Vedclass · Answer

(A) Ovulation is the process of releasing a secondary oocyte from the ovary. It can be detected by several physiological changes:$1$. Basal body temperature $(BBT)$ rises by approximately $0.5^{\circ}F$ to $1.0^{\circ}F$ after ovulation due to the thermogenic effect of progesterone.$2$. The cervical mucus becomes thin, clear, and stretchy (spinnbarkeit), and when dried on a slide, it exhibits a characteristic 'fern pattern' due to high estrogen levels.$3$. Urinary excretion of estrogen metabolites (like estradiol) increases significantly just before ovulation.Since options $A$, $B$, and $C$ are all valid indicators, in a single-choice context, the rise in $BBT$ is a classic clinical indicator.
