The diagnosis of infertility not only involves biological but the psychosocial links have also been established. Individual difference variables, such as personality and temperament have been found playing prominent role in modifying the psychological and biological aspects of infertility. This systematic review aimed to examine evidence-based research on the role of personality traits in determining vulnerability to stress in infertility, understand the gender-based differences, and deliver suggestions for future researches.
The search for studies relating to the variables was accomplished using various electronic databases. The search was kept limited to a time span of about 20 years, that is, from January 2000 to April 2020. Additional researches were collected from library source and others were retrieved by contacting experts. Studies were selected on the basis of a predetermined inclusion and exclusion criteria, and quality of the studies was also taken into account.
The search of studies through above methods was fruitful in identifying 23 studies including six longitudinal and prospective studies, and 17 cross-sectional studies covering both individual- and model-based personality attributes related findings. The overall quality ratings of the studies ranged from fair to good.
The review revealed that personality factors such as neuroticism, harm avoidance, and psychoticism are the potential risk factors, whereas optimism has a protective impact in the context of fertility disorders. The long-term impact of personality on infertility needs further exploration. Trait modification interventions during the treatment of infertility were also suggested in the light of previous findings.
不孕不育的诊断不仅涉及生物学因素，而且还建立了心理社会联系。个体差异变量，如性格和气质，已被发现对不孕不育的心理和生物学方面具有显著的调节作用。本系统评价旨在考察人格特质在确定不孕不育易感性方面的循证研究，了解基于性别的差异，并为未来的研究提供建议。
使用各种电子数据库来搜索与这些变量相关的研究。搜索范围限于大约 20 年的时间跨度，即从 2000 年 1 月到 2020 年 4 月。从图书馆资源和通过联系专家获取其他资源来收集额外的研究。研究是根据预先确定的纳入和排除标准选择的，同时也考虑了研究的质量。
通过上述方法进行的研究搜索在识别 23 项研究方面取得了成果，其中包括 6 项纵向和前瞻性研究，以及 17 项涉及个体和基于模型的人格属性相关发现的横断面研究。研究的总体质量评分从一般到良好不等。
该综述表明，神经质、回避和精神病等人格因素是潜在的风险因素，而乐观在生育障碍的情况下具有保护作用。人格对不孕不育的长期影响需要进一步探索。根据以往的发现，还建议在治疗不孕不育时进行特质修正干预。
