Putting down weight for an obese women desperate to become mother may increase sexual appetite but there is no role of weight loss in stimulation of ovulation, says researchers.
A group of researchers from Penn State College of Medicine recently made a study on how weight-loss surgery affected reproductive system in a group of vitiated obese women.
"Obesity in women has been linked to lack of ovulation and thus infertility," the Daily Mail quoted study leader Dr Richard Legro as saying.
"Obesity, especially centred in the abdomen, among infertile women seeking pregnancy is also associated with poor response to ovulation induction and with decreased pregnancy rates," he said.
During the study, the team took the samples of the participants urine to measure ovarian hormones during the course of a menstrual cycle found surprisingly results that ovulation rates remained high among the 29 women taking part in the study.
They remained at more than 90 percent at all time points before surgery and up to two years afterwards.
Moreover, the quality of the ovulation also remained same. The only change that was observed was a reduction of time of the first half of the menstrual cycle, from the end of the previous menstrual flows until the release of the egg.
However, questionnaires filled in by the participants revealed with an interesting fact that losing the weight had a significant impact on libido, with increased level of sexual desire and arousal. The researchers said this may have pushed the women to have sex more often.
"The effects of weight loss on reproductive function are more modest than we hypothesized. In terms of ovulation, there doesn't appear to be a window after surgery where fertility is improved," Dr Legro said.
"The door appears to be open at all times. Other factors may be involved with
infertility in obese women, such as diminished sexual desire and thus less
intercourse," he said.
The details of the study have been published in the Journal of Clinical
Endocrinology and Metabolism.
