Linoleic acid (LA) is an essential omega-6 polyunsaturated fatty acid found in many vegetable oils, nuts, and seeds. Its role in the female reproductive system has some scientific basis, though evidence is moderate. LA is a precursor for important bioactive lipids, such as prostaglandins, which are involved in the regulation of the menstrual cycle, ovulation, and uterine function. Some studies have suggested that a balanced intake of omega-6 and omega-3 fatty acids may positively affect reproductive health, possibly by supporting normal hormonal function and reducing inflammation that can impact fertility.

However, the evidence is not robust. Most human studies focus on overall dietary patterns rather than isolated supplementation of linoleic acid. Some animal studies indicate that both deficiencies and excessive intakes of LA can negatively impact ovarian function and fertility. Additionally, epidemiological data suggest that essential fatty acids, including LA, are necessary for normal menstrual function and fetal development during pregnancy.

Despite these findings, there is limited direct clinical trial evidence demonstrating that supplemental linoleic acid alone improves any specific aspect of female reproductive health. The current scientific consensus supports adequate intake of LA as part of a balanced diet, rather than high-dose supplementation specifically for reproductive purposes. Thus, while there is some scientific rationale for its role in reproductive health, the evidence for targeted supplementation is limited.
