British scientists have refuted the idea that giving up alcohol and smoking somehow improves the sperm of men suffering from infertility.
This conclusion was made by scientists from the University of Manchester after studying data on more than 2,200 representatives of the stronger half from 14 clinics that treat infertility. The men were asked to fill out questionnaires asking them about their lifestyle. The researchers then compared the results of their answers with the results of sperm analysis.
It turned out that some factors did affect the number of live sperm. For example, low concentrations were found in men who had undergone surgery on their testicles, dark-skinned men, and those who did heavy physical labor. Interestingly, alcohol habits, drug use, smoking, and excess weight had almost no effect on sperm quality.
Despite the fact that lifestyle plays a big role in our health, the results of the experiment show that bad habits do not affect the number of live sperm in semen, scientists say.
