Cystic fibrosis transmembrane conductance regulator (CFTR) is relevant to sperm quality, sperm capacitation and male fertility. However, it is still unknown whether CFTR can be a potential parameter for fecundity prediction in healthy couples. In this study, 135 healthy couples were divided into groups according to their fertility. We demonstrated that the sperm CFTR expression level of healthy males...
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...
The aim of this study was to investigate the effect and significance of l‐arginine and ageing on nitric oxide (NO)‐cyclic guanosine monophosphate (cGMP) pathway and ET‐1 in penile tissue of rats. The different months old rats were divided into control group and experiment group randomly, the content of NO, cGMP, the changes of activity of Nitrous Oxide Systems (NOS) and the content of endothelin‐1(ET‐1)...
