New Delhi. According to a research on sperm, after the age of 40, the level of fertility of men starts decreasing. Poor lifestyle is also affecting the quality of men’s sperm. A world leading IVF clinic has analyzed more than 40 thousand sperm tests. With this study, scientists understood that with the aging of a human being, his sperm quality starts declining.

Geneva’s fertility expert Dr. Sheryl Fua says that the situation of people above 55 years of age in this case is more weak. Dr. Phua said that many times the couples have difficulty in conceiving the child and in some circumstances, the couples are also difficult to miscarriage.

Fertility experts said that women often come forward in Geneva with such problems. But the study found that more than 40 percent of infertility cases are to mail reproduction ie men, which are often not told properly.

The expert further said, ‘We have noticed a significant decline in people’s sperm quality. This problem is associated with the real disadvantage of DNA and the package of genetic information which is kept by the sperm.

The father of two children David Hodge says that when he came to know about the high percentage of infertility in men, he was surprised, because people are afraid to talk openly on this subject.

David Hodge and his wife Sara tried to convey the child for three years before the sperm test. David said that he resorted to IVF (in vitro fertilization) technology for the child. David and Sara now have two daughters named Amy and Lila.

A previous published study at the ‘European Society of Human Reproduction and Embracity’ meeting in Vienna, Australia found that the capacity of male reproduction (male fertility) decreases to a great extent after reaching the age of 50.

According to the study, women face menopause at the age of 51 on an average. Scientists said on the basis of analysis that men also face equally infertility at this stage of age.

Researchers said that they have tracked about 4,200 men who produce a child with the help of IVF technology. During this time, scientists identified the age where people face menopause.

Scientists said that people aged 51 years or older than a 35 -year -old person are about 34 percent less likely to conceive.
