During early fetal development, embryos of both sexes appear gender-neutral. As in cases without two sexes, such as species that reproduce asexually, the gender-neutral appearance is closer to female than to male. A fetus usually develops into a male if it is exposed to a significant amount of testosterone (typically because the fetus has a Y chromosome from the father). Otherwise, the fetus usually develops into a female, typically when the fetus has an X chromosome from the father, but also when the father contributed neither an X nor Y chromosome. Later at puberty, estrogen feminizes a young woman, giving her adult sexual characteristics.

If you like the taste of apple cider vinegar, then by all means, drink up! But if you are a normal human being who prefers not to chug pure acid, then you should know there's zero evidence that drinking the nasty stuff can actually help you drop pounds (or impart the laundry list of health benefits the Internet seems to associate with it, for that matter).
