ABSTRACT
Background:
Semen analysis is one of the parameters used to predict male fertility. Semen can be altered by environmental pollutants; therefore it could be used as a biological marker of exposure in contaminated areas.Aim:
To analyze the spermogram values in a sample of healthy young males, residing in Arica, Chile. Material andmethods:
One hundred and two healthy university students volunteers aged 18 to 30 years answered a questionnaire about fertility, habits and andrologic diseases and provided a semen sample. Within three hours after ejaculation, semen volume, pH, sperm concentration, motility and morphology were analyzed.Results:
Six percent of volunteers had offspring, 1 percent declared to be infertile, 32 percent smoked and 78 percent con-sumed alcohol. Semen pH was 7.6 ± 0.5, volume, 2.9 ± 1.6 ml, sperm concentration, 62.8 ± 62.3 x 10(6)/ml, normal morphology, 15.0 ± 7.9 percent, overall motility, 42.2 ± 23.2 percent and grade A motility, 19.2 ± 18.6 percent. The percentage of subjects that had normal semen values was 82 percent for total sperm count, 76 percent for sperm concentration, 72 percent for volume, 64 percent for vitality, 63 percent for pH, 57 percent for morphology, 38 percent for overall motility and 26 percent for grade A motility.Conclusions:
This sample of healthy young males had a normal sperm count in comparison with international reports. However it is necessary to characterize the spermogram in uncontaminated areas of Chile to ensure that our results are within the expected values for the country.
