The differences between female hormones and male hormones may not be as specific as you might think. The definition of a hormone is a chemical substance produced by an endocrine gland that has a specific effect on the activities of other organs in the body. The major female and male hormones can be classified as estrogens or androgens. Both classes of male and female hormones are present in both males and females alike, but in vastly different amounts. Most men produce 6-8 mg of the male hormone testosterone (an androgen) per day, compared to most women who produce mg daily. Female hormones, estrogens, are also present in both sexes, but in larger amounts for women.
(plural testes ), 1704, from Latin testis "testicle," usually regarded as a special application of testis "witness" (see testament ), presumably because it "bears witness" to virility (cf. Greek parastates , literally "one that stands by;" and French slang témoins , literally "witnesses"). But Buck thinks Greek parastatai "testicles" has been wrongly associated with the legal sense of parastates "supporter, defender" and suggests instead parastatai in the sense of twin "supporting pillars, props of a mast," etc. Walde, meanwhile, suggests a connection between testis and testa "pot, shell, etc."
