Abstract Background The utility of blood reproductive endocrine biomarkers for assessing or estimating semen quality was explored. Methods A cross-sectional study of 47 DDT exposed malaria vector control workers was performed. Tests included blood basal and post gonadotrophin releasing hormone GnRH lutenizing hormone LH follicle stimulating hormone FSH testosterone sex hormone binding globulin SHBG estradiol E2 and inhibin a questionnaire demographics and general medical history a physical examination and semen analysis. Semen parameters were determined using either or or both WHO or the strict Tygerberg criteria. Relationships between semen parameters and endocrine measures were adjusted for age duration of abstinence before sampling presence of physical abnormalities and fever in the last two months. All relationships between specific endocrine hormones were adjusted for age .
