Detailed explanation-1: -Primary osteoporosis is the most common form of osteoporosis. It is divided into juvenile and idiopathic osteoporosis; idiopathic osteoporosis can be further subdivided into postmenopausal (type I) and age-associated or senile (type II) osteoporosis. Postmenopausal osteoporosis is primarily due to estrogen deficiency.

Detailed explanation-2: -Primary Type I Osteoporosis Type I is generally referred to as postmenopausal osteoporosis, as this is more commonly seen among women (six times more frequent) who have gone through menopause, resulting in a drop in levels of estrogen.

Detailed explanation-3: -Unlike postmenopausal osteoporosis which is linked to menopause in women, senile osteoporosis is due to aging, hence, affecting both men and women.

Detailed explanation-4: -Type II (senile) osteoporosis (Fig. 4) occurs both in men and in women who are more than 75 years old. In Type II osteoporosis, there is cortical and trabecular bone loss and the patients present with fractures of the hip, pelvis, humerus, and vertebrae.
