ယခင်ဆောင်းပါးတစ်ခုတွင် ကြွက်သားအတွင်းသို့ Testosterone ထိုးနည်း (intramuscular, IM) ကို ပြသခဲ့ပါသည်။ ယနေ့တွင် ကမ္ဘာတစ်ဝှမ်း ရေပန်းစားလာသော ပိုမိုနူးညံ့၍ လွယ်ကူသော ရွေးချယ်စရာတစ်ခုကို မိတ်ဆက်ပေးလိုပါသည် — Testosterone အရေပြားအောက် ထိုးဆေး (SC) — ကြွက်သားအတွင်းနက်နက်သို့မဟုတ်�’�ဘဲ အရေပြားအောက်ရှိ အဆီအလွှာသို့ ထိုးခြင်းဖြစ်သည်။

Testosterone အစားထိုးကုထုံး ခံယူနေသော ကျွန်ုပ်၏ လူနာအများစုသည် ရိုးရာ IM ထိုးဆေးကို မသက်မသာဖြစ်ကြပြီး၊ အချို့မှာ တင်ပါးသို့မဟုတ် ပေါင်ကြွက်သားသို့ ထိုးနိုင်ရန် မိသားစုဝင်တစ်ဦး၏ အကူအညီ လိုအပ်ကြသည်။ ဝမ်းသာစရာသတင်းမှာ ခေတ်မီသုတေသနက အရေပြားအောက်ထိုးနည်းသည်လည်း တူညီစွာ ထိရောက်ကြောင်း — ထို့ပြင် များသောအားဖြင့် များစွာ ပိုမိုသက်တောင့်သက်သာရှိပြီး ကိုယ်တိုင်ထိုးရန် ပိုလွယ်ကူကြောင်း ပြသထားသည်။

One thing to be clear about before the technique. This guide is written for men who are already under the care of a doctor for testosterone deficiency and who hold a prescription. Testosterone is a prescription-only medicine, and the decision to start it rests on symptoms together with blood tests taken on more than one morning — never on a description of how the injection is performed. If you are using testosterone, or a testosterone-like compound, obtained online, from a gym or from any source other than a pharmacy, technique is the smallest of the problems: those products are frequently mislabelled, and the reasons are set out in a separate article on unregulated men’s health products.

အရေပြားအောက် ထိုးနည်းကို အဘယ်ကြောင့် စဉ်းစားသင့်သနည်း။

နှစ်ပေါင်း ၈၀ နီးပါးကြာ ကြွက်သားအတွင်း (IM) Testosterone ထိုးဆေးသည် စံနှုန်းဖြစ်ခဲ့သည်။ ၎င်းတို့သည် ဈေးသက်သာပြီး ခန့်မှန်းနိုင်သော Testosterone ပမာဏကို ထုတ်ပေးသည် — သို့သော် ကိုယ်တိုင်ထိုးရန် ခက်ခဲပြီး မကြာခဏ မသက်မသာမှုနှင့် ဆက်စပ်နေသည်။ မကြာသေးမီက အရေပြားအောက် (SC) နည်းသည် ရေပန်းစားလာသည် အကြောင်းမှာ ကိုယ်တိုင်ထိုးရန် များစွာ ပိုလွယ်ကူသောကြောင့်ဖြစ်ပြီး ရရှိနိုင်သော အထောက်အထားများကလည်း ၎င်း၏ လက်တွေ့ဖြစ်နိုင်မှုကို ထောက်ခံသည်။

SC နည်း၏ အဓိက အားသာချက်များ ပါဝင်သည်မှာ —

• ကိုယ်တိုင်ထိုးရန် ပိုလွယ်ကူ： ကြွက်သားနက်နက်သို့ ထိုးရန် သို့မဟုတ် အကူအညီတောင်းရန် မလိုအပ်ပါ။
• Less pain: Smaller needles and a shallower injection make it considerably more comfortable for most men.
• Sciatic အာရုံကြော ထိခိုက်မှု အန္တရာယ် မရှိ： တင်ပါး IM ထိုးဆေး၏ သိရှိထားသော (ရှားပါးသော်လည်း) အန္တရာယ်တစ်ခုဖြစ်သည်။
• တည်ငြိမ်သော ဟော်မုန်း ပမာဏ： SC ထိုးဆေးသည် အမြင့်ဆုံးနှင့် အနိမ့်ဆုံး အတက်အကျ နည်းပြီး ပိုချောမွေ့၍ ပိုတည်ငြိမ်သော Testosterone ပမាဏကို ထုတ်ပေးသည်။
• ကုသမှု ဆက်လက်လိုက်နာမှု ပိုကောင်း： အဆင်ပြေပြီး သက်တောင့်သက်သာရှိသောကြောင့် လူနာများသည် ရေရှည်တွင် ကုသမှုကို ဆက်လက်ခံယူရန် ပိုဖြစ်နိုင်သည်။

A landmark 52-week clinical trial published in The Journal of Urology found that a weekly subcutaneous testosterone enanthate auto-injector produced steady testosterone levels with small fluctuations, and that more than 95% of patients reported no injection-related pain (Kaminetsky et al., J Urol 2019). Worth knowing what that figure describes: the trial used a licensed auto-injector device delivering a fixed dose, not a vial and a hand-held syringe. The comfort of the shallow route carries over; the exact percentage belongs to the device.

IM vs SC: What Is the Difference?

Feature	Intramuscular (IM)	Subcutaneous (SC)
Injection depth	Deep into the muscle	Into the fat layer under the skin
Common site	Buttock or outer thigh	Abdomen (belly) or thigh
Needle size	Longer, larger gauge	Shorter, smaller gauge (23-25G)
Pain level	Moderate discomfort	Usually mild
Self-administration	Difficult; may need help	Easy to do alone once taught
Testosterone levels	Larger peaks and troughs	Smoother, more stable

Things You Need to Prepare

• Alcohol swabs
• Your prescribed testosterone vial (e.g., testosterone enanthate or cypionate) — always check the expiry date
• A 1 mL Luer-Lok syringe (preferred to prevent the needle from disengaging due to the oil’s viscosity)
• A drawing-up needle (18-21G) to draw the testosterone from the vial
• A fine short injection needle (23-25 gauge, 5/8-inch) for the subcutaneous injection
• A sharps disposal container — a rigid, puncture-proof container kept for needles only, never the household bin

Where to Inject: The Landmark

The two recommended sites for subcutaneous testosterone injection are:

• The abdomen (belly): Inject into the fatty tissue 3 to 5 cm to the side of the belly button (umbilicus). Avoid the area too close to the navel.
• The thigh: The fatty tissue of the front or outer thigh is also a suitable site.

Gently pinch a fold of skin and fat to lift it away from the muscle. This helps ensure the injection goes into the subcutaneous layer and not the muscle. Move the spot every week — injecting repeatedly into the same patch of fat leaves firm lumps that absorb the oil unpredictably, so the dose stops behaving the way your blood tests suggest it should.

Step-by-Step: How to Do a Subcutaneous Testosterone Injection

⚠️ Important: Do not attempt your first injection by yourself. You must be taught and supervised by a health professional until you are fully competent. Reading a sequence of steps is not the same as having done it once with someone watching, and the steps below are a reminder for men who have already been trained — not a substitute for that training.

1. Wash your hands thoroughly and sit in a comfortable chair with your supplies ready.
2. Decide on your injection site (abdomen 3-5 cm beside the navel, or thigh). Alternate sites with each injection.
3. Draw the prescribed testosterone dose from the vial using the larger drawing-up needle (18-21G) on your Luer-Lok syringe.
4. Remove all air bubbles from the syringe (air must not be injected).
5. Replace the drawing-up needle with the fine injection needle (23-25G).
6. Clean the injection site with an alcohol swab and let it air-dry.
7. Gently pinch a fold of skin and insert the needle at a 45 to 90-degree angle into the fatty tissue.
8. Slowly inject the testosterone over several seconds.
9. Remove the needle and gently press the site with a clean cotton ball or gauze. Do not rub.
10. Dispose of the needle and syringe safely in your sharps container.
11. Never reuse a needle or syringe, and never share them with another person — including a relative or friend on the same treatment. A reused needle is blunt and hurts; a shared one transmits blood-borne infection.

One important exception. The ultralong-acting ester testosterone undecanoate is not a formulation for self-injection at home. It is a large-volume oily preparation, given slowly in a medical setting, after which the patient is observed for a period — because it carries a small but recognised risk of pulmonary oil microembolism and of an anaphylactic reaction, which announce themselves as a sudden cough, tightness in the chest, breathlessness or dizziness during or just after the injection. If you are on testosterone undecanoate, your injections belong in a clinic rather than at your kitchen table.

Dose — and Why It Is Not Yours to Adjust

In the 52-week auto-injector trial, the starting dose was 75 mg once weekly, moved down to 50 mg or up to 100 mg according to blood levels. Those figures appear here because patients reasonably ask what is typical — not as a schedule to follow. Your own dose is set by your doctor from your symptoms and your blood results, and on-treatment testosterone is measured midway between injections.

The number that most often forces a change is not testosterone at all. It is the haematocrit — the proportion of your blood made up of red cells. Testosterone raises it, and if it climbs too far the blood becomes thicker, which matters for clotting risk. That is managed by lowering the dose, spacing the injections differently or, in some cases, donating blood — none of which anyone can judge without the test. Blood pressure and PSA are followed for the same reason. Taking more than you were prescribed does not produce a better result; it produces a higher haematocrit.

Possible Side Effects

Local reactions are usually mild and temporary, and may include:

• Minor redness, itching, or a small painless lump at the injection site
• Light bruising or bleeding
• Firm thickened patches of fat if the same spot is used repeatedly — the reason for rotating sites

Because testosterone levels achieved via SC are similar to IM, the general systemic effects of testosterone therapy still apply and require monitoring — a rise in red blood cell count (haematocrit), blood pressure and PSA, suppression of the body’s own production, worsening of untreated sleep apnoea, and breast tenderness or enlargement. This is why regular follow-up with your urologist is essential. Changing the route does not change any of it.

What Is Not Normal — and What Cannot Wait

Most injection-site reactions settle within a day or two. These do not, and should be looked at rather than waited out:

• Spreading redness, increasing swelling, warmth or any discharge at the injection site — particularly with fever or chills. That is an infection, and it needs to be seen the same day rather than at the next appointment.
• Pain that is worse on day three than it was on day one, or a lump that keeps growing.

Separately, testosterone therapy itself has a short list of symptoms that are not for the next appointment either. Chest pain, sudden breathlessness, pain or swelling in one calf, or a sudden severe headache with weakness or difficulty speaking are emergencies — go to hospital and tell the team you are on testosterone. The same applies to a cough, chest tightness or dizziness during or just after an injection of testosterone undecanoate.

What Injections Do to Fertility

This is the part most often missing from an article about technique. Testosterone given from outside switches off the signal from the brain that drives the testicles, and sperm production falls with it. In many men on weekly injections the sperm count drops to zero. Testosterone is not a fertility treatment — for as long as you are on it, it does the opposite.

It is usually reversible after stopping, but recovery is measured in months rather than weeks and is not guaranteed in every man. If children are a possibility — now or in a few years — say so before you start, because there are ways of raising testosterone that do not suppress sperm production, and because azoospermia discovered later is very often the treatment itself rather than a separate problem. This is set out in more detail on the male fertility and microsurgery service page.

The route of administration is largely a matter of preference; the monitoring schedule is not optional. See what structured long-term follow-up looks like under our testosterone therapy service.
