ABSTRACT
Background: Approximately 14% of couples of reproductive age have a fertility problem, defined as the inability to achieve pregnancy after a year of frequent intercourse without contraceptive protection.Objective: To determine the prevalence of retrograde ejaculation in infertile patients with hypospermia and to establish the effects of the treatment.
Material and method: Comparative study. A semen analysis of 207 patients with male infertility with hypospermia was performed. The patients with retrograde ejaculation were identified and its prevalence was calculated. Semen parameters were compared before and after treatment by means of a paired-t test. Hormonal levels also were compared between groups with and without retrograde ejaculation bymeans of a Mann-Whitney U test.
Results: Prevalence of retrograde ejaculation was 3.2% out of 2,587 infertile patients. Within the group of 207 patients with hypospermia, 84 had retrograde ejaculation. After the treatment the seminal volume increased (from 1.2 to 1.5 milliliters) and the number of mobile cells increased (from 47.2 to 62.5 millions). The number of sperm in urine decreased (from 22 to 10 per high-power field). The patients with retrograde ejaculation had lower levels of follicle-stimulating hormone, luteinizing hormone and testosterone than those without retrograde ejaculation.
Conclusions: Retrograde ejaculation and hypospermia are both considered infrequent but important alterations in infertility. Prevalence of retrograde ejaculation in patients with hypospermia is 40.5%. Treatment increased seminal volume and the number of mobile cells in the ejaculated semen. It is necessary to perform future studies in order to determine the impact of severity of retrograde ejaculation on infertility.
