Endometrial surface changes by scanning electron microscope were studied in three
women who intentionally took high doses of levonorgestrel as an emergency postcoital …

Fertile women in the follicular phase possessed an uterine luminal surface with many
ciliated cells and with non-ciliated cells, which carried numerous, fairly long microvilli. A …

We studied the effect of intrauterine administration of levonorgestrel (LNG) on the
