Percentages of viable sperm with an intact acrosome membrane (PNA⁻FITC-/PI⁻ population) (a) and viable sperm with low intracellular calcium levels (Fluo3-/PI- population) (b) during in vitro capacitation and acrosomal exocytosis induced by progesterone (300 min). The black arrows indicate the addition of progesterone at a final concentration of 10 μg/mL (240 min). Data are represented as means ± SD. Different letters indicate significant differences (p < 0.05) between sperm samples containing high and low relative levels of PARK7.
