CHAPTER 2
With regard to the sperm motility classes, hCG rec treatment induced good
quality samples (IV) in every week of treatment (except in the 5 th week),
while hCG and PMSG treatments showed some weeks without good sperm
samples (weeks 6 and 3, respectively) throughout the treatment (Fig. 7).
hCG rec and PMSG treatments produced better volume profiles (with class IV
sperm volumes around 70% and 60%, respectively) than hCG treatment,
which resulted in values of less than 30% for the same motility class (Fig. 6).
