A way of using nanoparticles to investigate the mechanisms underlying infertility has been developed by British scientists, according to a new report published in a scientific journal on Friday. The technique, published in Nanomedicine: Nanotechnology, Biology and Medicine, could help researchers discover the causes behind cases of unexplained infertility, and develop treatments for affected couples. The method involves loading porous silica nanoparticle "envelopes" with compounds to identify, diagnose or treat the causes of infertility. Researchers demonstrated that the nanoparticles could be attached to boar sperm with no detrimental effects on their function. "An attractive feature of nanoparticles is that they are like an empty envelope that can be loaded with a variety of compounds and inserted into cells," Natalia Barkalina, lead author of the study from Oxford University, said. "The nanoparticles we use don't appear to interfere with the sperm, making them a perfect delivery vessel." According to researchers, sperm are difficult to study due to their small size, unusual shape and short lifetime outside of the body, yet this is a vital part of infertility research. Previous methods involved complicated procedures in animals and introduced months of delays before the sperm could be used. The new technique enabled researchers to expose sperm to nanoparticles in a petri dish, which can all be done quickly enough for the sperm to survive perfectly unharmed. "We will start with compounds to investigate the biology of infertility, and within a few years may be able to explain or even diagnose rare cases in patients. In future we could even deliver treatments in a similar way," study co-author Celine Jones said.
