oxalates and Infertility--Male

To determine the level of oxalate in seminal plasma and to correlate it with andrologic variables.. Laboratory examination.. University-based department of andrology and department of clinical chemistry.. One hundred male outpatients with infertility.. Isolated seminal plasma was stored for 120 days at -20 degrees C.. Levels of oxalic acid in seminal plasma.. Oxalate levels in seminal plasma depend on the degradation of ascorbic acid to oxalic acid during storage. There was a linear nonenzymatic increase of oxalate with storage time. After 120 days of storage, the values were 133 +/- 50 micromol/L (n = 100). Oxalic acid correlated significantly with the number of sperm head anomalies, the pH value, and the age of the donors and correlated negatively with the volume of ejaculate.. Oxalic acid in seminal plasma may influence male fertility.
