Fish Oil Helps PCOS and Reduces Testosterone

Fish Oil Helps PCOS and Reduces Testosterone
Fish oil may have a spectrum of benefits for women affected by polycystic ovarian syndrome (PCOS) who are trying to conceive. In 2014, an animal study (1) discovered that when animals with PCOS were supplemented with fish oil, and a reduced carbohydrate diet, ovarian antioxidant levels were higher which may positively influence egg quality. And hormonal markers of PCOS such as testosterone were more balanced. The study concluded:

"Results revealed that administration of omega-3 plus lower carbohydrate food significantly controlled   PCO syndrome and balanced FSH and testosterone."

Another study (2) examined the effect of fish oil supplementation in PCOS women. This study was a double-blind randomized clinical trial on 78 overweight/obese PCOS women with irregular menses who received either 3 grams of omega-3 fats/day or a placebo for 8 weeks.

After the treatment period, women who received omega-3 treatment had more regular menses (47.2% versus 22.9%), and testosterone levels were significantly lower.

"Omega-3 supplementation could reduce serum concentrations of testosterone and regulate menstrual cycle without significant effect on SHBG (sex-hormone binding globulin) and FAI (free androgen index)…"

Although more studies are needed, this research confirms other studies which suggest that the signs and symptoms of PCOS may be reduced when women take omega-3 fish oil on a daily basis. As potent anti-inflammatory agents, omega-3 fats may reduce both the overt and hidden signs and symptoms of PCOS, improving ovarian health, ovarian antioxidants and balancing hormones.
