Confirmed carcinogen producing liver tumors in women by ingestion. Experimental carcinogenic, neoplastigenic, and tumorigenic data.Enavid (CAS NO.8015-30-3) has human reproductive effects by ingestion: menstrual cycle changes or disorders; abnormalities of the uterus, cervix, and vagina; and changes in fertility. A human teratogen that causes developmental abnormalities of the urogenital system. Experimental reproductive effects. Mutation data reported. A steroid. When Enavid (CAS NO.8015-30-3) is heated to decomposition, it emits acrid smoke and fumes.
