Figure 1.
Sperm quality and FSH level before treatment. Sperm quality was divided into three categories: good quality if concentration of spermatozoa was ≥20×106/mL and motility ≥50%; poor quality if concentration of spermatozoa was <5×106/mL; intermediate quality for all other concentrations, except azoospermia. First vertical reference line: sperm concentration: 5×106/mL. Second vertical reference line: sperm concentration: 20×106/mL. Horizontal reference line: FSH: upper normal value; values above this line indicate elevated FSH and values below this line indicate non-elevated FSH. Two outliers are present; norm. FSH: normalized FSH.
