Dietary patterns, foods and nutrients in male fertility parameters and fecundability: a systematic review of observational studies

Abstract

Male adherence to a healthy diet could improve semen quality and fecundability rates. Since observational studies may prove associations but not causation, the associations summarized in the present review need to be confirmed with large prospective cohort studies and especially with well-designed RCTs.

Lack of a meaningful association between dietary patterns and in vitro fertilization outcome among Japanese women

“…Third, we did not examine the influence of paternal factors, such as diet and lifestyle. There are some reports suggesting that a healthy diet can improve semen quality and fecundability rates in men . Fourth, we obtained information about folate supplement usage but not about its dosage.…”

The Effects of Omega3 on Oocyte Maturation

“…Generally, the results indicated that healthy diets rich in some nutrients such as omega-3 fatty acids, some antioxidants (vitamin E, vitamin C, β-carotene, selenium, zinc, cryptoxanthin and lycopene), other vitamins (vitamin D and folate) and low in saturated fatty acids and trans -fatty acids were associated with improved reproductive system function. [5] Supplements that have demonstrated positive effects on fertility include aescin, coenzyme Q 10 , glutathione, Korean red ginseng, L-carnitine,…”

Antioxidant Therapy Is the Key to the Treatment of Idiopathic Male Infertility

“…Существует более 25 селенопротеи-нов, таких как гидропероксид фосфолипида ГТП и спер-матозоидный селенопротеин супероксид ГТП, которые помогают поддерживать структурную целостность спер-матозоидов. Морфологические аномалии и нарушение подвижности сперматозоидов являются одними из наи-более распространенных видов патоспермии, связанных с дефицитом селена [18].…”
