Many species of birds engage in elaborate courtship rituals. For example, the bowerbirds. The male bowerbird builds an elaborate structure, called a bower, and decorates it with various items like colorful feathers, berries, and shells. He then performs a dance to attract the female. This shows how nature has evolved unique ways for sexual reproduction.
Fireflies also have an interesting sex - related story. Male fireflies use their unique light patterns to attract females. Each species has its own distinct pattern. However, some other species have evolved to mimic the light patterns of other fireflies to deceive the males and prey on them. So, their 'sex signals' can be both for mating and for predation in a complex way.

Penguins also have fascinating mating stories. Emperor penguins, for example, the male penguin will incubate the egg while the female goes off to feed. This is a unique form of cooperation in their reproductive process. It shows how they have adapted to the harsh Antarctic environment in terms of their sexual and reproductive behavior.
Breastfeeding is a natural process mainly related to providing nutrition to infants. In terms of sex differences, women are biologically equipped with mammary glands for breastfeeding.

Females' hormonal changes during pregnancy and after childbirth play a key role in enabling breastfeeding, which is different from the biological functions related to sex in males.

Sure. There are quite a few. These success stories often involve women who have taken good care of their bodies over the years. They might have been careful about things like avoiding excessive stress and harmful substances. In some cases, it could be pure luck too.
