INFERTILITY
However, as all hormones are mutually interlinked, one ought to know what to ask for, 'before a test', than ask a question after a test. Erection in man and the orgasmic delight are to a large part, dependent on neuronal and hormonal synchrony in effects. This also requires an intact responsive vasculature. Any erectile defect hence may portend a devastating hormonal/ vascular/ neuronal disease.
Similarly in women, persistent irregularity of cycles may be a harbinger of future infertility, hypertension, diabetes, cancer of breast, endometrium etc. Catching hold of the disease before it has ensnared the body prevents long term sequelae.
