The female body goes through monthly cycles of fertility with changing hormones and body functions. On the other hand, the male body does not go through these cycles of change and instead remain consistent. Why do you think that is?

Males will forever stay fertile while females will go through menopause and become infertile. women drop one egg a month which happens before the menstrual cycle. males sperm is constantly being matured and produced!
hope this helps

1.)dr. natterson- horowitz came to realize that their isn't much of a difference between animals and humans. just like humans, animals can suffer from illnesses and diseases like breast cancer, self injury, anxiety, and many more. she also discovered how they even treated and performed surgical procedures on animals just as if the animal it self were human. the los angeles zoo called dr. natterson- horowitz because they knew that she was a doctor and that  she would be able to recognize what was wrong with the gorilla. they knew that humans and gorillas were similar, so instead of calling another veterinarian, they called a doctor.
