There are also sex-specific side effects of AAS. Development of breast tissue in males, a condition called gynecomastia (which is usually caused by high levels of circulating estradiol ), may arise because of increased conversion of testosterone to estradiol by the enzyme aromatase . [82] Reduced sexual function and temporary infertility can also occur in males. [37] [83] [84] Another male-specific side-effect that can occur is testicular atrophy , caused by the suppression of natural testosterone levels, which inhibits production of sperm (most of the mass of the testes is developing sperm). This side-effect is temporary; the size of the testicles usually returns to normal within a few weeks of discontinuing AAS use as normal production of sperm resumes. [85]

By the time newspapers began assigning specialists to focus on PED reporting, they had also grown more committed to the job of peeling back the curtain. By 2003, it was no longer a curiosity for a baseball writer to ask a player if he was using PEDs. Richard Justice, who had become a columnist at the Houston Chronicle , said he asked the Astros’ Jeff Bagwell two or three times. “He would deny it,” Justice said. “I’d say, ‘HGH?’ ‘No.’ ‘Steroids?’ ‘No.’
