Some examples of virilizing effects are growth of the clitoris in females and the penis in male children (the adult penis size does not change due to steroids ), increased vocal cord size, increased libido, suppression of natural sex hormones, and impaired production of sperm. Effects on women include deepening of the voice, facial hair growth, and possibly a decrease in breast size. Men may develop an enlargement of breast tissue, known as gynecomastia, testicular atrophy, and a reduced sperm count. The androgenic:anabolic ratio of an AAS is an important factor when determining the clinical application of these compounds. Compounds with a high ratio of androgenic to an anabolic effects are the drug of choice in androgen-replacement therapy (e.g., treating hypogonadism in males), whereas compounds with a reduced androgenic:anabolic ratio are preferred for anemia and osteoporosis, and to reverse protein loss following trauma, surgery, or prolonged immobilization. Determination of androgenic:anabolic ratio is typically performed in animal studies, which has led to the marketing of some compounds claimed to have anabolic activity with weak androgenic effects. This disassociation is less marked in humans, where all AAS have significant androgenic effects.A commonly used protocol for determining the androgenic:anabolic ratio, dating back to the 1950s, uses the relative weights of ventral prostate (VP) and levator ani muscle (LA) of male rats. The VP weight is an indicator of the androgenic effect, while the LA weight is an indicator of the anabolic effect.
Zoonosis, pasteurellosis can be transmitted to humans through cats.Other locations are possible, such as septic arthritis, meningitis, and acute endocarditis, but are very rare. Diagnosis
Diagnosis is made with isolation of Pasteurella multocida in a normally sterile site (blood, pus, or cerebrospinal fluid). Treatment
As the infection is usually transmitted into humans through animal bites, antibiotics usually treat the infection, but medical attention should be sought if the wound is severely swelling. Pasteurellosis is usually treated with high-dose penicillin if severe. Either tetracycline or chloramphenicol provides an alternative in beta-lactam-intolerant patients. However, it is most important to treat the wound. Animals
P. multocida causes numerous pathological conditions in domestic animals. It often acts with other infectious agents, such as  Chlamydia and Mycoplasma species and viruses. Environmental conditions (transportation, housing deficiency, and bad weather) also play a role. These diseases are considered caused by P. multocida, alone or associated with other pathogens:

Shipping fever in cattle and sheep  ("shipping fever" may also be caused by Mannheimia haemolytica, in the absence of P. multocida, and M. haemolytica serovar A1 is known as the most common cause of the disease. The pathologic condition commonly arises where the causative organism becomes established by secondary infection, following a primary bacterial or viral infection, which may occur after stress, e.g. from handling or transport.)
