Sexual drive
Testosterone is the hormone behind desire. Libido and sexual interest are usually the first things to lift, often within weeks.
Doctor-tested, doctor-balanced testosterone. Testosterone replacement therapy (TRT) brings a low testosterone level back into a healthy range, to support your drive, energy, mood and strength. It starts with a full blood panel, and your doctor rechecks your levels every 8 to 12 weeks.
Testosterone is the main male hormone. It drives libido, supports erections, muscle, bone, mood and focus. From the mid 30s it falls slowly, and stress, poor sleep and extra weight can push it lower. Testosterone replacement therapy, or TRT, sometimes called hormone replacement therapy for men, gives back what your body is missing, with a doctor-prescribed injection or cream, so your level sits in a healthy range again.
It is only started after blood tests confirm a low level. At SuamiSihat Clinic a licensed men's health doctor reads your results, builds a plan around your lifestyle and rechecks your blood regularly, so the dose stays safe and right for you.
In half a minute, one of our men's health doctors explains how testosterone replacement therapy works at SuamiSihat Clinic, from the first blood test to the follow-up checks.

When a low level is brought back into range, these are the areas men most often notice. Results depend on your starting level and your lifestyle.
Testosterone is the hormone behind desire. Libido and sexual interest are usually the first things to lift, often within weeks.
Men with low levels often feel flat and run down. A healthy level can help, especially together with better sleep and training.
It helps the body build lean muscle and burn belly fat, so your training finally shows. Changes build over months.
Low testosterone can bring irritability and low mood. Studies show mood improves slightly when levels are restored.
Four steps, always in this order. The blood test comes first, and the follow-up checks never stop.
Testosterone travels in the blood and tells muscle, bone, brain and sexual tissue to stay strong and responsive.
A morning blood test shows your real level, plus estradiol, PSA, liver function and blood count, so treatment is never a guess.
An injection or cream tops up what is missing, bringing your level up into the healthy range and keeping it there.
Repeat blood tests every 8 to 12 weeks guide small dose changes, so the benefits stay and the risks stay low.
Your doctor recommends the option that fits your blood results, your routine and how often you can visit.
A doctor-given injection into the muscle that releases testosterone slowly over weeks, so there is nothing to remember day to day.
A measured amount applied to the skin each morning at home, for steady day-to-day levels and easy dose changes.
For men whose estradiol rises on treatment, the cream is paired with support that keeps testosterone and estrogen in balance.
Your doctor confirms suitability after your blood tests. These are the general guidelines.

Testosterone, estradiol, PSA, liver function, blood count and other markers are measured before anything starts. Come in the morning, skip alcohol and smoking for 24 to 48 hours, avoid saunas or hot baths for 48 hours, and tell us about any medicines or supplements.
Your doctor explains your results in plain words and recommends a long-acting injection, a daily cream or cream with estrogen balance support, based on your hormone profile and routine.
The injection is given by our team at the clinic. The cream is applied at home each morning, and we show you exactly how much and where.
Repeat blood tests and doctor reviews every 8 to 12 weeks at first, then less often once you are stable. The dose is adjusted for the best effect with the lowest risk.
Testosterone works on different parts of the body at different speeds. This is the usual order, based on clinical research.
Libido and sexual interest are often the first to lift, and mood starts to feel steadier.
Erections can improve, and many men feel more motivated and less run down.
Body shape changes: less belly fat and more lean muscle, especially with training.
Strength and bone density keep building towards their full benefit.
Timing varies between individuals and depends on your starting level (Saad et al., 2011).
Hormones are one piece. These work on the other pieces of energy, performance and fertility.

Ask on WhatsAppTestosterone replacement therapy, or TRT, is a doctor-led treatment that brings a low testosterone level back into a healthy range, using a long-acting injection or a daily cream. It is only started after blood tests confirm the level is low, and it is monitored with regular blood tests.
Common signs are low sex drive, weaker erections, tiredness, low motivation, poor focus, irritability, loss of muscle and more belly fat. These signs have other causes too, so a blood test is the only way to know.
With a morning blood test, when testosterone is naturally highest, usually repeated to confirm. We also check estradiol, PSA, liver function and blood count so your doctor sees the full picture.
Come in the morning. Avoid alcohol and smoking for 24 to 48 hours and saunas or hot baths for 48 hours before the test, and tell the doctor about any medicines or supplements you take. Your doctor will tell you if anything else is needed.
Yes, when it is prescribed and monitored by a doctor. A large 2023 trial found no rise in major heart events. Most problems happen when men self-medicate without testing. We screen you first, then recheck your blood count, PSA and liver every 8 to 12 weeks and adjust the dose.
It can. Testosterone treatment lowers your own sperm production. If you plan to have children soon, tell your doctor first. A semen analysis and fertility-friendly options can be discussed before you start.
Both work well. The long-acting injection is given at the clinic every few months, so there is nothing to remember. The cream is applied daily at home and allows small dose changes. Your doctor helps you choose based on your blood results and routine.
Libido and mood often improve within 3 to 6 weeks. Erections and energy can take up to 3 months, body shape 3 to 6 months, and strength and bone 6 to 12 months.
Not always. It depends on the cause. Some men improve their levels with better sleep, weight loss and less stress, and stop under medical guidance. Your doctor reviews with you whether to continue.
Men over 30 should test at least once a year, or sooner if they feel tired, irritable or less interested in sex. On TRT, levels are checked every 8 to 12 weeks at first, then less often once stable.
