Erectile dysfunction (impotence) is the inability to get and keep an erection firm enough for sex.It is described as the condition where a man is showing persistent or recurrent inability to attai or maintain penile erection sufficient for sexual performance. Erectile dysfunction symptoms might include persistent Trouble getting an erection, Trouble keeping an erection, reduced sexual desire. Sexual dysfunction is highly prevalent in men than women. All studies demonstrate a strong association with age, even when data are adjusted for the confounding effects of other risk factors.
Antimüllerian hormone (AMH) and antral follicle count (AFC) were the only independent predictors for low and excessive ovarian response. In prediction of excessive response, the area under the receiver operating characteristic curve [AUC (95% CI)] for AMH was 0.890 (0.832-0.947) and 0.897 (0.829-0.964) for AFC. The optimal thresholds for identifying excessive responders were 3.52 ng/mL for AMH (sensitivity 89.5, specificity 83.8) and 16 for AFC (sensitivity 80.0, specificity 84.5). AMH and AFC also predicted low ovarian response: AUCs AMH 0.836 (0.783-0.889) and AFC 0.830 (0.767-0.894). The optimal thresholds for predicting lowresponse were 1.37 ng/mL for AMH (sensitivity 74.1, specificity 77.5) and 8 for AFC (sensitivity 72.2, specificity 84.6). For both excessive and low ovarian responses, a logistic regression model combining the biomarkers was associated with improved discrimination. AMH and AFC are the best predictors for low and excessive response in women treated with corifollitropin alfa in an antagonist protocol. Using AMH and AFC to select suitable candidates for treatment with corifollitropin alfa may result in a safe and convenient stimulation.
