This double-blind, randomized, four-period, two-way crossover study was conducted to evaluate the acute effects of oral sildenafil mg single dose on sperm motility, count, density, morphology and vitality as well as ejaculate volume and viscosity in healthy male subjects.

The concentrations of sildenafil and its primary circulating metabolite UK, were measured in ejaculate and compared with those in plasma. The study also included assessments of safety and tolerability. A total of 17 healthy male volunteers aged 19—34 years were randomized to receive a single mg dose of sildenafil for two periods and a single dose of placebo for two periods, with each period separated by a minimum of 5—7 days. Sperm and ejaculate properties were evaluated from semen samples taken at screening and 1.

An additional semen sample was collected 4 h after dose, and drug and metabolite concentrations were measured in this sample and the sample taken 1. Blood samples were collected before each dose and 0. It also did not affect ejaculate volume or viscosity. All measures were within normal ranges.

Sildenafil was well tolerated; no patient withdrew from the study due to adverse events attributed to sildenafil. Erectile dysfunction ED is a widespread condition that can have a negative impact on quality of life [ 1 ], affecting both older and younger men [ 2 ].

Until recently, no effective oral therapy existed. Available treatments were highly cumbersome or invasive, and many patients and their partners found them unacceptable solutions to the problem [ 3 ]. When administered before sexual activity, it produces reliable efficacy, good tolerability and rapid absorption that yields prompt onset of action; it has a plasma half-life that produces an appropriate duration of action while avoiding accumulation on repeated once-daily use [ 4 ].

In clinical trials, sildenafil has been shown to increase the duration and rigidity of penile erection in response to visual sexual stimuli in a hospital setting [ 4 ] and to greatly enhance the ability to achieve erections, leading to successful completion of intercourse in the home setting [ 5 ]. A large number of drugs can be transported into the seminal fluid, where they can have direct effects on sperm function, physiology, metabolism or genetic composition [ 6 ].

Several drugs have been shown to affect sperm motility in particular [ 7 ]; these include compounds with phosphodiesterase PDE -inhibitory activity that have the potential to increase motility [ 8 , 9 ]. One such drug, pentoxifylline, which is a cyclic adenosine monophosphate cAMP PDE inhibitor, has been shown to stimulate human sperm motility both in vitro and in vivo [ 10 ].

Sildenafil is a potent and selective inhibitor of the cyclic guanosine monophosphate cGMP -specific PDE type 5 enzyme [ 11 ] and thus enhances the activity of the nitric oxide—cGMP pathway that promotes penile erection. The drug is relatively lipophilic log D 7. It is likely that sildenafil will be used by men with ED as an aid to procreation, especially by younger patients who have ED secondary to spinal cord injury.

Because of this, a clinical study was conducted to investigate the effect of a single oral dose of sildenafil on a number of semen and sperm motility and morphology parameters. In addition, the concentrations of sildenafil and its major circulating metabolite UK, were measured in semen samples and compared with those obtained in plasma.

Written informed consent was obtained from each subject before study entry, and the study protocol was reviewed and approved by the Regional Committee for Medical Research Ethics, Oslo, Norway.

This double-blind, randomized, four-period, two-way crossover study compared mg doses of sildenafil with placebo, each administered as single oral doses for two periods separated by a washout period of at least 5—7 days. The repeat administration of both sildenafil and placebo was performed to correct for the inherent intrasubject variability in sperm motility and morphology measures.

Subjects who met the inclusion criteria underwent a prestudy screening in the 3 weeks before the start of the study that consisted of a physical examination, measurement of supine blood pressure and pulse rate, a lead electrocardiogram, laboratory safety tests blood and urine and a urine screen for drugs of abuse. A semen sample was also collected to exclude subjects who were azoospermic or had sperm motility that was not assessable. The subjects were asked not to ejaculate for a minimum of 3 days before each dose of study drug.

They were not permitted to consume products containing caffeine, methylxanthines or alcohol and were asked to refrain from unaccustomed exercise in the 48 h before each dose of study drug and while at the study centre.

The subjects also were required not to use prescription or over-the-counter drugs during the study and were not permitted to smoke at the study centre. The sponsor of the study provided sildenafil as mg tablets and matching placebo tablets, and the order of dosing was randomized.

The subjects were asked to have breakfast before attending the study centre on each of the four mornings of dosing. They did not receive study drug until a minimum of 2 h had elapsed after their last meal. All study medications were taken under supervision in the study centre, with ml of water, while standing or seated upright. Lunch and dinner were provided at 2 and 6 h after dose after blood sampling. Noncaffeinated drinks were permitted from 4 h after dose.

Semen samples were obtained at screening and 1. Only the screening and 1. For evaluation of sperm motility, aliquots of ejaculate were transferred to a Hamilton Thorn motility analyser after a liquefaction period of 30 min at room temperature as described in previous publications from our clinic [ 12 , 13 ]. The following parameters were determined:. Data regarding the reproducibility of repeated motility measurements five times on the same 10 ejaculates have been computed. The sperm samples used in this validation study were classified as borderline to normal.

An assessment of morphology and vitality was made after staining with eosin Y and Harris haemotoxylin. These analyses were carried out in a fertility clinic with access to patients per year.

The definitions of normality were derived from data obtained from these patients and described in a number of previous publications [ 14 — 17 ]. Blood samples 7 ml were collected at time 0 predose and after each dose of study drug at 0. Additional blood samples were taken 1 and 4 h after dose to assess plasma protein binding of sildenafil and UK, using equilibrium dialysis.

Semen samples were collected at 1. Samples were frozen until assay after pharmacodynamic analysis for the sample obtained 1. For both semen and plasma, assays for the drug and its metabolite were conducted using automated sequential trace enrichment of dialysates and previously validated high-pressure liquid chromatography with ultraviolet detection [ 18 ]. During the analysis for the estimation of total semen analyte concentrations, insufficient data were obtained to determine the overall imprecision of the assay.

Observed or volunteered adverse events were recorded throughout the study. A physical examination and supine blood pressure and pulse rate measurements were performed on each morning of dosing and after blood sampling 6 h after dose.

Laboratory safety tests were conducted before administration of the first dose of study drug, and urine screens for drugs of abuse and alcohol breath tests were performed on each morning of dosing. A follow-up visit was conducted 7—10 days after the last dose of study drug. Sperm motility parameters were subject to analysis of variance that ascribed variation in the data to subjects, periods, treatments, subject-by-period interaction and analysis time.

Sperm and ejaculate parameters were analysed in a similar manner but excluding terms involving analysis time. Ejaculate viscosity data were log-transformed to satisfy the distributional assumptions of the analysis of variance and presented as back-transformed geometric means. The relationships between total amounts and concentrations of sildenafil and UK, in the semen and the corresponding total and free drug plasma concentrations were analysed using linear regression methods.

Individual values were averaged over replicate treatments. All statistical analyses were performed using SAS version 6. Seventeen healthy male volunteers were enrolled in the study and eligible for safety assessment. One subject was withdrawn from the trial because of a serious adverse event after receiving placebo considered unrelated to treatment. The remaining 16 subjects completed the study. The subjects were between 19 and 34 years of age mean 24 years and weighed between 64 and 98 kg mean 80 kg.

All subjects were white. No significant medical conditions relevant to the study were noted before entry. The mean values for the sperm motility parameters were all within the normal ranges predefined by the study centre.

No significant difference was observed between sildenafil and placebo for any parameter Table 1 , indicating no effect on sperm function. However, there was some evidence of a small effect of time on progressive motility; the adjusted means, averaged over both treatment groups, were A time effect was also noted for lateral head displacement, which increased significantly from 2.

These differences were independent of treatment and of no clinical significance. Effect of sildenafil on sperm motility parameters. All data reported as adjusted means.

These variables were also all within the normal ranges predefined by the study centre. Effect of sildenafil on secondary semen analysis parameters. For ejaculate viscosity, data are presented as adjusted geometric means. Mean values for the pharmacokinetic parameters of sildenafil and UK, are presented in Table 3 , and the mean values for plasma and semen concentrations and total amount of drug in semen are summarized in Table 4.

Sildenafil was rapidly absorbed with a mean time to achieve the maximum observed plasma concentration of 1. The maximum observed plasma concentration of the metabolite also occurred at 1. Mean pharmacokinetic parameters for sildenafil and UK, Geometric means reported for AUC 6 and C max , arithmetic means reported for t max and plasma protein binding.

Total and free plasma concentrations, semen concentrations and total amount of drug in semen for sildenafil and UK, The concentrations of sildenafil in the semen at 1. The concentrations of UK, in the semen at 1. Concentrations of sildenafil in semen were greater than the free plasma concentrations of sildenafil, although the total amount of sildenafil ng and UK, Mean concentrations of sildenafil in semen were 3.

Mean UK, semen concentrations were 1. There was no evidence of a significant relationship between UK, semen concentrations and either total or free plasma UK, concentrations. Correlation of sildenafil concentrations in semen to total plasma concentrations a and free plasma concentrations b. No subject discontinued treatment due to adverse effects related to sildenafil. No clinically significant changes in laboratory values were reported.

A total of 17 healthy male volunteers were enrolled in this double-blind, placebo-controlled study to determine the pharmacokinetics of sildenafil and its pharmacodynamic effects on sperm function and ejaculate quality. Sixteen subjects completed the study. Although sildenafil is a member of a drug class PDE inhibitors previously shown to have some effects on sperm motility [ 8 , 9 ], a comparison of sildenafil vs placebo on a wide variety of measures in this study showed no effect on sperm motility, count, density, morphology or vitality and no alteration in ejaculate volume or viscosity.

The small but statistically significant increase in progressive motility and lateral head movement observed between the parameters measured 0. It has been hypothesized that the positive effect of pentoxifylline, a cAMP-specific PDE inhibitor, on sperm motility may be due to its pharmacological action on cAMP metabolism [ 10 ]. The semen and plasma concentrations of sildenafil suggest that the drug rapidly equilibrates between the blood and the accessory genital glands that produce the constituents of the ejaculate.
