Which event follows thelarche in the typical course of puberty for biological females?

The sequence of events during puberty for biological females typically begins with thelarche, which is the development of breast tissue. Following thelarche, pubarche, or the development of pubic and axillary hair, usually occurs. This event is associated with the increase in adrenal androgens due to the activation of the adrenal glands and is a sign that the body is undergoing the changes associated with puberty.

It's important to note that while ovarian follicle maturation and menarche are significant events within the puberty timeline, they generally occur after the onset of pubarche. For example, menarche, which is the first menstrual period, typically follows a few years after thelarche and is part of the later sequence of puberty events. Similarly, while the growth spurt is an essential physical development during puberty, it occurs concurrently but often intensifies around the same time as or slightly after pubarche. However, pubarche is reliably the immediate subsequent event that happens after thelarche, marking the transition in physical development more clearly.
