Degree of endosalpingeal deciliation (by S.E.M.) in hydrosalpinx is not prognostic for post-surgical fertility.

In 21 infertile patients, operated on for bilateral hydrosalpinges, multiple tubal biopsies, removed during surgery, were studied by light microscopy and scanning electron microscopy. Compared with control biopsies, taken from 12 fertile women, all cases but one showed flattening or loss of major and minor mucosal folds and epithelial deciliation. However postsurgical fertility rate, after 1-3 years follow-up, is not proportional to the percentage of ciliated cells.
