Acid phosphatase activity in human uterine fluid in relation to infertility.

In the luminal fluid of parous women the acid phosphatase activity was found to be very low and remained virtually unchanged throughout the cycle (10.60 to 18.14 mgp/hr/100 ml). In the infertiles, the activity was generally high with a maximum of 54.37 mgp/hr/100 ml at late follicular phase. It was argued that increased enzyme level in infertiles could have adversely affected the sperm capacitation power as well as the implantation of the fertilized ovum.
