Younger men arrive at the andrology clinic with the symptoms of testosterone deficiency and one particular worry: that treating it will cost them the chance of fatherhood. That worry is well founded, and it is the reason human chorionic gonadotropin — hCG — is discussed at all. This article explains what hCG does, the single condition that decides whether it can work for you, and what still has to be watched while you are on it.

The one thing that decides whether hCG can work for you

hCG behaves like luteinising hormone: it signals the Leydig cells inside the testis to produce testosterone. It is a message, not a substitute. That means it can only work if there is something there to receive the message.

안 secondary hypogonadism, the problem is upstream — the pituitary is not sending enough signal, so LH and FSH are low or inappropriately normal while testosterone is low. The testes themselves are capable. hCG supplies the missing signal and can work well.

안 primary hypogonadism, the testis itself has failed. The pituitary is already shouting — LH and FSH come back high — and the testis is not answering. Adding more of the same signal achieves nothing. hCG does not work in primary testicular failure, and no amount of it will change that. This is why the blood tests come before the prescription, and why LH and FSH matter as much as the testosterone number itself.

An earlier version of this article did not make that distinction and framed hCG as an option in age-related testosterone decline generally. That was too loose, and it is corrected here.

Symptoms that prompt testing in the first place

Testosterone deficiency is diagnosed on symptoms 및 confirmed low morning blood levels — not on either alone. The symptoms fall into three groups.

1. Sexual — reduced desire, erectile difficulty, fewer morning erections.
2. 물리적 인 — increased abdominal fat, loss of muscle mass and strength, fatigue.
3. Psychological — low or unstable mood, poor concentration, disturbed sleep.

None of these is specific to testosterone. Poor sleep, depression, thyroid disease, heavy alcohol use and obesity all produce the same list, which is why a single low reading on a man who slept badly is not a diagnosis.

Why fertility is the whole argument

Testosterone given from outside the body switches off the pituitary signal that drives the testis. Testosterone concentration 안에 the testis then collapses, and sperm production falls with it — often to zero. A man on testosterone therapy should assume he is infertile while he is on it.

hCG does the opposite. By driving the testis rather than replacing it, intratesticular testosterone is maintained and sperm production continues. For a man who has not finished having children, that difference is the entire point.

What hCG does, and what it does not do

What it is	Human chorionic gonadotropin, a hormone that acts on the same receptor as luteinising hormone
How it works	Signals the Leydig cells of the testis to make testosterone, rather than supplying testosterone from outside
Requires	A testis that still responds — no effect in primary testicular failure
Sperm production	Preserved, because testosterone inside the testis is maintained. This is its main advantage over testosterone therapy
Oestradiol	Often rises, sometimes enough to cause breast tenderness or enlargement. Monitored, and treatable
Haematocrit and PSA	Can rise, as with anything that raises testosterone. Both are monitored
Administration	Injection, given more frequently than long-acting testosterone. Dose and interval are the prescriber’s decision, not a fixed recipe
Time before judging it	Several months of consistent use

A correction to the earlier version of this article

The table published here previously stated that hCG does not affect oestradiol, haematocrit or PSA. That was wrong and has been corrected. Because hCG raises testosterone within the testis, a proportion of it is converted to oestradiol locally, and oestradiol commonly rises more on hCG than on testosterone therapy. Rising haematocrit and rising PSA are possible with any treatment that raises testosterone. The practical consequence is the opposite of what the old table implied: blood monitoring is required on hCG, not optional.

hCG is not the only fertility-sparing option

Where the pituitary signal is the problem, there is more than one way to restore it, and the choice is made on the individual picture rather than on a preference for injections or tablets.

• 클로미펜 시트르산염 — taken by mouth, it removes oestrogen feedback at the pituitary so the man produces more of his own LH and FSH. Convenient, and it needs a pituitary that works.
• hCG — injected, and it bypasses the pituitary entirely by acting directly on the testis. This is what makes it usable where clomiphene is not.
• An aromatase inhibitor — used where oestradiol is disproportionately high, often alongside one of the above rather than instead of it.
• hCG added to testosterone therapy — for a man who needs testosterone but wants testicular function maintained, the two are not always an either-or choice.

All four are prescribed and monitored in clinic. If fatherhood is still planned, say so at the first consultation rather than after treatment has started — it changes which of these is chosen. See also the testosterone therapy service page.

Switching from testosterone therapy to hCG

This can be done, and it is done — usually when a man’s circumstances change and children become the priority. But an earlier version of this article said the switch happens without complication, and that was too comfortable a description.

After a period on testosterone, the pituitary signal has been suppressed and the testes have been idle. Recovery is not instant. There is usually a stretch during which testosterone is falling from the old treatment before the new one has taken effect, and symptoms can return in the gap. Sperm production takes months, not weeks, to return, and after long-acting preparations it takes longer still. It is a planned transition with blood tests along the way, not a swap.

정기 진료 대신 주의를 기울여야 하는 증상

Get medical attention the same day for any of the following while on hormonal treatment. In an emergency in Thailand, call 1669.

• Chest pain, sudden breathlessness, or pain and swelling in one calf — a thickened blood is a recognised risk of any testosterone-raising treatment.
• Sudden weakness down one side, difficulty speaking, or facial droop.
• Sudden severe testicular pain, or a new testicular lump.
• New headaches with visual change, or discharge from the nipple — these point to the pituitary and are a reason to look upstream rather than simply treat the low testosterone.

Breast tenderness or enlargement is not an emergency but should not be tolerated silently either — it usually means oestradiol needs checking, and it is manageable.

자주 묻는 질문 (FAQ)

Q1: hCG란 무엇이며 남성 성선기능저하증에서 어떻게 작용하나요?

Human chorionic gonadotropin acts on the same receptor as luteinising hormone, signalling the Leydig cells of the testis to produce testosterone. Unlike testosterone therapy, which supplies the hormone from outside and switches the testis off, hCG drives the testis to work.

Q2: Will hCG work for anyone with low testosterone?

No, and this is the most important thing to understand about it. hCG works in secondary hypogonadism, where the pituitary signal is inadequate but the testis is capable. It does not work in primary hypogonadism, where the testis itself has failed and LH and FSH are already high. The blood tests distinguish the two before any treatment is chosen.

Q3: Does hCG really preserve fertility?

It maintains testosterone concentration inside the testis, which is what sperm production depends on, so it does not cause the collapse in sperm counts that testosterone therapy does. That is a genuine and important advantage. It is not the same as a guarantee of fertility — a semen analysis is what answers that question for an individual man.

Q4: Does hCG need blood monitoring?

Yes. Oestradiol commonly rises on hCG, sometimes enough to cause breast tenderness or enlargement, and haematocrit and PSA can rise as they can with any treatment that raises testosterone. An earlier version of this article stated the opposite, and that has been corrected.

Q5: How long before I know whether it has worked?

Several months of consistent treatment before a fair judgement can be made, with blood tests along the way. Desire and energy tend to respond earlier and more reliably than erectile function does.

Q6: Can I switch from testosterone therapy to hCG?

Yes, and it is commonly done when fatherhood becomes the priority — but it is a planned transition rather than a straight swap. The pituitary and testes have been suppressed, symptoms can return during the gap, and sperm production returns over months rather than weeks, longer after long-acting preparations.

Q7: Should I buy hCG online and manage it myself?

No. Beyond the question of what is actually in an unregulated vial, hCG used without knowing whether the hypogonadism is primary or secondary is at best useless and at worst delays the diagnosis of a pituitary problem that needed finding. It also requires monitoring that self-treatment does not provide.
