semen analysis (abnormal pH)
Last reviewed 01/2018
An abnormally low pH i.e. less than 7.0 may indicate retrograde ejaculation when combined with a very low ejaculate volume. A pH of below 7.0, normal volume and azoospermia may indicate an obstruction of the ejaculatory ducts or congenital bilateral absence of the vas.
An abnormally high pH i.e. greater than 8.5 may indicate an infection or dysfunction of one of the accessory glands.
