The purpose of this study was to compare the clinical efficacy of
gonadotrophins administered s.c. or i.m., in a prospective randomized study
of women undergoing in-vitro fertilization (IVF) treatment at a tertiary
referral centre. In all, 71 patients undergoing a total of 162 IVF
treatment cycles were randomized to receive either s.c. (n = 41) or i.m. (n
= 30) administration of gonadotrophins. Up to three cycles of IVF were
assessed for each patient. The main outcome measures were the number of
oocytes retrieved, the total amount of gonadotrophins used, the number of
follicles recruited and the cumulative pregnancy and live birth rates. The
mean number of oocytes retrieved was 10.5 for each group. The number of
days of stimulation was significantly shorter for the s.c. group (11.7 +/-
1.9 days, mean +/- SD) than the i.m. group (12.6 +/- 2.3 days). The
cumulative conception and live birth rates after three cycles of treatment
were similar between the two groups. Our results suggest that the clinical
efficacy of s.c. and i.m. administration of gonadotrophins is comparable.
Both routes are well tolerated by patients.
