Infertility Drugs Requires Beta Estrogen Receptor ß Gene at The Biotech Weblog

While it doesn't provide answers as to how infertility in women may be reversed, results form a recent study offers an explanation why infertility drugs may not work in some women. In the August issue of Endocrinology, researchers report that in mice that were genetically engineered to lack estrogen receptor beta, fertility drugs did not improve ovulation rates. "If the results from this animal study are found to be applicable to [...] Read More


Gene Mutation Causing Infertility in Male Mice at The Biotech Weblog

Cornell University researchers have identified a mutation in a gene in mice that causes male infertility. The gene, called Dmc1, provides the code for a key protein involved in meiosis, the process that produces sperm and egg cells for reproduction. These sex cells contain only one set of chromosomes that combine during conception and create an embryonic cell with two chromosome sets, one from each parent. The Dmc1 mutation causes a [...] Read More
