Carotenes Improve the Quality of Semen

Carotenes, such as beta carotene, lutein, and lycopene, are fat-soluble antioxidants that protect multiple aspects of human health. A new study shows that beta carotene and lutein are associated with better sperm movement (quality). Lycopene intake is associated with better size and shape of the sperm (morphology). 
This study was conducted on university-age men, indicating that sperm quality in those who should have the best sperm quality is already in a state of decline even at a young age. This issue is even more important in older men, who most certainly have higher levels of sperm-related damage to DNA that can cause birth defects.
The quality of the epigenome of male sperm is vital to the future health of the child. Women have long recognized the need for important nutrients to ensure prenatal health. It is also important that men are in good health prior to conception. I have previously reported that folic acid and DHA are also linked to sperm health. 
Carotenes such as beta carotene and lycopene, when consumed as supplements, should always be from natural sources, which will clearly be stated on the label. Consumer beware, the great majority of beta carotene and lycopene in the market are chemically-derived synthetics. Natural-source carotenes contain many nutritional cofactors. High quality carotenes are actually easier to absorb than carotenes from the diet, as dietary carotenes must be digested from their fiber before they can be absorbed. While these are still good to have in your diet, supplemental natural carotenes are true superfoods.
