The effect of consecutive ejaculation on the sperm parameters in the oligo-astheno-teratozoospermia (OAT) men.

Recently, the World Health Organization recommendation for abstinence time for semen analysis has been challenged in some studies and many of them have supported the advantages of a second short abstinence ejaculation. More evidence is needed to approve this for clinical use. This study aimed to compare the average routine abstinence time (2-7 days) with the short time (1-2 h) on sperm quality based on functional parameters in a population of oligo-astheno-teratozoospermia (OAT) men.

Umbilical cord blood thyroid hormones are inversely related to telomere length and mitochondrial DNA copy number.

Hypothyroidism has been linked to reduced mortality rate and increased lifespan and health span.

It was proposed that the status of these markers in early life can be predictive of lifespan and the predisposition to certain age-associated disease in adulthood.
