Conceived and designed the experiments: JZ BY. 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. The spermatozoa cultured in sperm nutrition solution at pH 5. Our results showed that these parameters were similar in pH 7. Compared with that at pH 7.
Does Semen Upset Vaginal Flora? — Dr. Susie Gronski
When you have a baby on your mind, it can be especially frustrating to have only a few days each month to get pregnant. Too low or too high pH levels in our bodies are important and often overlooked factors when it comes to trying to conceive. Our reproductive system is built to create and sustain different pH levels throughout the cycle. Women are born with these healthy bacteria which are given to them by their mothers.
The Semen pH Affects Sperm Motility and Capacitation
Semen contains numerous substances that influence its smell, and your individual diet, hygiene, and sex life all play a part. Certain foods can give it a sweet scent and taste! But eating or drinking acidic substances can make your semen smell foul. Some infections and conditions can influence its odor, too.
Normal semen is slightly alkaline. Acidic conditions can lead to reduced sperm motility and viability. Secretions of the different glands of the male reproductive tract contain fluids of different pH. The portion of semen that originates in the seminal vesicles is basic; that of the prostate gland is acidic.
