[Evaluation of long-term results of using the drug Fertiwell: impact on the likelihood of conception and pregnancy outcome].

Introduction: Current methods of treating male infertility have limited efficiency, since they are aimed to individual stages of the pathogenesis. Preparations based on testicular regulatory polypeptides are the most physiological and universal, owing to a complex effect on the self-regulation of testicular tissue.

Aim: To study the delayed efficiency and safety of therapy with Fertiwell in patients with pathospermia and to assess the frequency of conception and pregnancy outcome in their partners based on the collection, analysis and interpretation of medical data.

Materials And Methods: A telephone survey of patients participating in the phase III clinical trial was carried out. The fact of conception in a couple was assessed over a period of 1 to 9 months after completion of therapy, as well as time from completion of the course to conception, pregnancy outcomes, newborn health outcomes.

Results: In the period from 1 to 9 months after completion of therapy, pregnancy occurred in 17 out of 34 couples (50%) in the Fertiwell group and in 13 out of 42 couples (30.95%) in the placebo group. This difference was statistically and clinically significant (p<0.05). All pregnancies resulted in a live birth. The median time from completion of the course to conception was 4 months in Fertiwell group and 6 months in the placebo group. There were no significant differences in anthropometric parameters of newborns between the two groups (p>0.05).

Conclusion: When using the drug Fertiwell, pregnancy and live birth rate was significantly higher (2.23 times) compared to the control group. There was a trend toward earlier pregnancies in partners of men receiving Fertiwell. Thus, this drug can be recommended for the treatment of men with idiopathic infertility as monotherapy, as well as in combination with assisted reproductive technologies.
