Does melatonin affect sperm?

In 2 men, during the melatonin treatment period, sperm concentration decreased to 3 x 10(6)/mL and 12 x 10(6)/mL, and motility declined to 32% and 30%. These coincided with a decline in seminal plasma and serum E(2) levels and with an increase in testosterone:E(2) ratios.
