An abnormal semen pH indicates the other than normal pH of human semen that has a range of 7. Pure water is neutral, at pH 7, being neither an acid nor a base. Solutions with a pH less than 7 are acidic and solutions with a pH greater than 7 are basic. The balance between the alkaline secretion of the seminal vesicles and the acidic prostatic secretion determines the semen pH.
The Semen pH Affects Sperm Motility and Capacitation
The pH scale ranges from zero highly acidic to 14 very basic. A pH of seven is considered neutral, so pH regulation for pregnant women is extremely important. Most people suffering imbalanced pH levels zero to five are too acidic. Mild to moderate acidosis may promote high blood pressure, heart problems, osteoporosis, diabetes, obesity, and kidney stones. Hormone production in both men and women can be affected by mild acidosis since the ovaries and testes are losing minerals due to acidic pH.
A semen analysis plural: semen analyses , also called seminogram , or spermiogram   evaluates certain characteristics of a male's semen and the sperm contained therein. It is done to help evaluate male fertility , whether for those seeking pregnancy or verifying the success of vasectomy. Depending on the measurement method, just a few characteristics may be evaluated such as with a home kit or many characteristics may be evaluated generally by a diagnostic laboratory. Collection techniques and precise measurement method may influence results. Semen analysis is a complex test that should be performed in andrology laboratories by experienced technicians with quality control and validation of test systems.

As the chemical environment of semen can have a profound effect on sperm quality, we examined the effect of pH on the motility, viability and capacitation of human sperm. The sperm in this study was collected from healthy males to avoid interference from other factors.
