A new study from researchers at the University of Melbourne, adds to the numerous motivations for obese men to lose weight. The study points to obesity as having a negative impact on sperm, leading to lower rates of conception, smaller fetuses, and reduced placental weight. (The placenta is important to not only the health of the developing fetus, but has long term implications affecting health conditions throughout the entire lifespan of a person.)
The researchers studied mice, and saw that the rate of the embryo successfully implantating in the womb decreased in obese mice by up to 15 percent, compared to mice of normal weight. Additionally, the weight of the placenta and fetal development were significantly less for embryos created with the sperm of obese males. Dr. Tom Brown, weight loss surgeon in Colorado, commented that “when obese patients achieve weight loss, we see improvements in overall health, so it is likely that reproductive health would also be favorably impacted, as this study suggests.”
Another recent study found that weight loss improves libido in men. The findings indicated that sexual desire, erectile function and urinary symptoms all significantly improved in 31 obese patients who lost 5—10 percent of their body weight over an 8 week period. The findings were published last year in the Journal of Sexual Medicine. In the United States, more than one third of men are obese (defined as Body Mass Index of 30 or greater), so findings such as these can have significant effect for many men.
Research has demonstrated that weight loss surgery, such as the lap-band procedure, leads to significant weight loss, as well as the longest period of sustained weight loss in obese patients.
