In Phase II, participants in Group A received a pill of placebo and then received a pill of sildenafil after the washout period; and participants in group B received sildenafil and then received a placebo after the washout period. The mean age of patients was 34 ± 5 years. There was no significant difference in the mean sperm count before receiving the drug in all groups. Sperm count, motility, morphology, pH, viscosity, and liquefaction time of semen did not significantly change after receiving sildenafil in comparison to their corresponding placebo group (P > 0.05).

It might be beneficial in patients with diabetes, ischemic heart diseases, peripheral vascular diseases, hypertension, depression, and kidney diseases. [8,9] This drug stimulates Leydig cell secretory function and also enhances prostatic secretory function. It also increases citrate and cholesterol concentrations in the semen, which may preserve the natural morphology of the sperm against osmotic shock and environmental stress. Moreover, studies have indicated that sildenafil increases sperm motility. [10,11] Hence, sildenafil has a beneficial effect on male infertility.

Does sildenafil interact with other medicines (drug interactions)?

The evidence reveals that sildenafil administration might have beneficial effects on many sperm parameters, such as sperm count, sperm motility, sperm morphology, semen volume, seminal fructose concentrations, and semen acidity. [12,13,14] It has been confirmed that the cyclic AMP, adenosine 3',5'-cyclic monophosphate (cAMP) concentrations, sperm motility, sperm activity, sperm production, sperm quality, and phosphorylation of tyrosine proteins would be increased after inhibition of PDE by sildenafil. [14,15] However, some controversies exist concerning the effects of sildenafil on sperm motility. [16,17] Studies have shown that the effects of sildenafil on sperm motility are dependent on its concentration. [13] It seems that sperm motility would be increased in lower plasma sildenafil concentrations, and it would be decreased in higher plasma sildenafil concentrations.

[18] This randomized, double-blind, controlled cross-over clinical trial study was conducted to evaluate the effects of oral sildenafil on semen parameters in male participants with idiopathic infertility. This randomized, double-blind, placebo-controlled, cross-over clinical trial study was conducted in accordance with ethical guidelines and the Declaration of Helsinki and approved by the urology research center and the Ethics Committee. A total of 79 participants had been referred to the urology clinics in Rasht. Participants with idiopathic infertility in the age range of 25–40 years with normal arousal function were included in the study. Idiopathic infertility is defined as the lack of an obvious cause for couples' infertility and women's inability to get pregnant after at least 12 cycles of unprotected intercourse or after six cycles in women aged > 35 years for whom all standard evaluations are normal. Sildenafil did not change sperm parameters in treating infertile patients; sildenafil also had no positive effect on semen parameters. Infertility is a common problem that may affect couples; currently, most of them are seeking medical treatment. Infertility in men is a personal and social problem, and it is clear that it should be treated by safe and effective drugs. [1,2] Conversely, sexual dysfunction is one of the common complications in more than 50% of men aged 50–70 years.

5.3 Epistaxis

Unexplained infertility is a condition when standard infertility testing has not found a cause for a couple's or a woman's inability to get pregnant. Some reproductive physicians hold that a diagnosis of unexplained infertility is a nondiagnosis. [3,4] Sexual dysfunction could have negative effects on the quality of life of both youth and elderly individuals. Sildenafil is identified as a potent and selective phosphodiesterase Type 5 (PDE5) inhibitor. Presently, sildenafil is considered not only as a treatment of erectile dysfunction (ED) but also as a potential treatment option for tablet sildenafil 50 mg male idiopathic infertility. [6,7] It is able to significantly prolong the stiffness duration.
