Omega-3 Intake Improves Clinical Pregnancy Rate in Polycystic Ovary Syndrome Patients: A Double-Blind, Randomized...

Area of Science:

• Reproductive Endocrinology
• Nutritional Science

Background:

• Omega-3 fatty acids are crucial for reproductive health and fetal development.
• Polycystic Ovary Syndrome (PCOS) is a common cause of infertility in women.

Purpose of the Study:

• To evaluate the efficacy of omega-3 fatty acid supplementation during ovulation induction in women with PCOS-related infertility.
• To determine if omega-3s improve conception rates in this patient population.

Main Methods:

• A randomized, double-blind, placebo-controlled study involving 34 women with PCOS undergoing ovulation induction with clomiphene citrate.
• Participants received either omega-3 supplements (3 × 600 mg/day) or placebo for up to two cycles.
• Data collected included hormonal levels, ultrasound findings, and clinical pregnancy rates.

Main Results:

• Clinical pregnancy rates were higher in the omega-3 group (26.7%) compared to placebo (13.3%).
• Among overweight/obese women (BMI 25-35), omega-3 supplementation significantly increased clinical pregnancies (29.6% vs. 5.3%, P < 0.04).
• Higher omega-3 intake, lower BMI, and increased endometrial thickness were associated with higher pregnancy odds in overweight/obese PCOS patients.

Conclusions:

• Omega-3 fatty acid supplementation shows a beneficial effect on fertility in women with PCOS.
• The positive impact of omega-3s on fertility is particularly significant for overweight and obese women with PCOS.
