Abstract | Four hundred eighty-two patients undergoing single ET with GnRH-antagonist/recFSH protocol were analyzed. The incidence of premature luteinization (P above 1.5 ng/mL on the day of hCG administration) was 18.2%. Even modest rises of P in the follicular phase have detrimental effect on the implantation potential of a good-quality cleavage stage embryo. On the contrary, premature luteinization in the blastocyst subgroup had no effect on the pregnancy outcome. |
