Q: How long should we be abstinent before TTC in order to get a good sperm specimen?

A: Doctors have long suggested to be abstinent for 5-7 days prior to attempting to get pregnant, however, a recent study found the opposite.

Israeli researchers examined 9,489 semen samples. They found that in men with normal sperm count there was a significant decrease in sperm motility and morphology the longer he was abstinent.

The researchers suggested that men with male infertility collect the semen after no more than one day of abstinence and that longer abstinence would worsen the test results.
