Delaying ovarian aging


In animal models, higher dietary omega-3 polyunsaturated fatty acids extend reproductive lifespan. In women with normal weight (but not in obese women) with normal ovarian reserve, dietary administration of 4 g/day of EPA + DHA decreases serum follicle-stimulating hormone (FSH) levels. In women, FSH helps control the production of eggs by the ovaries and the menstrual cycle (in men, FSH helps control the production of sperm).

Ovarian reserve is the pool of eggs present in the ovaries at any given time. At birth, women have one to two million eggs; at puberty, from 250,000 to 500,000 eggs; at 37 years of age, a woman will only have approximately 25,000 eggs and at menopause less than 1000. We (they!) talk about low ovarian reserve when there is a decrease in the number of eggs, an insufficient number to ensure a reasonable chance of pregnancy.

Supplementation with omega-3 could be useful in women with diminished ovarian reserve in order to delay ovarian aging.
