Sperm adversely affected by environmental factors
A new study indicates that the amount of time men spend driving and the frequency with which they engage in sexual intercourse impact seminal parameters.
Denver-A new study indicates that the amount of time men spend driving and the frequency with which they engage in sexual intercourse impact seminal parameters.
Researchers from Fertilidad San Isidro, a private, university-affiliated clinic in Buenos Aires, Argentina, undertook the study to develop a statistical model that could predict the impact of various lifestyle and environmental factors on semen production and quality, with the goal of changing harmful factors wherever possible, said senior author Claudio Ruhlmann, MD, medical director of Fertilidad San Isidro.
To that end, the researchers enrolled 128 men who had undergone at least two spermograms at Fertilidad San Isidro between June 2008 and June 2009. The investigators then evaluated the interaction of each environmental parameter on sperm quality in general. Additionally, multiple linear regression enabled them to assess which seminal parameters each environmental variable altered.
From evidence to practice: Dr. Makarov discusses implementation science in urology
July 25th 2024“What our major contribution is, I think as urologists doing implementation science, is determining the important questions, which we are particularly well-suited to do because we're taking care of the patients,” says Danil V. Makarov, MD, MHS.
