Joseph Bennington-Castro is a Hawaii-based contributing writer for Live Science and . He holds a master's degree in science journalism from New York University, and a bachelor's degree in physics from the University of Hawaii. His work covers all areas of science, from the quirky mating behaviors of different animals, to the drug and alcohol habits of ancient cultures, to new advances in solar cell technology. On a more personal note, Joseph has had a near-obsession with video games for as long as he can remember, and is probably playing a game at this very moment.
Some minor side effects include acne, oily skin, and a not so minor one in baldness. But the side effects don’t stop here. As I’ve said, anabolic steroids raise testosterone levels via synthetic androgens. This confuses your body and as a result, it decreases and even stops your body’s own secretion of testosterone. Thus, during “off” cycles, testosterone becomes so low that the users have a hard time holding on to their gains resulting in a rapid loss of strength and muscle. Although anabolic steroids don’t cause the same “high” as other illegal drugs, this concept makes it prone to abuse and addiction.
Like tachyzoites, merozoites divide quickly, and are responsible for expanding the population of the parasite inside the cat intestine prior to sexual reproduction.  When a feline definitive host consumes a tissue cyst (containing bradyzoites), bradyzoites convert into merozoites inside intestinal epithelial cells. Following a brief period of rapid population growth in the intestinal epithelium, merozoites convert into the noninfectious sexual stages of the parasite to undergo sexual reproduction, eventually resulting in the formation of zygote-containing oocysts.
