The correct answer is: The menstrual fluid can easily clot
During normal menstruation approximately $40 \mathrm{~mL}$ of blood and an additional $35 \mathrm{~mL}$ of serous fluid are lost. The menstrual fluid is normally non-clotting because a fibrinolysin is released alongwith necrotic endometrial material.
The cause of menopause is burning out of the ovaries. At about age 45 years only a few primordial follicles remain to be stimulated by FSH and LH. The estrogen production fall below a critical value and the gonadotropic hormones (FSH and $\mathrm{LH}$ ) are produced regularly from the pituitary so, there level increase in body.
