I am a 50-year-old man. Is it natural for my ejaculation volume to diminish with age? Will this have any effect on my fertility?

The majority of the ejaculate volume is fluid from the prostate and the seminal vesicles. Occasionally, a dramatic decrease in ejaculate volume may indicate blockage of one of the ejaculatory ducts. Duct obstruction is diagnosed by prostate ultrasound. Other possible causes of decreased volume include retrograde ejaculation or a long-term infection of the prostate (chronic prostatitis).

Decreased semen volume may simply be a normal part of aging and may not necessarily result in decreased fertility. A semen analysis will help your physician determine whether you need additional testing.
