Abstract:
Objective:To investigate whether there are differences in clinical pregnancy and perinatal outcomes among different protocols for artificial insemination by donor (AID) in female patients aged ≤35 years.Methods:This retrospective cohort study analyzed clinical data of patients who underwent AID at the Reproductive Medicine Center of the Third Affiliated Hospital of Zhengzhou University from January 1, 2016 to January 31, 2021. Based on ovulation induction therapy, patients were divided into 4 groups: natural cycle (NC) group, letrozole (LE)/clomiphene (CC) group, gonadotropin (Gn) group and LE/CC combined with Gn (LE/CC+Gn) group. The clinical outcomes, incidence of complications, and offspring health were compared among these groups, and logistic regression analysis was employed to investigate the effects of different protocols on the clinical and perinatal outcomes of AID cycles.Results:In NC group, LE/CC group, Gn group and LE/CC+Gn group, the cycle cancellation rate [0.5% (11/2 147), 1.1% (12/1 045), 1.6% (9/549), 3.2% (9/315), P<0.001], the clinical pregnancy rate [31.5% (673/2 136), 35.8% (370/1 033), 42.8% (231/540), 38.2% (117/306), P<0.001], the multiple pregnancy rate [0.7% (5/673), 3.2% (12/370), 3.5% (8/231), 6.8% (8/117), P<0.001], the abortion rate [12.8% (86/673), 9.2% (34/370), 5.2% (12/231), 8.5% (10/117), P=0.008] and the live birth rate [27.2% (581/2 136), 31.4% (324/1 033), 40.0% (216/540), 34.3% (105/306), P<0.001] were statistically significant, while the differences among the four groups in the ectopic pregnancy rate, the preterm birth rate, and the overdue birth rate were not statistically significant (all P>0.05). After adjusting for confounding factors, the differences were not statistically significant in all indicators compared with the NC group (all P>0.05), except for the miscarriage rate in the LE/CC+Gn group, which was significantly higher than that in the NC group (a OR=2.141, 95% CI: 1.12-4.09; P=0.021). For patients who have been using the same treatment protocol, the cumulative pregnancy rate and the cumulative live birth rate in the NC group and the LE/CC group increased with the increase of assisted reproductive cycles, and the difference was statistically significant (all P<0.001). Regardless of whether confounding factors were adjusted, there were no statistically significant differences in neonatal mortality rate, low birth weight rate, normal birth weight rate, macrosomia rate, and male-to-female ratio among the groups (all P>0.05). Conclusion:In AID cycles with female patients aged ≤35 years, stimulated cycles had similar pregnancy outcomes to natural cycles and did not increase the risk of adverse neonatal outcomes or multiple pregnancies. Choosing the LE/CC stimulation protocol can improve the cumulative pregnancy rate of patients with abnormal ovarian follicle development or ovulation function.
