ObjectiveTo investigate the effectiveness and limitations of multifetal pregnancy reduction (MFPR) on the improvement of pregnancy outcomes of triplet or twin pregnancies conceived by in vitro fertilization (IVF) or intracytoplasmic sperm injection (ICSI).MethodsWe performed a cohort study of women undergoing IVF or ICSI from 2002–2016 in reproductive center, women’s hospital, Zhejiang University School of Medicine. The cohort included 502 women who underwent MFPR and 9641 non-reduced women. Pregnancy outcomes were gestational age (GA) at delivery, pregnancy loss, preterm delivery, low birth weight (LBW), very low birth weight (VLBW), and small for gestational age (SGA). Multiple linear regression and logistic regression models were used to compare pregnancy outcomes between groups.ResultsTriplets reduced to singletons had a longer median GA (39.07 vs 37.00, PConclusionsThis study suggests that the pregnancy loss rate is similar between reduction and non-reduction groups. MFPR improves pregnancy outcomes, including the risk of preterm delivery, LBW, and SGA, but still could not completely reverse the adverse pregnancy outcomes of multiple pregnancies.

Objective This study investigated the medical coping styles of female patients treated with in vitro fertilization and embryonic transfer (IVF-ET), and analyzed the effects of alexithymia and social support on their choice of coping style. Methods A survey was conducted with 285 female patients undergoing IVF-ET in a reproductive medical center of a third-grade class-A hospital in China using the Medical Coping Modes Questionnaire, the Social Support Rating Scale, and the Toronto Alexithymia scale. Results Patients who underwent IVF-ET treatment had a higher score for avoidance as a coping mode than did normal controls. Utilization of social support predicted the use of confrontation as a coping style. Difficulty identifying feelings, objective support, and utilization of social support were factors in the choice of avoidance as a coping style, and length of infertility treatment, difficulty identifying feelings, and subjective support predicted patients' use of the acceptance-resignation as a coping style. Conclusion Patients who undergo IVF-ET generally select the coping style of avoidance, which is not conducive to treatment. Targeted intervention strategies should be developed based on the factors influencing patients' choice of coping style(s) to guide them in choosing positive coping methods, improve compliance, and achieve successful pregnancy outcomes.
