Abstract
In this study, we aimed to investigate whether progesterone-induced acrosome reaction (AR) rate could be an indicator for fertilisation rate in vitro. Twenty-six couples with unexplained infertility and undergoing in vitro fertilisation (IVF) treatment were involved. On the oocytes retrieval day after routine IVF, residual sperm samples were collected to receive progesterone induction (progesterone group) or not (control group). AR rate was calculated and fertilisation rate was recorded. The correlation between progesterone-induced AR and fertilisation rate and between sperm normal morphology and 3PN (tripronuclear) were analysed using the Spearman correlation analysis. The AR rate of progesterone group was statistically higher than that of the control group (15.6±5.88% versus 9.66±5.771%, P<0.05), but not significantly correlated with fertilisation rate (r=-0.053, P>0.01) or rate of high-quality embryo development (r=-0.055, P>0.01). Normal sperm morphology also showed no significant correlation with the amount of 3PN zygotes (r=0.029, P>0.01), rate of 3PN zygotes production (r=0.20, P>0.01), rate of 3PN embryo development (r=-0.406, P>0.01), fertilisation rate (r=-0.148, P>0.01) or progesterone-induced AR rate (r=0.214, P>0.01). Progesterone can induce AR in vitro significantly; however, the progesterone-induced AR may not be used to indicate fertilisation rate.
