Brief Summary
The purpose of this study is to develop new treatment options for osteoporosis in men. The Investigators will study two medications and three treatment regimens. First, risedronate (FDA approved) will be studied as monotherapy. Second, the investigators will study injectable parathyroid hormone (PTH 134, teriparatide; FDA approved), as a therapy for male osteoporosis. PTH, a naturally occurring hormone produced by the parathyroid glands, is one of the most important regulators of bone metabolism. The drug being studied in this protocol, teriparatide, is the first aminoterminal 34 amino acids of the native 84amino acid peptide. Teriparatide contains all of the classical biological activities of native PTH. In studies of postmenopausal women, in a small study of 23 men with osteoporosis and a larger study of 437 men treatment with teriparatide led to significant increases in bone density. Although teriparatide and actonel are now approved for osteoporosis in men additional studies of these medications are needed in order to establish how best to use these drugs. This study is focused on an entirely new treatment approach, namely the combination of two medications for the treatment of osteoporosis risedronate with teriparatide to evaluate whether combination therapy is superior to therapy with either medication alone. This study is also designed to assess the extent to which risedronate maintains increases in bone density after a course of mono or combination therapy.

Eligibility Criteria
You may qualify if:
- Males, ages 30-85 with osteoporosis.
- Osteoporosis can be due to hypogonadism, past steroid use, or idiopathic.
- Patients with hypogonadism can be included if their replacement dosage of testosterone has been stable for at least 18 months.
- Bone mineral density must be 2 or more standard deviations below (T-score 2.0) the young adult peak for men at the lumbar spine, the hip or the radius.
- Normal renal (glomerular filtration rate \>= 60 ml/min) and liver (less than or equal to twice the normal limits for ALT and AST) function.
You may not qualify if:
- Use of any specific osteoporosis drug in the previous 6 months.
- Known or suspected metabolic bone diseases (such as renal osteodystrophy, osteomalacia) other than osteoporosis.
- Preexisting hypercalcemia or an underlying hypercalcemic disorder, such as primary hyperparathyroidism.
- Secondary hyperparathyroidism.
- Paget's disease of bone or fibrous dysplasia. Teriparatide should not be given to patients with these conditions due to an increased risk of osteosarcoma.
- Patients with any elevations of alkaline phosphatase that are secondary to bone disease, as such individuals may be at risk for osteosarcoma.
- History or presence of any malignancy, except dermatological, but including melanoma. Known or suspected bone metastasis, or a history of skeletal malignancies.
- Prior radiation therapy. Patients with prior radiation therapy should be excluded from treatment with teriparatide.
- Any medical condition, which in the opinion of the investigator could preclude study participation, including but not limited to cardiovascular, gastric, renal and hepatic disorders, or abnormal PSA test. In particular, patients with active or recent (within the last 2 years) urolithiasis will be excluded.
- History of previous major bowel surgery including bowel resection.
- Oral use of systematic glucocorticoids for two or more weeks in the previous six months.
- Parenteral use of systemic glucocorticoids on more than two occasions in the previous six months.
- Use of anticonvulsant drugs.
- History of uncontrolled diabetes mellitus (Patient with Type 2 diabetes who have HbA1C\< 8 are permitted to be enrolled).
- Hypercalciuria (\> 4 mg/kg/day).
- +14 more criteria
