They have been very effective in treating breast cancer in women, but they have not been well-studied in men. Still, some doctors use them to treat advanced breast cancer in men, often combined with a luteinizing hormone-releasing hormone (LHRH) analog to turn off hormone production by the testicles (discussed below). This group of drugs includes anastrozole (Arimidex), letrozole (Femara), and exemestane (Aromasin). These drugs stop estrogen production by blocking an enzyme (aromatase) in fat tissue that converts male hormones from the adrenal glands into estrogen. While the negative impact of elevated BMI on hormonal parameters has been consistently reported, the same cannot be said for semen parameters.
Most people will experience some side effects when taking anastrozole, but there anabolic steroid tablets legal are ways to treat them at home.

Anastrozole is used to treat breast cancer in women after menopause. Some breast cancers are made to grow faster by a natural hormone called estrogen.
Effects of aromatase inhibition on luteinizing hormone release and testosterone production
- Overuse can lead to suppressed estrogen levels, affecting bone density and growth plates.
- Keep using birth control for at least 3 weeks after your last dose of anastrozole.

Long-term effects of continuing adjuvant tamoxifen to 10 years versus stopping at 5 years in 6,953 women with early breast cancer. This was once a common treatment for breast cancer in men, but it is now used less often because medicines such as LHRH analogs can now be used to lower androgen levels. In the meantime, clinicians can consider offering anastrozole to men with testosterone-luteinizing hormone ratios of 100 or greater before resorting to more expensive alternatives.
Anastrozole interactions
Due to these disappointing results, aromatase inhibitors are not recommended as a first-line treatment for gynecomastia in men. Peripheral androgen aromatization is enhanced in subjects with increased body mass index [40]. Massively obese men show markedly increased plasma estradiol concentrations and low testosterone concentrations [41].
The timing often aligns with your TRT schedule for convenience and effectiveness.

However, there are certain groups of people who should exercise caution or avoid taking this drug altogether.
Over the years compelling evidence has accumulated that in men estradiol has an important role in gaining and maintaining bone mass, closing of the epiphyses and feedback on gonadotrophin release. Aromatase inhibitors, mostly combined with agonists of gonadotrophin-releasing hormone proved effective for the prevention of premature epiphysial closure in boys with pubertas praecox of various etiologies. There is also evidence that aromatase inhibitors can be used in boys with idiopathic short stature and boys with constitutional delay of puberty to increase adult height. Aromatase inhibitors are not effective for the treatment of gynecomastia in pubertal boys and have limited efficacy for the prevention of gynecomastia in bicalutamide-treated men with prostate cancer. Although aromatase inhibitors increase FSH levels, there is no consistent evidence for a beneficial effect on spermatogenesis. In older men with so-called late-onset hypogonadism, aromatase inhibitors may emerge as an attractive alternative for traditional testosterone supplementation to improve testosterone levels.
