Figure 5. Evolution of sperm quality parameters throughout the hormonal
treatments (hCG, hCG rec and PMSG): A) percentage of spermiating males; B)
sperm volume; C) sperm density; D) percentage of motile cells and E)
percentage of progressive motile cells. Data are expressed as mean±SEM and
different letters indicate significant differences between treatments at each
week of treatment.
