Objective.
To investigate the feasibility and clinical outcome of the all-blastocyst-culture and single blastocyst transfer strategy in women aged ≥35 years.
Methods.
A retrospective analysis of patients aged ≥35 years undergoing IVF/ICSI was performed from January 2017 to April 2019 in the reproductive center of the Second Affiliated Hospital of Wenzhou Medical University.
A total of 155 cases treated with ovarian hyperstimulation by prolonged protocol and implemented single (84 cases) or double (71 cases) blastocyst transfer were collected.
Then, patients were further divided into <38 yr.
group and ≥38 yr.
group, and the laboratory and clinical outcomes were compared between the groups.
Results.
The double-blastocyst-transfer (DBT) group showed higher clinical pregnancy rate and multiple pregnancy rate and lower neonatal birth weight than those in the single-blastocyst-transfer (SBT) group (P<0.05).
However, there were no statistically significant differences between the groups in the embryo implantation rate, biochemical pregnancy rate, miscarriage rate, preterm delivery rate, and term birth rate.
For patients<38 yr., SBT significantly reduced the multiple pregnancy rate and increased the neonate birth weight without significant reduction in the clinical pregnancy rate.
While in the ≥38 yr.
group, there are no differences in pregnancy outcomes between SBT and DBT.
Logistic regression analysis showed that the number of MII oocytes was positively correlated with the live birth rate (OR=1.18) and negatively correlated with the miscarriage rate (OR=0.844), suggesting that elderly patients with relatively normal ovarian reserve would obtain better prospect in pregnancy.
The number of fetal heart beat in pregnancy was negatively correlated with the live birth rate (OR=0.322) and positively correlated with the preterm birth rate (OR=7.16).
Conclusion.
The strategy of all-blastocyst-culture and single blastocyst transfer is feasible, safe, and effective for elderly patients with normal ovarian reserve, which would reduce the multiple pregnancy rate.
