Sex Hormones

 

There are three types of sex hormones agonists: the Androgens or AAS like testosterone , the estrogens like estradiol and progestogens like progesterone.

 

– Estrogens

Estrogens (or oestrogens) are primary female sex hormones and play an important role in the regulation of many physiological processes of the reproductive system, such as ovulation, fertilization, implantation of the embryo and lactation. They can be produced synthetically and are used as a medication. Some estrogens are used as steroids. If animals are treated with estrogens, drug residues may remain in the animal’s meat and milk. Our reliable test systems can detect estrogen residues.

 

-Androgens

Androgens ( or androgenic steroids –AAS) are natural or synthetic steroid hormones that stimulate or control the development and maintenance of male characteristics by binding to androgen receptors. The group of androgens includes many synthetic molecules in addition to natural testosterone. If animals are treated with androgens, drug residues may remain in the animal’s meat and milk. Our test systems can reliably detect androgen residues.
