The results from 225 men attending an infertility clinic are presented. The percentage of oval, viable and active sperm cells, and the motility scores were lower in samples with counts less than 10 times 10(6) per ml., increased in counts or 10 to 40 times 10(6) per ml. and again increased in counts more than 40 times 10(6) per ml. The percentage of semen samples with abnormalities in measured parameters dramatically increased as the sperm count decreased. The percentage of samples with significant numbers of white blood cells was higher in samples with sperm counts less than 10 times 10(6) per ml. and in the azoospermic patients, while viscosity problems seemed to be associated with counts less than 10 times 10(6) per ml. Agglutination was more of a problem in samples with counts more than 40 times 10(6) per ml.
The effect of the prostaglandin synthetase inhibitor, indomethacin on urodynamic values measured by radionuclide imaging was studied in 17 men in a double-blind placebo controlled randomized trial. Measurements were made of voiding time, time for 50% emptying, average flow rate, ejection fraction, post-void residual urine volume, voided volume, and total bladder volume. Statistical analyses indicated no placebo-indomethacin differences between the two groups. Although prostaglandins are thought to contribute to the act of micturition by maintenance of bladder tone and contractility, our studies indicate that a standard dose of the prostaglandin inhibitor, indomethacin, did not affect the voiding component of bladder function. Patients need not discontinue prostaglandin inhibitors and other non-steroidal anti-inflammatory drugs with such effects prior to urodynamic testing.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
