HYDROSALPINX REDUCES IN-VITRO FERTILIZATION-EMBRYO TRANSFER PREGNANCYRATES

A retrospective study was designed to examine whether the presence of a hydrosalpinx influenced pregnancy outcome following in-vitro fertili zation (IVF) treatment in stimulated cycles. A total of 254 women with tubal lesions were included. Patients with one or two hydrosalpinges were compared with patients having other tubal lesions and pregnancy o utcome was analysed. Both pregnancy and delivery rates were significan tly higher in the patient group without a hydrosalpinx. The results af ter frozen embryo transfer showed the same tendency. These findings st rongly indicate that a permanent hydrosalpinx has a negative influence on implantation, as well as on pregnancy, and suggest that a more act ive approach against large hydrosalpinges should be undertaken before IVF treatment, in order to improve the pregnancy rates.
