High initial values of beta-subunits of human chorionic gonadotropin in ovum donation pregnancies indicate better implantation.
Fifty-five patients were treated by ovum donation, and a control group of 165 patients underwent IVF. The number of pregnancies obtained were 28 and 25, respectively. The initial beta-hCG values, as well as the PRs and implantation rates, in the ovum donation series were significantly higher than those of the IVF series. The clinical significance and potential application of these observations are discussed.
