Prerequisite work-up of the couple before in-vitro fertilization.

Prerequisite examinations, including immune status for rubella and hepatitis B antigens, cultures for Chlamydia trachomatis and mycoplasmas, Pap smear and hystersalpingogram were performed in 227 couples before their enrollment into an in-vitro fertilization (IVF) programme. The examinations were completed in 187 couples. Immune status for rubella had already been documented in 45% of the women: of the remainder, 11 patients were not immune (6%). A screening test for hepatitis B antigens had already been documented in only 10% of the patients; eight of the remaining women (5%) were carriers of hepatitis B antigen. C. trachomatis and Mycoplasma hominis were each isolated from 14% of the patients and Ureaplasma urealiticum from 16%. Pap smears had been previously performed in only 35% of the enrolled women. Six (5%) of the 122 newly referred cases had cervical intra-epithelial dysplasia. In 21 (11%) cases some pathology in the uterine cavity was demonstrated. One patient conceived after diagnostic hysteroscopy; another two patients conceived following lysis of adhesions and before IVF treatment. The results of this study show the importance of the preparatory examinations before the IVF and embryo transfer procedure, and raise the medical and medico-legal aspects of this prerequisite work-up.
