Investigation of different etiologies of infertility in patients referred to Birjand infertility center, 2021-2022

Background and Aims:A significant part of infertility has been related to environmental conditions as well as acquired risk factors.Different environmental conditions emphasize the necessity of studying different etiologies of infertility in each region.The present study aimed to determine the etiologies of infertility in infertile couples. Materials and Methods:In this cross-sectional study, 583 infertile men and women referred to the infertility clinic from 2021 to 2022 were examined.In addition, sampling was performed using the census method.Information about patients was obtained from medical tests and laboratory findings.It is noteworthy that descriptive statistics, such as frequency and mean, were used to analyze the data.Results: According to the results, oligospermia was the most common cause of male infertility (44.72%), and ovulation disorder was the most prevalent reason for female infertility (66.17%).In general, ovulation disorder and sperm motility were the most common causes of infertility (36.73%).There was no significant relationship between women's underlying diseases and the causes of infertility (P>0.05). Conclusion:The etiology pattern of infertility is closely similar to that of many other regions reported by the World Health Organization (WHO).Despite this, the rate of ovarian disorders is higher than that in many other studies, which needs further studies.
