A team of researchers has demonstrated how a non-invasive ultrasound technique can increase the movement of human sperm in the laboratory by up to 266%. Using microfluidic droplets to evaluate individual sperm cells, which had not been done before, they found that ultrasound exposure induced movement in immobile sperm and improved swimming speeds in mobile ones. The work is published today in the journal Science Advances.


Two decades of research has found no differences in psychological well-being and the quality of family relationships between children born through assisted reproduction with third-party intervention (gamete donation or surrogacy) and those born naturally. The results, published in Developmental Psychology, suggest that it is better to talk to them early, at preschool age, about their biological origins.


A sperm donor in the Netherlands has allegedly fathered more than 550 children in at least 13 clinics in the Netherlands and other countries. One of the mothers of these children and the Donorkind Foundation (Netherlands) have sued him. In Spain, there is a national registry of gamete and pre-embryo donors, and the law on assisted human reproduction techniques does not allow more than six babies to be born from the same donor.
