Summary
Bone mineral density (BMD) loss associated with depot medroxyprogesterone acetate (DMPA) is reversible. Studies show BMD returns to baseline after DMPA discontinuation, suggesting no long-term fracture risk for women.
Area of Science:
- Reproductive Health
- Endocrinology
- Bone Metabolism
Background:
- Depot medroxyprogesterone acetate (DMPA) is a widely used, effective contraceptive.
- DMPA use is linked to decreased bone mineral density (BMD), raising osteoporosis concerns.
Purpose of the Study:
- To systematically review studies on BMD changes after DMPA discontinuation.
- To assess the reversibility of DMPA-associated bone loss.
Main Methods:
- Systematic review of PubMed-published studies (1996-2006).
- Included 10 primary clinical or observational studies.
- Evaluated BMD changes post-DMPA cessation.
Main Results:
- BMD consistently recovered to baseline levels after DMPA discontinuation across all age groups.
- Bone mineral density recovery was observed as early as 24 weeks post-therapy.
- BMD in former DMPA users was comparable to that of non-users.
Conclusions:
- DMPA-associated bone loss is reversible.
- The findings suggest DMPA use is unlikely to be a significant risk factor for long-term low bone density or fractures in older women.
- Further research is needed on actual fracture risk in DMPA users.

01:29Bone Disorders
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

01:17Hormones and Bone Tissue
The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

01:21Intrauterine Drug Delivery Systems
Controlled-release systems for intravaginal and intrauterine drug delivery have been developed primarily for the administration of contraceptive steroid hormones. These delivery routes circumvent first-pass hepatic metabolism, thereby enhancing bioavailability and allowing for reduced systemic dosages compared to oral administration. Such approaches contribute to improved therapeutic efficacy and patient compliance, particularly in long-term contraceptive regimens.Intravaginal Drug Delivery...
01:40Bone Remodeling
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.
01:27Fractures: Bone Repair
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
