Methods Eighty-three women defined as secondary infertility were enrolled into this study. Based on their outcomes of previous pregnancy, these women were divided into two groups： group HC （having at least one child, n=45）, group NC （no child but one to three abortions, n=35）. The serum was screened by the indirect immunobead test for ASA type IgG and IgA according to the WHO laboratory manual. Results Of the 83 patients assessed for ASA-IgG, 14 had immunobead binding rate ranged from 15% to 43%, and the sub-positive rate was 16.9%. Five cases showed ASA-IgA sub-positive, and had binding rate between 10% and 20%. No case had the clinical positive level according to the WHO criteria. No differences were found on ASA-IgG and ASA-IgA between HC and NC groups （P〉0.05）. Conclusion The circulating ASA may be a possible cause to decrease fertility in women with secondary infertility.展开更多

Objectives: The study aimed to determine types of infertility and their contributing factors among the respondent infertile women. Methods: This prospective cross-sectional study was conducted among infertile women visiting Sir Salimullah Medical College and Hospital, Dhaka. From January to December 2020, 111 infertile women were included and evaluated for infertility types and their contributing factors. Data were collected by face-to-face interviewing, and data were analyzed statistically. Results: Primary infertility was found among 90 (81%) and secondary infertility among 21 (18.9%). Among the direct risk factors of female infertility, ovulation failure was the majority of the cases, 74 (35.1%), and its mainly observed in primarily infertile women 58 (33.9%). These observations were statistically significant. Conclusions: Infertility should be treated as a public health problem, government and non-government organizations should develop a basic policy to create effective fertility centers.展开更多

The increased incidence of anticardiolipin (ACL) antibodies in infertile women supports the contention that these autoantibodies contribute to the infertility. Objectives: To investigate whether there is an association between the presence of serum ACL antibodies and infertility in both men and women in Diyala province. Subjects and methods: The present study was conducted in Baquba city for the period from October 2013 to November 2014. Subjects included in this study were chosen from those attending Baquba Teaching Hospital, Al-Batool Teaching Hospital for Maternity and Children and some Primary Health Care Centers in Baquba. The subjects were categorized as follows: 30 apparently healthy males with age ranged between (18 - 45) years;30 apparently healthy women (age range: 18 - 47 years) had at least two live births without any miscarriages;25 women (age range: 18 - 43 years) had reproductive failure for at least one year of marriage;30 women (age range: 24 - 44 years) with at least one live birth had no pregnancy for at least two years after last child;40 males with primary infertility (no children after at least five years of marriage and their active sperm count was zero). Detection of anti-ACL IgG and IgM was done using enzyme-linked immunosorbant assay (ELISA) commercial kits (Wendell/Shelm/Germany). All data were statistically analyzed. Results: The results revealed that the anti-ACL IgM positivity rate was significantly higher among women with primary fertility compared to healthy women (p = 0.006). Similarly, the anti-ACL IgM and anti-ACL IgG were significantly among women with secondary infertility compared to healthy women (p = 0.012) and (p = 0.038) respectively. Although the anti-ACL IgG and IgM positivity rate among men with primary infertility was higher than that of healthy control. However, the differences were failed to reach the statistical significance (p = 0.07) and (p = 0.31) respectively. Conclusion: The presence of high levels of anticardiolipin antibodies in women with primary and secondary infertility as well as in men with primary infertility may support the contention that these autoantibodies contribute to the infertility in both sexes.展开更多
