About You

Men with mild testosterone deficiency and whose weight is above the recommended range and/or who are physically inactive should be encouraged to consider low-risk lifestyle modifications followed by reassessment of testosterone levels, signs, and symptoms before deciding to start testosterone therapy. The main purpose of testosterone therapy is to return patients to normal physiological testosterone levels and provide relief of symptoms or signs. PSA secretion is an androgen dependent phenomenon, and the rise of PSA levels in patients on testosterone therapy is primarily dependent upon baseline total testosterone levels. Two studies145, 146 included in the evidence report that was developed in the support of this guideline suggest a link between radiation (in rectal cancer and prostate cancer patients) and low testosterone levels, however the studies are limited by heterogeneity in study populations, heterogeneity in radiation delivery, and the presence of confounders such as chemotherapy exposure. This is in contrast to patients with invasive prolactinomas, whose pituitary-gonadal axis may be permanently damaged, requiring testosterone replacement therapy even after normalization of prolactin levels.
Stress is a well-known trigger for telogen effluvium, so managing stress through relaxation techniques, exercise, or therapy can be beneficial. Yes, hair loss due to prolactinoma-related hormonal imbalances can affect both men and women. Does hair loss from prolactinoma affect both men and women? Will taking biotin supplements help with hair loss caused by prolactinoma? Are there any specific hair care products I should use if I have prolactinoma-related hair loss?
By shedding light on this complex relationship, healthcare professionals can better guide patients towards optimal hormonal health. This ensures that hormonal balance is restored and helps healthcare providers adjust treatment plans as needed. As a result, the production of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) – hormones that stimulate the testes to produce testosterone – is inhibited. While it is present in higher amounts in men, women also require testosterone for maintaining muscle mass, bone density, and overall well-being. Testosterone, a crucial hormone for both men and women, plays a vital role in various physiological functions, including muscle development, bone density, and libido.

Your healthcare provider will start with a prolactin (PRL) blood test. It might help screen for and catch a prolactinoma in its early phase. MEN1 is an inherited condition that can cause prolactinoma. The brain chemical dopamine helps suppress (stop) prolactin production. This is usually because the tumor prevents dopamine from reaching your pituitary gland. A prolactinoma is a benign (noncancerous) tumor (adenoma).
Another review noted that cabergoline therapy for 16 weeks significantly improved libido and sexual function in hyperprolactinemic patients, whereas bromocriptine did not show as much improvement in sexual side effects in that short timeframe. When prolactin levels are high and causing problems, treating the underlying hyperprolactinemia is a priority. In dopamine-resistant prolactinomas, adding an aromatase inhibitor (to block testosterone’s conversion to estradiol) has shown benefit in bringing prolactin levels under control.
These disruptions, rather than the prolactinoma itself, can sometimes impact hair health. However, it also influences other bodily functions, including reproduction and immune function. While indirectly possible, prolactinoma doesn’t directly cause hair loss in the same way as androgenetic alopecia (pattern baldness).
When you confirm the diagnosis, match the formulation to your life, and monitor smartly, you can expect meaningful gains in energy, sexual health, and body composition, without trading away safety. Screen for sleep apnea, diabetes, thyroid disorders, liver disease, and iron overload, treating these can nudge T upward and improve symptoms. Seven to nine hours of consistent sleep can increase testosterone and improve GH/IGF‑1 signaling. Blood pressure, lipids, sleep apnea, hematocrit, and smoking status deserve attention before and during therapy. If hematocrit climbs, your clinician may lower the dose, split injections, switch formulations, or pause therapy. Testosterone therapy suppresses sperm production, sometimes to zero, within months. Expect sexual benefits within weeks, energy and mood within 1–2 months, and body composition changes over 3–6 months alongside resistance training and protein intake.
Given the rarity of idiopathic HPRL in males, we present our experience with the diagnosis and treatment of 23 male patients with HPRL alongside normal testosterone levels. However, some men with sexual dysfunction and HPRL exhibit normal serum testosterone levels 3,10, suggesting mechanisms unrelated to testosterone/androgens can also contribute to the development of sexual dysfunction. In a clinical trial, the correction of prolactin levels in male patients with severe hyperprolactinemia using medications such as cabergoline (CAB) or bromocriptine (BRC) improved hypogonadism-related symptoms . However, when prolactin levels rise abnormally in both men and women, it can lead to a condition known as hyperprolactinemia, impacting hormonal balance and causing a range of symptoms. If prolactin is the culprit, therapy directed at lowering prolactin (with medications like cabergoline or bromocriptine) can not only normalize hormone levels but often restore sexual function and fertility. Severe hypothyroidism can cause a drop in total testosterone (by increasing prolactin and decreasing sex hormone binding globulin), while hyperthyroidism can increase SHBG and alter testosterone levels as well. Studies have documented improvements in testosterone levels and symptoms after prolactin-lowering therapy.
