This prospectively designed study was aimed at comparing the results of two
different treatment protocols in 29 infertile couples with proven male
immunological infertility, i.e. a positive (>50%) mixed antiglobulin
reaction (MAR) test (IgG and/or IgA). In the first protocol (group I, n =
14) couples were treated with ovarian stimulation/ intrauterine
insemination (IUI), followed by in-vitro fertilization (IVF) if no
pregnancy occurred after three IUI cycles. In the second protocol (group
II, n = 15), patients were treated with IVF as a first choice procedure.
The decision to follow protocol 1 or 2 was made by the couples after
information about financial costs and expected success rates (according to
the literature) for both treatment options. In group I, nine patients
(64.3%) conceived after a maximum of three IUI cycles whereas seven
patients (46.6%) of group II became pregnant during the first IVF cycle.
The take-home baby rate per started IUI or IVF cycle was 27.3% (9/33) and
44.4% (16/36) respectively with a take-home baby rate of 64.3% after three
IUI cycles and 93.3% after three IVF attempts. To conclude, both IUI and
IVF yielded unexpectedly high pregnancy rates in this selected group of
patients with long-standing infertility due to sperm surface (predominantly
IgG) antibodies. Since cost benefit analysis comparing superovulation IUI
with IVF may favour a course of four IUI cycles, we advocate superovulation
IUI as the first line therapy in male immunological infertility.
