Japanese scientists, through research into which round sperm cells were injected, managed to get 14 babies born to men previously considered infertile. Round spermatids are premature sperm without a head and tail that are removed from the testicles of men and injected into electrically stimulated eggs. The method aims to help infertile men to become parents.
The 14 babies were born to 12 men and their companions in Japan after participating in sessions where they received injections of sperm. This procedure was banned in the United Kingdom in the 1990s due to great concern regarding the development and health of the babies to be generated. In the UK after scientific evaluation it was found that 1% of British men are sterile and do not produce sperm. However, the Japanese study states that 30% of infertile men who do not produce sperm have rounded spermatids making them fully capable of becoming parents.
The 14 births accompanied by the research were considered successful and occurred after the injection of 76 eggs electrically stimulated with sperm taken from men aged 22 to 46 years.
Between 2011 and 2014 where births occurred, no baby showed any signs of physical and mental problems, let alone genetic disorders. According to the team of scientists at the Institute for Assisted Reproduction Technology in Fukuoka, Japan concluded that even though it is an effective technique, success rates are still lower than in performing ICSI. But it can be considered a last resort for men who do not produce sperm and still want to use their genetic material to produce a child.

My name is Dr. Alexis Hart I am 38 years old, I am the mother of 3 beautiful children! Different ages, different phases 16 years, 12 years and 7 years. In love with motherhood since always, I found it difficult to make my dreams come true, and also some more after I was already a mother.
Since I imagined myself as a mother, in my thoughts everything seemed to be much easier and simpler than it really was, I expected to get pregnant as soon as I wished, but it wasn’t that simple. The first pregnancy was smooth, but my daughter’s birth was very troubled. Joana was born in 2002 with a weight of 2930kg and 45cm, from a very peaceful cesarean delivery but she had already been born with congenital pneumonia due to a broken bag not treated with antibiotics even before delivery.
