During menopause, what process gradually occurs in the female reproductive system?

During menopause, the female reproductive system experiences a gradual decline in hormone production, particularly estrogen and progesterone. This process signals the end of a woman's reproductive years, leading to various physical changes and symptoms such as hot flashes, night sweats, mood changes, and alterations in menstrual cycles.

As the ovaries age, their ability to produce these hormones diminishes, resulting in irregular menstrual cycles that eventually cease entirely. This hormonal decrease is a natural part of aging and is a key characteristic of the menopausal transition, marking significant changes in a woman's body and reproductive health.

The other choices do not accurately reflect the physiological changes that occur during menopause. Increased ovulation would be contrary to the natural decline in ovarian function, and increased hormone production is not characteristic of this stage, as it is defined by diminished hormone levels. The continuation of menstrual cycles also does not align with the definition of menopause, which is recognized by the cessation of menstruation.
