Re: Men’s Meat Intake and Treatment Outcomes among Couples Undergoing Assisted Reproduction

MALE INFERTILITY
Abstract available at http://www.ncbi.nlm.nih.gov/pubmed/26253817 Editorial Comment: Concern is increasing that benzophenone chemicals used in some sunscreens may function as endocrine disruptors, mimicking estrogen function, and as a consequence impair sperm production. These investigators correlated urinary benzophenone concentrations to sperm parameters in a cohort of more than 400 men and observed diminished sperm parameters with 2 of the chemicals. Add sunscreens containing BP-2 (2,2ʹ,4,4ʹ-tetrahydroxybenzophenone) and BP-8 (2,2ʹ-dihydroxy-4-methoxybenzophenone) to the list of products that may harm male fertility. Craig Niederberger, MD

Abstract available at http://www.ncbi.nlm.nih.gov/pubmed/26206344 Editorial Comment: Men often ask what they can do to improve their reproductive health, especially regarding diet, and a number of studies have suggested that some foods may be better than others for male fertility. These investigators studied meat intake and observed that eating poultry was associated with improved fertilization in in vitro fertilization and intracytoplasmic sperm injection, and that processed meats were associated with worsened fertilization rates in conventional in vitro fertilization, although neither seemed to affect clinical pregnancies or live births. For now it would seem prudent to caution men that processed meats may be something to watch while undergoing assisted reproductive care in favor of chicken or unprocessed meats.
