Subcutaneous injectables that keep the testes active — often added to testosterone therapy to help preserve sperm production and testicular size. Prescribed online after real bloodwork and reviewed by a licensed provider.
HCG and gonadorelin are injectables that keep the testes working — directly, in the case of HCG, or by prompting the pituitary, in the case of gonadorelin. They are most often added to testosterone therapy, which can otherwise quiet the body's own signal and shrink the testes over time. Guided by symptoms plus bloodwork, they help preserve sperm production and testicular size, and are also used to support fertility.
HCG mimics LH and gonadorelin prompts LH and FSH — both keep the testes producing rather than going idle.
Testosterone therapy can suppress sperm production; adding HCG or gonadorelin is a common way to help keep fertility on the table.
By keeping the testes stimulated, these injectables help counter the testicular shrinkage that can accompany testosterone therapy.
Your provider sets and adjusts the protocol based on follow-up bloodwork, so treatment tracks your real numbers.
Start with real bloodwork so a provider can review your testosterone, LH, FSH, and related markers.
A licensed provider reviews your symptoms, labs, and fertility goals, then prescribes HCG or gonadorelin at a starting dose if it's appropriate.
Follow-up labs track your response so your provider can fine-tune the schedule and keep you in a healthy range.
HCG and gonadorelin are for men who are on or considering testosterone therapy and want to preserve their fertility or testicular size, and for men seeking fertility support. As with any hormone therapy, the plan is confirmed by symptoms plus bloodwork — not by symptoms alone.
They're often chosen by men who are trying to conceive now or later, or who want to keep their body's own production stimulated while on testosterone. Your provider will help decide whether HCG, gonadorelin, or another approach fits your labs and goals.
