Urine and blood sampling A urinary test will be sampled for test of hCG, human Chorionic Gonadotropin (pregnancy), at time of inclusion. A blood sample, for serum and plasma, will be drawn at inclusion and directly after the treatment period. The blood samples will be analysed directly for estrogen, progesterone, testosterone, sexual binding globulin, thyroid stimulating hormone and prolactin and thereafter discarded.
