RESUMO
OBJECTIVE: To compare the changes that occurs in the spermatic parameters when a second ejaculate is obtained in the first 60 minutes in patients with a different seminal quality. MATERIAL AND METHOD: Infertile patient from andrology service were asked to provide a second sample within 1 hours of the first. All the patients had poor semen characteristics in volumen, density, motility or total motile cells. RESULTS: The patients were divided in subgroup; hipospermia (n = 75), oligospermic (n = 46), asthenospermic (n = 111) and teratospermic (n = 157). A benefic effect from a second ejaculate sample was observed in patients with asthenosperia, oligospermic and a total motile sperm count less than 10 million (p < 0.05). CONCLUSIONS: The second ejaculate must be considered as an alternative in some infertile patients that are looking for an spontaneous pregnancy or in patients that will require an assisted reproductive techniques and have poor seminal parameters.
