Could doctors at fertility clinics be giving men bad advice? Dr. Da Li and Dr. XiuXia Wang, who are clinician-researchers at the Center for Reproductive Medicine of Shengjing Hospital in Shenyang in northeast China, think so. Recent research from Li’s and Wang’s lab, published in the journal Molecular and Cellular Proteomics, upends conventional wisdom that […]Continue Reading ...
Nearly one in eight couples in the U.S. face infertility, and about half of those cases can be attributed to semen abnormalities in the male partner. As the root causes often remain a mystery, new research into the basic biology behind sperm development could one day lead to renewed hope for those wanting to grow […]Continue Reading ...

A new study at The University of Toledo shows that a father donates not one, but two centrioles through the sperm during […]Continue Reading ...
May 11, 2018 The group led by ICREA Research Professor Cayetano Gonzalez at the Institute for Research in Biomedicine (IRB Barcelona), in collaboration with Giuliano Callaini’s team at the University of Siena in Italy, has published a study in The Journal of Cell Biology that identifies the critical role played by a protein called CENTROBIN […]Continue Reading ...
For couples hoping for a baby via in vitro fertilization, chances have improved. A process that once took hours now takes minutes: Cornell University scientists have created a microfluidic device that quickly corrals strong and speedy sperm viable for fertilization. Conventional methods to separate vigorous, motile sperm is tedious and may take up to several […]Continue Reading ...
August 17, 2018 In a study published in Behavioral Ecology researchers from Uppsala University show that the same type of sperm is not always the best for all male birds. Depending on how attractive or dominant you are you might be more successful with longer or shorter sperm. Getting a big family can be a […]Continue Reading ...
By Kate Bass BScJuly 26, 2018 New research indicates that small RNA in sperm controls the development of an embryo and is necessary for successful embryo implantation in the uterus. These findings have important implications for optimising fertility treatments.

By Dr Ananya Mandal, MDJuly 4, 2018 A new study has shown that including nuts in daily diet could significantly improve the quality as well as function of the human sperm. Nuts are part of the Mediterranean diet that is considered to be the healthiest diet for the heart, blood vessels and other organs. Image […]Continue Reading ...
By Sally Robertson, BScJuly 2, 2018 A large clinical trial conducted in the U.S. has shown that daily antioxidant supplementation among men with infertility does not make a difference to the quality of their sperm. Image Credit: Supitcha McAdam / Shutterstock Although previous studies have suggested that taking antioxidants improves abnormal sperm parameters, the current […]Continue Reading ...
June 7, 2018 Prolonged stress, such as that experienced during military conflict, can have an adverse impact on sperm quality, according to a new study by researchers at Ben-Gurion University of the Negev (BGU) and Soroka University Medical Center in Beer-Sheva, Israel. The study, which was just presented at the International Summit on Assisted Reproduction […]Continue Reading ...
May 11, 2018 Sperm are highly specialized cells adapted to achieve a single goal: fertilize an egg. Along the road to fertilization sperm must embark on a lengthy journey to the female oviduct, avoiding several fatal stresses that occur when they pass through different physiological environments. However, the events that allow sperm cells to achieve […]Continue Reading ...
