Do rats go through menopause?

Mice and rats are sexually mature by 3–6 months of age and approach the endocrine equivalent of human perimenopause by 9 months of age (6, 69, 70). Their reproductive senescence transition occurs between 9 and 12 months of age by which time they are reproductively senescent.

Do mice go through menopause?

How do mice induce menopause?

Cyclicity studies (daily vaginal cytology) have shown that, when B6C3F1 female mice are dosed for 10 consecutive days, menopause occurs by approximately day 135 after the onset of dosing (FIGURE 2A).

Do mice have estrogen?

In mice, for example, the estrous cycle varies from 2–7 days, and decreased cycling is observed in older females (>13 months old).74 Female rodents do not go through a significant decline in estrogen that resembles human menopause, and there are no changes in estrogen levels between young C57Bl6 mice and older (14 …
