Their answers were correlated to sperm quality. No association could be documented between sperm quality and smoking habits, coffee drinking, a moderate alcohol intake, exposure to heat (sauna, hot baths, type of underwear, sedentary activities), or physical activities in their leisure time. In contrast, the reported average ejaculation frequency was significantly positively correlated to the motility of the sperm (% progressive), and inversely related to the proportion of sperm with abnormal morphology and semen volume.

Serum PEP concentration in patients who successfully conceived was 102.5 +/- 62.6% units/mL, while PEP concentrations in patients who failed to conceive were 57.9 +/- 34.4% (P = .003).

The increment patterns of serum estradiol during the follicular phase and progesterone levels in both groups were identical.
