Male-Factor Infertility
Are male fertility supplements the answer?
Nearly all of my clients seeking guidance on nutrition for fertility are Women. There are many potential female-related causes of infertility (PCOS, maternal age, uterine fibroids etc).
However, studies show that male-factor infertility accounts for up to 30% of cases.
Research also shows that male fertility has declined over the past few decades.
Should male fertility supplements become a standard of care?
A systematic scoping review by Tully et al (2024) brings evidence to show that:
* Many men do not prioritise making lifestyle changes when trying to conceive.
* Oral antioxidant supplementation, while potentially beneficial, has inadequate evidence for male-factor infertility.
* Healthier dietary patterns rich in anti-oxidants (such as the DASH diet) have more evidence than single or multi-ingredient supplements.
* The study concluded that Whole diets (DASH, Mediterranean diet) etc) are more likely to have greater impacts on male fertility than individual foods or nutrients.
Consulting with a Certified Fertility Dietitian can provide clarity on evidence-based ways to improve the diet and male-factor infertility.
