Abstract: Primary and secondary osteoporosis in a female or a male mammal is treated by administering thereto a nitric oxide synthase substrate, a nitric oxide donor or both, optionally; in further combination with one or more of an estrogen, a progestin, an anabolic steroid. Nitric oxide substrate or donor also can be combined with one or more of other medications acting on bone, such as bisphosphonate, calcitonin, fluoride, androgen and other novel therapeutic agents. Either nitric oxide donor or substrate by itself or combination with other medications as described above can be used in both women and men, (preferably human) for prevention and treatment of osteoporosis and other metabolic bone disorders.

Abstract: The present invention provides a method for counteracting preeclampsia, eclampsia of pregnancy and preterm labor in a pregnant female mammal treated by administering thereto calcitonin gene-related peptide (CGRP) or its analogues including CGRP/adrenomedullin or their peptide or receptor-based analogues, or in combination with a progestin, and with or without a nitric oxide substrate, or a nitric oxide donor or both, optionally in further combination with one or more of a cyclooxygenase inhibitor, a PGI.sub.2 -mimetic, a thromboxane (TXA.sub.2) inhibitor, a compound possessing TXA.sub.2 -agonistic, and TXA.sub.2 -inhibiting properties, a compound possessing TXA.sub.2 -antagonistic and PGI.sub.2 -mimetic activities, and a TXA.sub.2 antagonist. CGRP, progesterone and some of the nitric oxide substrate and donor compounds are naturally occurring compounds. As such these agents do not have the same toxicity and allergy problems as the foreign substances that are currently used for similar purposes.

Abstract: Inhibition of ovulation in a female may be achieved by administering a nitric oxide synthase inhibitor, alone or in combination with one or more of a progestin, an estrogen, and an LH-RH antagonist, thereby preventing conception. The stimulation of ovulation in a female may be achieved by administering a nitric oxide source, optionally in further combination with one or more of clomiphene, a gonadotropin, and an LH-RH agonist.

Abstract: Inhibition of ovulation in a female may be achieved by administering an arginine derivative which acts as a nitric oxide sythase inhibitor, alone or in combination with one or more of a progestin, an estrogen, and an LH-RH antagonist, thereby preventing conception.
