OBJECTIVE
To evaluate the effectiveness of rectal administration of zinc arginyl glycinate dihydrochloride (ZAG) at a dose of 16 mg/kg in an experimental model of male infertility (pathozoospermia) and compare the results obtained with the currently available data from clinical trials.
MATERIAL AND METHODS
The study used 30 outbred male Wistar rats, sexually mature (11 weeks), divided into 3 groups. The experimental group was injected with ZAG at a dose of 16 mg/kg, the background group consisted of intact animals, the control group received suppositories that did not contain an active substance (placebo). The test substances were administered rectally in the form of gelatin suppositories once a day, every day for 5 days before and 5 days after the administration of the etoposide (30 mg/kg) that simulates the pathology. A day after the last injection, indicators characterizing the morphofunctional state of male germ cells were determined.
RESULTS
The pharmacological activity of the ZAG preparation was revealed in the experiment with oligo-, astheno- and teratozoospermia, which was characterized by a high degree of effect, the differences were statistically significant compared with the background and control groups.
CONCLUSIONS
The obtained experimental data on ZAG activity correspond to the results of clinical studies of the drug Prostatilen AC, one of the active substances of which is the investigated complex, which has proven its effectiveness in real clinical practice in the treatment of patients with chronic prostatitis and impaired fertility, what makes it possible to recommend the use of this substance in andrological practice as part of combined drugs for the treatment of various types of pathospermia.
