Recurrent miscarriage is typically defined as the loss of three or more pregnancies in a row. As the mother carries the pregnancy, the traditional belief has been that the underlying cause of miscarriage resides with her. But maternal factors such as hormone imbalance or an inability for the womb to support the pregnancy only account for about half of recurrent miscarriages. Before becoming pregnant, many women will assess and modify their current lifestyle choices, for example drinking or smoking less, in order to ensure a healthy pregnancy.

Release Date: January 21, Burkman is assistant professor and head of the Section on Andrology in the Department of Gynecology and Obstetrics in the UB School of Medicine and Biomedical Sciences, and assistant professor of urology. Based on these results, Burkman's research group is preparing to conduct the first study of nicotine's effect on specific sperm functions in semen samples taken from a group of male smokers who agree to stop smoking. Sperm samples will be collected before and after the men quit. The study is expected to get underway in June. Nicotine also binds to receptors for acetylcholine, an important neurotransmitter. Burkman's research also will help to determine how this action affects normal body functioning.

Tsukuba -- 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 fertilization under these conditions are only partially understood. In a study published in The FEBS Journal , researchers at the University of Tsukuba and Cornell University report they have uncovered a cell volume regulator in sperm cells that plays a key role in maintaining their shape and fertility. Most of a cell's mass consists of water, and this water can determine a cell's volume.
