Short answer
- If you want to preserve or improve fertility (or you have suspected secondary hypogonadism), try a fertility-sparing option first — a SERM like enclomiphene (or the commonly used off‑label alternative, clomiphene/Clomid).
- If you have primary testicular failure (high LH/FSH) or very symptomatic low T and you do not want future fertility, testosterone replacement therapy (TRT) is usually the appropriate first choice.
Why (plain explanation)
- Enclomiphene (a isomer of clomiphene; marketed as Androxal in development) and clomiphene citrate (Clomid/Serophene, widely available) are oral selective estrogen receptor modulators (SERMs). They act at the hypothalamus/pituitary to increase LH and FSH, which raises your own (endogenous) testosterone and typically preserves or improves sperm production.
- TRT (topical gels like AndroGel/Testim/Fortesta, injections like Depo-Testosterone or Nebido, or pellets Testopel) gives you exogenous testosterone. It reliably raises serum T and improves symptoms, but it suppresses LH/FSH and usually reduces sperm production and testicular size — so it impairs fertility.
Which to consider first — practical rule of thumb
- Desire fertility (current or future) or low/normal LH: try SERM/enclomiphene or hCG-based therapy first. Clomiphene (Clomid) is inexpensive and commonly used off‑label; enclomiphene (Androxal) showed similar intent but is less widely available in many countries.
- Lab pattern showing primary hypogonadism (low T with high LH/FSH), or severe symptoms where quick symptom control is required and fertility is not desired: TRT is usually more effective.
- If you’re unsure, start with a proper workup (see below) and discuss with an endocrinologist or urologist who treats male reproductive health.
Other options and notes
- Human chorionic gonadotropin (hCG; brands include Pregnyl, Novarel, Ovidrel) can be used to stimulate testicular testosterone production and maintain fertility — often used alone or with TRT when fertility is desired.
- Monitoring and risks: baseline and follow-up labs (morning total testosterone, LH, FSH, CBC, PSA, prolactin, SHBG as indicated). TRT risks include erythrocytosis (raise hematocrit), acne, possible worsening of sleep apnea, and reduced fertility. SERMs can cause mood changes, visual symptoms, and — less commonly — thrombotic risk; evidence on cardiovascular effects is mixed.
- Contraindications: known prostate or male breast cancer generally rule out TRT; discuss SERMs if you have other hormone-sensitive conditions.
Practical next steps
- Get morning total testosterone repeated (two measurements), LH, FSH, prolactin, CBC and PSA as indicated.
- If labs show secondary hypogonadism (low T with low/normal LH/FSH) and you want fertility, discuss clomiphene or enclomiphene with a specialist.
- If labs show primary hypogonadism (high LH/FSH) or you do not want fertility and have significant symptoms, discuss TRT options (gels, injections, long‑acting undecanoate).
- If fertility is important but testosterone is very low, consider hCG or combined protocols with a specialist.

- your age, whether you want kids, any current lab values (T, LH, FSH), and symptoms — I can give more tailored guidance and which specific medications/brands to discuss with your doctor.
