Second, obesity

In recent years, people have more mental activity, but less physical labor. Many office workers simply stay at home when they rest, which leads to bodies getting fatter and fatter. Excessive fat leads to an increase in body temperature, which affects ability of testicles to spermatogenesis and at same time a decrease in sperm production, and obesity can also cause diabetes, which can damage DNA in sperm, leading to reduced fertility.

Third, high temperature activity

You should know that a suitable testicular temperature is around 35 degrees. If testicle is active for a long time at high temperature, it will affect production of sperm. Some male friends like to wear tight jeans or ride a bike for a long time, which will affect sperm viability. Sedentary lifestyle is also main reason affecting sperm motility.

Fourth strong partial eclipse

During pregnancy, diet is very important. Not only women need to supplement adequate nutrition, men also need to supplement nutrition, but if you often eat partial diets, it will inhibit growth of sperm, so men should eat more - quality protein foods: such as soybeans, lean meats, eggs, etc. e.

After reading above answers, I think everyone understands that if a couple is infertile for a long time, they should find out problems of both parties. This is not only a woman's problem, a man also needs to check if sperm is of good quality and healthy, as well as whether reproductive organs Health, so that problem can be detected as early as possible and treated in time.
