OBJECTIVE: To characterize the semen quality of Filipino male partners of couples with infertility and determine the effects of age.
DESIGN: Retrospective study.
SETTING: Andrology laboratory at a tertiary care hospital.
PATIENTS: 2,701 males.
MAIN OUTCOME MEASURES: Routine semen analysis.
RESULTS: Average age of the study population was older and azoospermia occurence was lower than in previous studies. A large proportion had parameters below the WHO reference values. A decreasing trend for all semen parameters across increasing age was observed. For males -51 years old almost all parameters were below WHO values. Subject with abnormal parameters were significantly increasing across age. Occurence of severe oligozoospermia in older males was significantly increased compared to younger males.
CONCLUSION: The study characterized the current status of semen quality in this subpopulation, a very large proportion of which had values below WHO reference. The data illutrate that as men age, semen quality declines.
