| dc.description.abstract | The prevalence of obesity, one of the most common health problems in the world, has
shown an increase in the recent years. Obesity has detrimental effects on the reproductive system.
Furthermore, infertility is more common in obese patients. Weight loss has been found to have
positive effects on the reproductive system of these patients. Although the reason is not clearly
known, a decrease in the amount of fat, affects fertility in a positive way, as a consequence of normalization of the hormonal balance and sexual activity. Among the weight-loss strategies, caloric
restrictions and exercise constitute the first step. However, certain surgical procedures called
bariatric surgeries are also performed on some obese patients, for contributing to weight loss. Till
date, many bariatric surgical procedures have been defined, which can be classified as malabsorptive, restrictive, and combined procedures. The effect of various surgical techniques on the fertility in patients treated with bariatric surgery is still controversial. A multicentric study had stated
that there is no difference between restrictive and malabsorptive bariatric surgery techniques. Obesity has been shown to have serious potential effects on the male and female fertility factors. Semen
parameters investigated as factors associated with obesity include, sperm concentration, number
and motility. In some recent studies, it has been reported that increased BMI could lead to infertility by disrupting the hormonal profile and/or causing DNA damage in the sperm. Studies have also
reported that obese men treated with bariatric surgery showed significantly decreased estrogen levels, while having appreciably increased testosterone, SHBG and FSH levels, and improved sexual
functions. To conclude, obesity is a factor that reduces the fertility potential in both, men and
women. While dealing with obesity, dietary habits should be regulated and physical activity should
be increased at first. Bariatric surgery should | en_US |
