Abstract

Background The objective of the work was to investigate the cycle characteristics and outcomes of infertile women with nonclassic 21-hydroxylase deficiency (21-OHD) undergoing in vitro fertilization (IVF).

Methods Twenty-five infertile nonclassic 21-OHD patients were retrospectively observed. From cycle day 3, patients were given human menopausal gonadotropin (HMG) 150 IU/d or 225 IU/d daily. Dexamethasone was administered orally at 0.75 mg/d. Ovulation was co-triggered by human chorionic gonadotropin (hCG) and triptorelin. Binary logistic regression was performed to quantify the effect of IVF parameters on embryo transfer cycle outcomes. The receiver operating characteristic (ROC) curve was used to determine cutoff points of the selected confounders for predicting pregnant probabilities.

Results In controlled ovarian hyperstimulation (COH) cycles, there was a trend that the viable embryos group consisted of more polycystic ovary (PCO) patients. In embryo transfer (ET) cycles, differences were detected in the usage rate of dexamethasone and the minimum progesterone (P4) and total testosterone (TT) values between the non-pregnant group and the biochemical pregnant group. Binary logistic regression analysis confirmed that decreasing minimum P4 and body mass index (BMI) value was respectively correlated with increasing pregnancy probability. ROC analysis proved that the cutoff values for minimum P4 and BMI were 0.45 ng/ml and 23.36 kg/m2.

Conclusion In COH cycles, the ultrasonographic appearance of ovary helps to predict the number of viable embryos. In ET cycles, dexamethasone obviously improves the pregnancy rate. If the minimum P4 value before endometrial transformation cannot be kept below 0.45 ng/ml, we may consider cycle cancellation. Moreover, it is suggested that BMI of nonclassic 21-OHD women is regulated below 23.36 kg/m2.
