In vivo assessment of the human sperm acrosome reaction and the expression of glycodelin-A in human endometrium after levonorgestrel-emergency contraceptive pill administration

摘要: sies. RESULTS: Twenty-four and forty-eight hours after treatment, there were 14.5+ 3.9 3 10 6 17.3+ 6.8 sperm recovered from the uterus, respectively. There no differences between AR rate endometrial glycodelin-A staining intensity in an LNG or placebo treated cycles. The uterine flushing medium represented 1.38% of values observed serum 24 h intake. CONCLUSIONS: administration EC, neither proportion sperm, nor level was influenced by 1.5 mg LNG. did not impair cervical mucus either because viable spermatozoa found genital tract 36–60 coitus 24–48 mechanism action as EC remains unknown.
