Can Selen help with fertility?

Selenium is an essential trace element important for thyroid function and antioxidant defense, both of which can influence fertility. Studies suggest that selenium deficiency may be linked to reduced sperm quality and increased miscarriage risk. However, the evidence is moderate: most data come from observational studies, and large randomized controlled trials are lacking. Supplementation beyond the recommended intake (e.g., >200 µg/day) can be toxic and may increase the risk of type 2 diabetes. MyBody-X does not offer a specific selenium test; the DNA and microbiome tests in the provided context contain no validated markers for selenium status or fertility. Therefore, individual medical advice is recommended before supplementing. Overall, selenium may help in cases of confirmed deficiency, but a general recommendation for fertility enhancement is not evidence-based.
