estrous

Estrous Control and Synchrony in Cattle Exogenous hormones can mimic the hormones of the natural estrous cycle in cattle.

For example, a cow is normally anestrous after giving birth, and an estrous synchrony regimen may be used to advance her first heat after calving.

Some estrous synchrony regimens may also induce or advance estrus in animals that aren’t cycling (they’re anestrous).

Female rats were not more variable at any stage of the estrous cycle than male rats.

Producers can group animals according to the phase of their estrous cycle, which reduces management burdens.

By administering exogenous hormones, producers can control and synchronize estrus in breeding heifers and cows as well as shorten their estrous cycles.

Most mammals go through some sort of estrous, but only a few menstruate.

The corpus luteum releases progesterone that counteracts prostaglandin, but toward the end of the estrous cycle the CL degrades into an inert corpus albicans.

> If you're utterly convinced that estrous and menstruation are the same You've completely missed my point.

The estrous cycle of dams is fairly complicated[1].

If you're utterly convinced that estrous and menstruation are the same, on the basis of some blood-like discharge occurring in both, then you might want to explore a career in academia.

Silencing of OxtrINs in the medial prefrontal cortex (mPFC) of female mice resulted in loss of social interest in male mice specifically during the sexually receptive phase of the estrous cycle.

Dogs don't have periods; they have estrous, commonly called "heat".

If people really want the one-sentence version: "One difference is that animals that have estrous cycles reabsorb the endometrium if conception does not occur during that cycle.

Yes, and even if the topic is just bleeding, humans aren't special, so it still shouldn't be "why do women bleed" but "why just primates, bats and one kind of shrew bleed during estrous cycle." Humans simply aren't special in that regard.

But after re-reading the article, it's not clear to me that women have a higher tolerance for pain, just that we require two types of receptors to be active to feel relief from morphine, and that the "complex" of proteins fluctuates with the estrous cycle.
