There are several factors why one woman doesn't get pregnant. Some of the most common factors as explained by the Center for Women's Health are the tubal factor, the ovulation factor, the uterine factor, the peritoneal factor, and most especially the age factor.

Given these reasons, more and more women are now advised to have their egg cell frozen. By preserving their eggs, they are given more freedom to postpone their pregnancy no matter how long it would take and no matter what would happen to them.

But recently, experts found out that it's not just women who are up to preserving their reproductive cells, even men prefer to store their swimmers on ice. One of them is Gilbert Sanchez, a 25-year-old man who decided to freeze his sperm just before his birthday in a company named Legacy.

"It was a little bit weird," shares Sanchez. But despite being unused to it, he still pursued to take a chance since he knew he and his girlfriend won't settle soon. Besides, the processes "...was medically responsible", Sanchez added.

Sanchez, same with other men's decision of having their sperm frozen, was based on new research conducted, which showed how older men are at risk of producing offspring with abnormalities, autism, and schizophrenia. Furthermore, the research also revealed that the older the father is, the higher it is for their partner to be at risk of miscarriage too.

Legacy, one of the companies focused on helping men freeze their sperm, is now encouraging more men to consider sperm freezing. To them, their message is not just for those who are suffering from infertility, cancer, or other infertility issues, but also those who want to secure their family in the future. "I view this as an insurance policy for the future," explained the 30-year-old Legacy's CEO, Khaled Kteily, who's also their company's first client.

But despite the claims, experts say there is no need to rush. "If we're talking about someone in his 40s who think he is not going to have children until he is in his 60s, it's up for discussion", says Natan Bar-Chama, a male infertility specialist at Reproductive Medicine Associates of New York.

On the other hand, with men who are less than 40, experts say sperm freezing is unnecessary, especially to millennials. Tracey Woodruff, director of the Programme on Reproductive Health and the Environment at the University of California, San Francisco, claims what they should do is prevent the issue from taking place in the future.

There are several ways on how a man can avoid infertility, according to Mayo Clinic. Some of those are by avoiding the use of drugs and tobacco and by drinking alcoholic beverage moderately.
