Abstract:
A method has been developed of injecting gonadotrophins vaginally every 3-4 days, to reduce both the dose and frequency of injections. A couple with primary infertility for 5 years with a previous failed IVF cycle was recruited. A total dose of 1200 IU gonadotrophins was administered in three injections. Ten mature oocytes were recovered and six fertilized two-pronuclear stage zygotes resulted. The patient conceived after replacement of three good quality embryos.
