Answer 1

e. Delay of menarche past the age of 16 Primary amenorrhea is the absence of the onset of menstruation by age 16 or older, characterizing a delay in the first menstrual period.

Step-by-step explanation:

The condition that characterizes primary amenorrhea is e. Delay of menarche past the age of 16. Menarche is the term for the first menstrual period in females, which signifies the beginning of a female's reproductive years. The average age for menarche in the United States is approximately 12.5 years, but it can normally occur anywhere between ages 8 and 16. Thus, primary amenorrhea is defined as the absence of the onset of menstruation by the age 16 or older.

Primary amenorrhea is characterized by delay of menarche past the age of 16.Menarche is the first menstrual period that occurs in females around the age of 12 or 13. However, there is considerable variation, and menarche can occur as early as eight years of age or as late as 16 years of age and still be considered normal. If menarche is delayed past the age of 16, it is characterized as primary amenorrhea.
