The progesterone hormone in animals has important physiological effects. Progesterone can promote the maturation of sexual organs and the appearance of secondary sexual characteristics in female animals, and maintain normal sexual desire and reproductive functions. Progesterone is often used in animal husbandry to promote estrus and reproduction in animals to improve economic efficiency. However, the abuse of steroid hormones such as progesterone can lead to abnormal liver function, and anabolic steroids can cause adverse effects such as high blood pressure and heart disease in athletes.
