BackgroundThe aim of this study was to quantitatively analyze the psychosocial characteristics of in vitro fertilization-embryo transfer (IVF-ET) couples and normal couples, and to identify the influencing factors of psychological characteristics and pregnancy outcomes.Material/MethodsThere were 260 infertile couples undergoing IVF-ET and 277 healthy couples of childbearing age in Shengjing Hospital of China Medical University recruited into 2 groups. Psychosocial characteristics were compared to analyze the influencing factors of pregnancy outcomes after IVF-ET. In-depth interviews (n=11) and infertility-related forum posts (n=12) were adopted to obtain the data related to the psychological experience and adjustment. Nvivo 11 software was utilized to collect and analyze the data.ResultsThe levels of anxiety and depression in the IVF-ET group were significantly higher (both P<0.01), the total scores of marital quality scale and social support scale were significantly lower (both P<0.05), immature defense mechanism score was significantly higher (P<0.05), and mature defense mechanism score (P<0.05) was significantly lower than those in the control group. Bod mass index (BMI), family’s rural residence, marital quality, and immature and mature defense mechanisms were influencing factors of depression in IVF-ET female patients (all P<0.05). Marital quality, mature and immature defense mechanisms, concealment factors, and Harm Avoidance (HA) score were influencing factors of depression in IVF-ET males (all P<0.05). The age of the female patient was an independent influencing factor of IVF-ET pregnancy success rate (P<0.01).ConclusionsThe mental health levels of IVF-ET patients were worse than those of fertile couples. The younger the female infertile patient, the higher pregnancy rate of IVF-ET.
