Short-term use isn’t a problem. Long-term use however may come with lots of side effects.
Generally, when a couple is trying to have a baby, the focus is put on the woman’s health. But today, more and more, fertility specialists are learning that the male’s contribution is almost as important, and male health as a consequence just as impactful. Fifteen percent of couples globally wrestle with infertility. Among these, male infertility is solely responsible for about 20-30% of cases, while it contributes to 50% of them.
Scientists conceptualize a potential avenue of creating an embryo with only male cells.
Remember that Arnold Schwarzenegger movie Junior where he was pregnant? Though it seemed hilarious and over-the-top at the time, scientists are actually close to making such a thing possible, sort of. Researchers at the University of Bath in the UK have opened up the possibility of an embryo using only male cells. Working with mice, they made a pseudo-embryo called a “parthenogenote.” This was an embryo created without sperm. The feat is performed by fooling an egg cell into thinking it’s been fertilized. Usually, a parthenogenote dies off after a few days. But here, scientists were able to fertilize them with a sperm cell, and inject each embryo into a female mouse.
