Psychological Symptoms, Stress Trajectories, and Pregnancy Outcomes in Women Undergoing In Vitro Fertilization–Embryo Transfer: A Prospective Longitudinal Study
This prospective longitudinal study of 183 women undergoing IVF-ET reveals that psychological distress follows dynamic trajectories influenced by coping styles and social support, with higher baseline distress independently predicting reduced clinical pregnancy odds, thereby supporting the integration of early psychosocial monitoring into fertility care.

For millions of couples around the world, the path to starting a family is not a straight line but a winding road filled with medical procedures, financial strain, and deep emotional uncertainty. When natural conception does not happen, many turn to in vitro fertilization, a medical process where eggs are collected, fertilized in a laboratory, and then placed back into the uterus. While the biology of this process is well understood, the human experience of undergoing it is complex. It is a journey that demands immense physical endurance and psychological resilience. For decades, doctors and researchers have known that the stress of infertility treatment can be overwhelming, often leading to anxiety and depression. However, most previous studies have only taken a single snapshot of a woman's mental state at one moment in time, leaving a gap in our understanding of how these feelings actually shift and change as the treatment progresses from the first appointment to the final moment of waiting for a pregnancy.
A team of researchers at Peking University Shenzhen Hospital decided to look at this journey differently. Instead of taking a single snapshot, they followed 183 women through the entire cycle of treatment, checking in with them at three critical moments: when they first began the process, when the eggs were collected, and when the embryos were transferred. Their goal was to map the emotional landscape of these women, seeing not just how stressed they were, but how their stress moved and changed over time. They wanted to understand what personal factors, such as how a woman copes with difficulty or how supportive her family and partner are, might act as a shield against distress or, conversely, make the burden heavier. Crucially, they also asked whether the emotional state a woman entered the treatment with could predict the final outcome: whether she would successfully become pregnant.
The study revealed that the emotional experience of in vitro fertilization is not a flat line of constant suffering, nor is it a simple rise and fall. Instead, the path each woman walked was unique, shaped heavily by her personal resources and how she handled the pressure. The researchers found that the way a woman dealt with stress mattered more than the stress itself. Women who tended to submit to circumstances or avoid thinking about the problem found their distress growing heavier as the treatment went on. In contrast, those who had strong, supportive relationships with their spouses and families saw their stress levels drop significantly as they moved through the different stages of treatment. It appeared that a supportive environment did not just offer a momentary comfort; it acted as a buffer that helped women recover and stabilize as the medical procedures continued.
Perhaps the most significant finding concerned the link between a woman's mental state at the very beginning of treatment and her chances of success. The data showed that women who started the process with higher levels of psychological distress were less likely to achieve a clinical pregnancy. Specifically, for every small increase in the initial distress score, the odds of becoming pregnant decreased slightly. This suggests that the emotional burden a woman carries before treatment begins is not just a side effect of infertility but a factor that may influence the biological outcome. The study also noted that employment status played a role, with unemployed women having lower odds of pregnancy compared to those who were working, and that women who were not only children had higher odds of success than those who were. These factors, combined with the psychological data, paint a picture where social and emotional contexts are deeply intertwined with biological results.
The researchers concluded that the emotional journey of in vitro fertilization is dynamic and heavily influenced by how a person interacts with their world. The study argues that medical care for infertility should not stop at the physical procedures. Instead, it suggests that healthcare providers, particularly nurses who spend the most time with patients, should monitor these emotional shifts from the very start. By identifying women who are struggling with maladaptive coping styles or who lack social support early on, clinics could offer targeted help to ease the psychological burden. This approach does not promise a cure for infertility, but it offers a clearer understanding of how to support the people undergoing it, potentially improving their well-being and, as the data suggests, their chances of a successful pregnancy.
