What are the means of investigation of ovaries?

US (volume and structure), morning thermal curve (for luteal phase, look for monophasic amenorrhea) Endocrine function test (smears and biopsies estimating estrogen impregnation) Progestative test (duphaston for 10 days then progesterone, if bleeding occurs hen we have normal estrogen else we dont have) Hormonal measurement (not very useful, use only androgens) Karyotype (mainly turner (primary amenorrhea)
