👉 Pre-coloration is a process in which a person or animal, typically a female, does not produce any eggs until they are about 8 weeks old. This period of time is often referred to as "pre-ovulation," and it marks the beginning of ovulation (the fertilization of an egg by sperm). During this pre-ovulatory phase, the ovaries do not produce any eggs, but instead release mature follicles into the uterus.
