Research from Dr. Michael Golding’s laboratory at Texas A&M University indicates that male alcohol use has a significant negative influence on in vitro fertilization (IVF) success rates, thus increasing patient financial burden and emotional stress.
The recently published work is part of Golding’s research program focused on understanding how male drinking prior to conception contributes to the development of alcohol-induced birth defects and disease. This particular study highlights the importance of expanding fertility and pre-pregnancy messaging to emphasize the reproductive danger of alcohol use by both parents, not just the mother.
These statistics highlight the growing importance of looking at both parent’s contributions to fertility and pregnancy outcomes, according to Golding, an associate professor in the School of Veterinary Medicine & Biomedical Sciences’ Department of Veterinary Physiology & Pharmacology.
“We say to the woman, ‘you need to be careful of what you eat. You need to stop smoking. You need to be doing all these different things to improve fertility,’” Golding said. “We don't say anything to the man, and that's a mistake, because what we're seeing here is that the couple’s odds of success with their IVF procedure are increasing simply by addressing both parents’ health habits.”
Golding’s research used a mouse model to determine the effects of a potential father’s drinking on IVF pregnancy outcomes. The model included a control group that represented males who do not drink, a group that represented males who participate in chronic drinking at the legal limit, and a group that represented males who participate in chronic drinking at one and a half times the legal limit.
The results of the research revealed that the more a male drinks before providing sperm for an IVF pregnancy, the less likely the pregnancy is to be successful.
“The most important aspect of this research is that it makes it clear that everybody plays a role in achieving successful pregnancy outcomes, even though the general assumption is that it’s just women,” Roach said. “The most important thing to take away from this is that if you’re a male considering having a family, abstain from alcohol until your wife gets pregnant.”
The research concludes that male alcohol use hinders an embryo's ability to successfully implant in the uterus and reduces IVF embryo survival rates. The research also revealed more questions about fetal development and paternal drinking. Golding’s lab is continuing to research these questions and the paternal aspects of fetal alcohol spectrum disorders, a group of conditions that can occur when a person is exposed to alcohol before birth. His work aims to provide a holistic look at understanding fetal development and pregnancy by examining the father’s role in it.
“It is important to remember that couples struggling with fertility who have chosen to pursue IVF are under intense emotional and financial pressure, which is associated with a feeling of helplessness,” Golding pointed out. “Our study demonstrates that drinking alcohol is an unrecognized factor that negatively impacts IVF pregnancy success rates. Therefore, as alcohol use is easily changed, our study identifies a shared action item that can empower the couple to work together toward their goal of becoming pregnant.”
