The evolution of experimentally induced hydrosalpinges in rabbits.
Damage to fallopian tubes caused by hydrosalpinges is a major reason for persisting infertility. We describe the mucosal changes that occur following induction of experimentally induced hydrosalpinges in 25 rabbits. Ampullary biopsies obtained at varying intervals were examined with light microscopy and scanning and transmission electron microscopy. Mucosal folds showed progressive atrophy. The epithelium was flattened. The population of ciliated cells decreased and, finally, deciliation became generalized. The morphology of nonciliated cells changed from an initial high content of granules of secretion to a final stage of vacuolated cytoplasm. Cell desquamation was common.
