Spermarche refers to which event?

Onset of breast development

Onset of pubic hair growth

Onset of puberty in females

Appearance of spermatozoa in seminal fluid

Spermarche marks the first time sperm appear in semen, signaling the start of sperm production and male fertility during puberty. This is a male-specific puberty milestone that follows earlier development like testicular growth and other secondary sexual changes. The other options describe female puberty signs (breast development, pubic hair) or a general female puberty event, not the male event of sperm appearing in seminal fluid. So the appearance of spermatozoa in seminal fluid best fits spermarche.
