THE PRESENCE OF HYDROSALPINX MAY NOT ADVERSELY AFFECT THE IMPLANTATION AND PREGNANCY RATES IN IN-VITRO FERTILIZATION TREATMENT

Purpose: To evaluate the effects of hydrosalpinx on the outcome of in vitro fertilization (IVF) treatment, a retrospective study was underta ken at a tertiary referral center for infertility. Methods: Results of the first NF treatment cycles in 144 patients from I January 1993 to 31 December 1995, who had tubal infertility only and were less than 38 years old, were reviewed. The duration/dosage of hMG used, serum estr adiol level on the day of hCG, number of oocytes aspirated and fertili zed, number of embryos replaced, implantation rate, clinical pregnancy rate, and pregnancy outcome were compared in patients with and withou t hydrosalpinx Results: The mean implantation rate and clinical pregna ncy rate were similar in patients with or without hydrosalpinx. Both g roups had similar ovarian responses and fertilization rates. There was no increase in clinical abortion in the hydrosalpinx group but ectopi c pregnancies were more common in patients with hydrosalpinx. Conclusi ons: The presence of hydrosalpinx did not adversely affect the implant ation and pregnancy rates in in vitro fertilization treatment when the results of the first cycle were compared However; it can lead to a hi gher incidence of ectopic pregnancies.
