Short answer: most guidelines use a total testosterone cutoff of about 300 ng/dL (≈10.4 nmol/L). Treatment is usually considered only if you have consistent low measurements plus symptoms of testosterone deficiency. Details and what that means for you Typical adult male total testosterone reference is roughly 300–1,000 ng/dL (10.4–34.7 nmol/L), though lab ranges vary. The Endocrine Society and American Urology Association commonly use a threshold of ~300 ng/dL. If total testosterone is below ~300 ng/dL on at least two morning (7–10 a.m.) measurements and you have symptoms (low libido, erectile problems, low energy/mood, loss of muscle mass, increased body fat, anemia, decreased bone density), treatment may be appropriate. Very low values (for example <200 ng/dL) are much more likely to cause symptoms and to prompt treatment or urgent evaluation. Important caveats Measure testosterone in the morning, while fasting if possible, and repeat the test because illness, stress, some meds, and acute medical problems can transiently lower levels. If total testosterone is borderline (250–350 ng/dL) or if you have conditions that change SHBG (obesity, diabetes, liver disease, thyroid disease), free testosterone or calculated bioavailable testosterone should be checked — labs report different reference ranges, so compare to your lab’s normal values. You also need further testing to find the cause: LH/FSH (to distinguish primary vs secondary hypogonadism), prolactin, and sometimes iron studies, sleep apnea screen, and metabolic testing. When NOT to give therapy and other concerns Don’t start exogenous testosterone if you have suspected or active breast or prostate cancer. Other contraindications/precautions include very high hematocrit, uncontrolled heart failure, and some recent cardiovascular events — these need individualized discussion with a clinician. Exogenous testosterone suppresses sperm production and can cause infertility. If you want to preserve or build fertility, alternatives include clomiphene citrate (commonly used off‑label) or hCG — discuss with a specialist. Common treatment options (examples and why) Topical gels: AndroGel, Testim — steady daily dosing, easy to use, but risk of transfer to others. Transdermal patch: Androderm — steady delivery, once-daily patch. Intramuscular injections: testosterone cypionate/enantate (often dispensed as Depo-Testosterone or generic testosterone cypionate) — less expensive, given every 1–3 weeks; can cause peaks and troughs. Long‑acting injections (testosterone undecanoate: Aveed/Nebido) provide more stable levels but require specific administration. Nasal: Natesto — multiple daily doses, lower systemic exposure between doses for some people. Fertility-preserving therapies: clomiphene citrate (Clomid, off‑label in men) or hCG (Ovidrel or prescribed hCG products) to raise endogenous testosterone without suppressing spermatogenesis as much. Monitoring if you start therapy Regular follow‑up with serum testosterone (to target mid‑normal range), hematocrit (risk of polycythemia), PSA, lipids, liver tests as indicated, and assessment of symptoms. Next step See your primary care doctor, urologist, or endocrinologist. Ask for a morning total testosterone test (and repeat it if low), plus LH/FSH and prolactin if the result is low. If you want, tell me your lab number(s) and symptoms and I can help interpret them and outline likely next steps.

Short answer Starting testosterone replacement therapy (TRT) in your 30s can help treat true hypogonadism, but it also carries important risks — the biggest being suppression of sperm production (fertility loss), increased red blood cell mass (polycythemia), effects on mood/skin, possible effects on lipids and sleep apnea, and the need for long‑term monitoring. Some cardiovascular and prostate safety questions remain debated. Before starting, get a full evaluation and discuss fertility plans. Key risks and side effects (what to watch for) Infertility / reduced sperm count: Exogenous testosterone suppresses LH/FSH → often causes oligospermia or azoospermia and testicular shrinkage. In many men this is reversible after stopping TRT but it can take months and may be incomplete. If you want children, discuss alternatives (see below) before starting. Testicular atrophy: Smaller testes are common because endogenous testosterone production is suppressed. Erythrocytosis / polycythemia: TRT commonly raises hematocrit. High hematocrit increases clot risk (stroke, pulmonary embolism). Many clinics aim to keep Hct <52–54% and will adjust dose or recommend phlebotomy if it rises. Mood, behavior, and libido changes: Can improve mood and libido, but some people experience irritability, aggression, or mood swings — sometimes related to peaks/troughs of certain formulations. Skin problems and acne: Especially early on or with higher doses. Gynecomastia: Aromatization of excess testosterone to estradiol can cause breast tissue growth or tenderness. Sleep apnea: Can worsen preexisting obstructive sleep apnea. Lipids and metabolic effects: TRT can lower HDL and affect lipids variably; overall cardiometabolic effects are mixed and individualized. Prostate effects: TRT can raise PSA and benign prostate volume. Current evidence does not prove TRT causes prostate cancer, but caution and baseline PSA screening are recommended in men at risk. Liver toxicity: Oral 17‑alpha alkylated androgens (not standard prescription TRT) can be hepatotoxic. Modern topical, injectable, or undecanoate forms have much lower hepatic risk. Injection-related: Some intramuscular regimens cause peak/trough symptoms (mood/fatigue fluctuations). Long‑acting formulations can reduce that. Special considerations in your 30s Evaluate cause first: In younger men, low T is often due to reversible causes (obesity, sleep apnea, certain meds, anabolic steroid use, opioids, pituitary issues). Treating the underlying cause can restore testosterone without lifelong TRT. Fertility is usually the primary issue: If you may want biological children, do not start standard TRT without discussing sperm preservation or alternative approaches that maintain spermatogenesis. Fertility-preserving alternatives and options Human chorionic gonadotropin (hCG): Stimulates the testes to make testosterone and preserves sperm production. Often used in men who want TRT benefits but also want fertility. Selective estrogen receptor modulators (SERMs) like clomiphene citrate (Clomid): Stimulate endogenous testosterone by increasing LH/FSH; commonly used off‑label for younger men with secondary hypogonadism and preserved fertility goals. Gonadotropin therapy (hCG + FSH) or referral to reproductive specialists if trying to conceive. If you’ve already used anabolic steroids, a specialist can advise on recovery protocols. Monitoring and safety steps if starting TRT Confirm diagnosis: At least two morning total testosterone measurements on different days, plus LH/FSH to distinguish primary vs secondary hypogonadism. Baseline tests: CBC/Hct, PSA, fasting lipids, LFTs, morning glucose/A1c, possibly prolactin and pituitary MRI if indicated. Ongoing monitoring: testosterone levels 4–12 weeks after start/after dose changes then every 3–6 months, CBC every 3 months first year then 6–12 months, PSA per urology guidelines, symptom review, and semen analysis if fertility is a concern. Keep Hct below target (commonly <52–54%). Manage rises by dose adjustment, switching formulation, or therapeutic phlebotomy. If you develop ischemic symptoms, new or worsening sleep apnea, breast changes, or significant mood changes, contact your clinician. Practical treatment/formulation notes Common prescription options: topical gels (AndroGel, Testim), transdermal patches (Androderm), short‑acting IM injections (testosterone cypionate or enanthate — brand Depo‑Testosterone is one example), long‑acting IM undecanoate (Aveed in the U.S., Nebido internationally), and subcutaneous pellets (Testopel). Injections often give the strongest rise in blood level but can cause peak/trough symptoms; weekly or split dosing can help. Gels give steadier levels but risk transfer to others by skin contact. Avoid oral 17‑alpha alkylated anabolic steroids (hepatotoxic) for TRT. Brands and services to consider For specialist evaluation: Mayo Clinic or Cleveland Clinic endocrinology/urology (reputable academic centers with experience in men’s health and fertility). For mainstream prescription products: AndroGel (AbbVie) and Testim (short‑acting topical gels), Androderm (patch), Depo‑Testosterone (testosterone cypionate injection), Aveed (testosterone undecanoate long‑acting IM), Testopel (pellets). Each has pros/cons (gels = steady but transfer risk; injections = dosing flexibility but peaks/troughs; long‑acting IM = less frequent dosing; pellets = surgical insertion). For telemedicine/primary TRT services (if you prefer remote care): companies like Hims or Roman offer convenient testing and prescriptions but vary in quality — get baseline labs and consider referral to an endocrinologist/urologist for complex or fertility‑related issues. Next steps I recommend Get confirmed low testosterone (two morning tests) and LH/FSH to determine cause. Discuss fertility plans — if you want kids, ask about hCG, clomiphene, or referral to an andrologist before starting TRT. See an endocrinologist or urologist with experience in male reproductive health for individualized risk/benefit assessment and a monitoring plan. If you start TRT, follow the monitoring schedule above and report any concerning symptoms immediately. If you want, tell me: Do you have children or plan to in the future, any current health problems (sleep apnea, clotting, heart disease), or lab values? I can help interpret options and suggest the most appropriate pathway.
