Infertility and weight reduction: influence and outcome

Area of Science:

• Reproductive Endocrinology
• Obesity and Fertility
• Women's Health

Background:

• Obesity is a significant risk factor for infertility in women.
• High body mass index (BMI) negatively impacts conception rates and pregnancy outcomes.
• Lifestyle modifications are increasingly explored as a primary treatment for obesity-related infertility.

Purpose of the Study:

• To evaluate the impact of weight reduction on spontaneous conception rates in obese infertile women.
• To assess the efficacy of ovulation induction therapy in conjunction with weight loss for improving conception.
• To determine the effect of weight reduction on overall pregnancy outcomes, including miscarriage rates.

Main Methods:

• An observational experimental study was conducted with obese infertile women (BMI > 30 kg/m²).
• Participants underwent a 6-month lifestyle change program (diet and exercise), followed by a 6-month observation for spontaneous conception.
• Women who did not conceive were treated with ovulation induction (clomiphene citrate) for another 6 months, with continued monitoring through delivery.

Main Results:

• A mean decrease in BMI of 9.6 ± 1.23 kg/m² was observed.
• The spontaneous conception rate was 41.17% (n = 35).
• The miscarriage rate was 16.66% (n = 9).

Conclusions:

• Weight reduction is an effective strategy for enhancing spontaneous conception rates in obese infertile women.
• Combining weight loss with ovulation induction therapy further improves conception success.
• Achieving a healthy weight positively influences pregnancy outcomes, reducing miscarriage rates.
