Three ways obesity affects your sperm and what you can do about it.
Although the semen analysis has been the standard test of male fertility for over 50 years it cannot accurately establish whether a man is fertile or infertile.
Semen is composed of sperm made in the testicles and fluid from nearby glands. The semen analysis is a microscopic exam of semen obtained by masturbation after a 2-5 day abstinence period. It measures the volume of semen, and the sperm count, swimming ability (motility) and shape (morphology) based on criteria set by the World Health Organization.
Although the semen analysis has been used for decades as a general indicator of male reproductive health, it cannot accurately establish whether a man is fertile or infertile.
Abnormal sperm tests should never be ignored as they may indicate other medical conditions such as cancer or metabolic and cardiovascular disease.
Sperm DNA Fragmentation Test
Sperm DNA must be intact to function properly. The Sperm DNA Fragmentation Test determines the percentage of broken (fragmented) DNA within the sperm. DNA fragmentation is associated with lower pregnancy rates but only if the percentage of fragmentation is high. The test is not recommended by the American Society for Reproductive Medicine since it does not predict treatment outcomes for most men.
