ABSTRACT
Objective@#This study aimed to investigate the impact of hyperandrogenism (HA) on the outcomes of ovulation induction (OI) using gonadotropin and intrauterine insemination (IUI) in patients with polycystic ovary syndrome (PCOS). @*Methods@#This was a retrospective cohort study including 415 patients undergoing OI using gonadotropin and IUI treatment between January 2018 and December 2020 at a single infertility center. Baseline characteristics, clinical and laboratory parameters, and pregnancy outcomes were investigated. @*Results@#Among the study population, there were 105 hyperandrogenic (25.3%) and 310 non-hyperandrogenic patients (74.7%). The live birth rate was lower in the HA group than in the non-HA group, but this difference did not reach statistical significance due to the limited sample size (14.3% vs. 21.0%, relative risk=0.68; 95% CI, 0.41–1.14, p=0.153). No predictive factors for live birth were identified through logistic regression analysis. @*Conclusion@#HA did not negatively affect the outcomes of OI using gonadotropin and IUI cycles in Vietnamese women with PCOS. The result may not be applicable elsewhere due to the large variation in the characteristics of women with PCOS across races and populations.
ABSTRACT
A study on the pulmonary ventilation of 125 patients workers (male: 96, ages of 30-35 and working duration: 7-35 years) who were working in the environment with free silicon level that exceed the allowed standard has shown that there was a normal ventilation but there was a reduction of maximal flows among worker who were working in the environment with free silicon level that exceeded the allowed standard. There was a reduction of pulmonary ventilation and maximal flows among worker with silicosis type P.
