Abstinence 'reduces sperm strength' - Telegraph

Sunday 25 August UK News feed. Men who abstain from sex in the belief that they are enhancing their fertility could be damaging their chances of having a child, according to new research. The study found that the benefits of abstention in increasing a man's sperm count were more than cancelled out by a decline in semen motility, or ability to swim up to an egg and fertilise it. At present, couples who are having difficulty conceiving are often advised not to have sex for up to a week in order to increase the quantity of sperm in time for the fertile peak of the woman's reproductive cycle. He said some men might be told that they have poor sperm quality because they had abstained from sex before they were tested.

Abstinence 'reduces sperm strength'

Log in Advanced Search. Sperm quality and pregnancy outcomes in IVF may be improved with frequent ejaculation, a new study suggests. Research carried out at the Centre for Reproductive Medicine in Shenyang, China, aimed to determine the effects of a short period of abstinence on the quality of ejaculated sperm, as well as its effect on the pregnancy outcomes of couples undergoing IVF. Major molecular differences were seen between samples of semen depending on the duration of abstinence. Specifically, semen samples collected after only one to three hours of abstinence contained more motile sperm with a higher reproductive potential than samples collected after men had abstained for three to seven days.

The aim of this study was to evaluate the influence of different periods of abstinence on conventional semen parameters as well as functional parameters in human semen, including mitochondrial function, chromatin packing and sperm DNA fragmentation. We recruited a cohort of 2, men undergoing infertility investigation. Associations between the sexual abstinence period and sperm parameters were assessed using Spearman correlation. The duration of abstinence had a statistically significant positive influence on sperm concentration and volume, the number of leukocytes and a statistically significant negative influence on sperm motility and vitality. The percentage of sperm protamination was statistically significantly increased with abstinence.
