Certain Nutritional Supplements May Help Improve Sperm Health

Approximately 40-50% of infertility cases worldwide are due to male factor infertility. A new study has found that nutritional supplements such as CoQ10 and L-carnitine may help improve sperm quality.


The researchers included 61 studies in their review. All the studies tested a range of drugs and supplements for improving semen qualities and chances of a live birth. The researchers focused on data that related to sperm motility, sperm count, and sperm size and shape.


The researchers found that pentoxyfylline, CoQ10, L-carnitine, follicle-stimulating hormone, tamoxifen, and kallikreinCoQ10 resulted in improvements in sperm parameters. CoQ10 was found to be linked to sperm count, motility, and shape in three of the four studies that continued for three to six months. However, the researchers classified the quality of evidence as low. The researchers also found that L-carnitine seemed to improve sperm numbers and motility, while sperm size and shape remained unchanged.


The study was conducted by researchers from the University of Aberdeen. It was published in the April, 2019 issue of European Urology.
