Estrogen Blockers for Men: Everything You Need to Know

Because of this, they are used mainly in women who have gone through menopause already. Likewise, men with low zinc levels consistently display lower androgen level readings, illustrating a definitive association between these two micronutrients and sex hormone levels. Healthy young men who followed a zinc-restricted diet for 20 weeks experienced a drastic decrease in total testosterone levels, falling to a mere 25% of baseline values [5].

Yes, aromatase inhibitors are prohibited at all times as Hormone and Metabolic Modulators under the WADA Prohibited List. Since aromatase inhibitors prevent the conversion of androgens to estrogens, they artificially keep the level of androgens in the body very high, and androgens have many performance enhancing effects. Aromatase inhibitors are also sometimes used to minimize unwanted side effects from anabolic steroid use, such as breast growth in males. Note that breast cancer cell lines are a gold standard for studying estrogen Dostinex blockers since these cells express high amounts of the estrogen receptor. Thus, in vitro research using cancer cells from breast tissue is a primordial stage in discovering natural aromatase inhibitors like grape seed extract.

If you’d like to learn more about how to manage side effects from this medication, talk with your doctor or pharmacist.

SERMs are usually reserved for post-cycle therapy, though there are some men who use them successfully on-cycle in the place of an AI to block estrogen. Here’s what athletes and athlete support personnel need to know about aromatase inhibitors and their status on the World Anti-Doping Agency (WADA) Prohibited List. If your hormone levels meet the criteria for a diagnosis such as hypogonadism, they can also advise on treatment options. These can range from changing lifestyle factors (such as sleep and diet) to medications.

If you notice hair loss or hair thinning during your treatment with Arimidex, talk with your doctor. They may recommend ways to reduce this side effect or keep it from getting worse.

Side effects from Arimidex vary but can start right after your first dose. For example, you can experience headaches, nausea, or vomiting after only one dose of Arimidex.

  • Breast tumors that contain estrogen and/or progesterone receptors are sometimes called hormone receptor positive (HR positive).
  • As large interindividual variations exist, athlete biological passport (ABP) analysis is ongoing.
  • These results suggest potential roles for aromatase reaction products derived from androstenedione, warrant future research, and call for a re-evaluation of the initial aromatization hypothesis.
  • Adult testicular germ cells express aromatase, and estrogens play an important role in sperm maturation [1, 116].

Aromatase Inhibitors

Subjects in Group A received 2 daily oral dosages of aminoglutethimide (250 mg, 100 tabs; Nantong General Pharmaceutical Factory, China) at 500 mg/day for 3 consecutive days. All drugs were administered at 9 am every day, while the other dose in Group A was taken at 9 pm daily. Before treatment, the volunteers produced 4 daily blank urine samples (morning, noon, afternoon, and evening) for 7 days. During treatment and 3 successive days, urine samples were also collected at the above-mentioned 4 time points. From the 4th to 28th day after treatment, the morning urine samples were collected.

They were traveling for a business trip, and it was impossible for them to store the urine samples in the icebox and deposit them in time). Finally, 41 volunteers completed the excretion study, with each group comprising of at least 6 males and 6 females. Oysters, despite being rather simple in structure, actually rely on sexual steroids for reproduction. In a study examining the androgen metabolism of Crassostreagigas, a detected aromatase-like activity was suppressed by pharmacological compounds present within it. Aromatase might not sound dangerous, but it can actually cause harm in more ways than one – your sex drive, muscle mass, and even bone density can be severely affected. This side effect was only reported in people taking the drug for advanced breast cancer.
