- Do animals other than humans have menstrual cycles?
- Q:
- A: Not in the same way humans do, no. Since some people here are obviously confused about what oestrus and menstruation actually are, I will explain.Oestrus, commonly called being 'in season' or 'in heat', is the only time an animal can become pregnant - it is when the womb lining is thickened in preparation for pregnancy, and the ovaries have either released eggs or are about to release them with the stimulus of mating. In the majority of species, oestrus is the only time the animal feels sexual desire, since it is the only time pregnancy can occur and it would be pointless to mate at any other time. We humans are rare in that we are unaware ourselves of being in oestrus, though it happens once a month - we must work out where we are in our cycle or use ovulation strips to tell us when the best time to try for a baby is.In humans, if a woman does not become pregnant during oestrus, the womb lining and unfertilised egg are discarded - this is menstruation, or 'having a period'. This does not happen in animals - they reabsorb the womb lining into their bodies instead of shedding it. When some animals, such as dogs, are in oestrus, they produce a bloody discharge, which may lead some people to think the animal is having a period. This is not the case - the animal is ready to conceive, not getting rid of its womb lining after failing to conceive.
- Do all animals have a menstrual cycle?
- Q: I know dogs have theirs but I don't know about any other animals. If so, which other animals do have a menstrual cycle?
- A: Yes!!! Menstrual cycles occur in humans and primates, there are very few other mammals that have actual menstrual cycles. In other mammals it is referred to as estrus, which is actually somewhat different than a menstrual cycle. One difference is that animals that have estrous cycles reabsorb the endometrium if conception does not occur during that cycle. Animals that have menstrual cycles shed the endometrium through menstruation instead. Another difference is sexual activity. In species with estrous cycles, females are generally only sexually active during the estrus phase of their cycle (see below for an explanation of the different phases in an estrous cycle). This is also referred to as being "in heat." In contrast, females of species with menstrual cycles can be sexually active at any time in their cycle, even when they are not about to ovulate. Humans, unlike some other species, do not have any obvious external signs to signal receptivity at ovulation (concealed ovulation). Research has shown however, that women tend to have more sexual thoughts and are most prone to sexual activity right before ovulation.Poodles are dogs which have estrus cycles.
