[The analysis of preliminary spermatological parameters in potential donors of semen].
OBJECTIVE
To contribute to the contemporary discussion on the male factor infertility through the evaluation of the basic spermatological parameters in men recruiting for semen donation.


METHODS
A retrospective demographic study.


METHODS
Dept. of Obstetrics and Gynaecology, Dept. of Biology, Faculty of Medicine, Palacký University, Olomouc.


METHODS
A total of 108 men aged 18 to 35 years came to the preliminary examination for the potential semen donors between January 2000 and April 2004. Spermatological analysis of the fresh ejaculates obtained by masturbation was performed according to WHO guidelines. The following parameters were evaluated: the volume of ejaculate, sperm concentration and total percent motility.


RESULTS
Normospermia was found in only 46 men (42.6%). Three males (2.8%) were azoospermic. The most frequent problem was asthenospermia, which was documented in 49 (46.6%) men.


CONCLUSIONS
The analysis of the obtained data may suggest a marked semen quality decline in the Czech male population. In our opinion, further multicentric epidemiological studies concerning fertility potential in Czech male population seem highly needed.
