Etiology and risk factors associated with infertility

Abstract

Objectives: Infertility is one of the important complications in gynecology and the aim of the present study was to investigate the etiology and risk factors associated with infertility in the southern region of Iran. Materials and Methods: This cross-sectional study was conducted in infertility centers of Hormozgan University of Medical Science (HUMS). Totally, 250 infertile couples were included. The variables including socio-demographic characteristics, smoking, body mass index (BMI), and infertility status (e.g., type of fertility, duration, etc.) were assessed by a self-administered and validated questionnaire. Data analysis was carried out using SPSS version 22.0. Results: The most common causes of male and female infertility were varicocele (49.4%) and ovulation disorders (57.5%), respectively. There was a significant association between female factor infertility and level of education, age of women, women’s age at marriage, number of abortions, alcohol consumption, presence of an underlying disease, and BMI (P < 0.005). There was also a significant relationship between male factor infertility and men’s job, addiction, smoking, and presence of an underlying disease (P < 0.005). Conclusions: Considering various risk factors for infertility, an important step forward can be taken towards reducing the incidence of these risk factors by providing different education classes during pre-marriage, pre-partum, pregnancy and postpartum periods so as to inform couples of controllable risk factors.
