Post orgasmic urine analysis

A urine sample is checked after masturbation and orgasm to check for sperm in the bladder.

Some causes of male infertility such as Diabetes, neurological diseases, some types of medicine cause semen to reflux backwards into the urinary bladder during ejaculation instead of coming out through the water pipe.

This is called “retrograde ejaculation”, typically affected men present with dry or low volume ejaculate.
