The given graph shows the hormonal changes during a normal menstrual cycle in human female. What would be a likely consequence if the hormone represented by graph Q is lacking in an adult female?\

Professor PC Thomas Classes · Answer

(a) : The graph P represents changes in estrogen level and graph $Q$ represents changes in progesterone level during a normal menstrual cycle. Progesterone is required for the maintenance of uterine lining which is needed to implant the fertilised ovum. Thus, if progesterone is lacking in an adult female, her uterine lining might not be stable to support an implanted embryo.
