Hormone therapy
A progestogen course can bring on a bleed and protect the womb lining. Cyclic hormones or the pill can give you a regular cycle again.
Hormonal causes
No period? Let's find out why
Amenorrhea Treatment in Gangnam, Seoul, that finds the cause first
Amenorrhea means your periods have stopped or never started. At Sinsoe Women's Clinic in Gangnam, Seoul, a female OB-GYN looks for the reason with a pregnancy test, hormone blood tests and a pelvic ultrasound, often in one visit. Treatment then depends on the cause, from hormone therapy to managing PCOS or a thyroid problem. An English-speaking coordinator helps you from your first message to your results.

The basics
What is amenorrhea?
Amenorrhea is the medical word for missing periods. Doctors call it secondary amenorrhea when periods stop for 3 months or more in a woman who used to have regular cycles, or for 6 months if her cycles were irregular. Primary amenorrhea means periods have not started by about age 15.
The most common cause is pregnancy, so that is always checked first. After that, the usual causes are hormonal: stress, weight change or hard training can switch off ovulation, and so can PCOS, thyroid disease or a high prolactin level.
Missing periods are a sign, not a disease. Treatment works on the cause, and many women get their cycle back once the cause is found.
Common causes Why periods can stop
- Pregnancy or breastfeeding
- Stress, weight loss or intense exercise
- Polycystic ovary syndrome (PCOS)
- Thyroid problems or high prolactin
- Early menopause or low ovarian reserve
- Scar tissue inside the uterus after a procedure
Not always amenorrhea
- A late or skipped period once in a while is common, especially after travel or illness
- Cycles that are irregular but still come are covered on menstrual regulation

Missing period patterns and what they can mean
Your story helps your doctor narrow down the cause before any test. Here are common patterns we see.
| Your pattern | What it can point to |
|---|---|
| Period late, recent unprotected sex | Pregnancy first. A urine or blood hCG test gives a clear answer. |
| Stopped after stress, dieting or heavy training | Hypothalamic amenorrhea, where the brain pauses the signals to the ovaries. |
| Long gaps for years, acne or extra hair | Possible PCOS, the most common hormonal cause in young women. |
| Hot flushes, night sweats, under 40 | Early menopause (premature ovarian insufficiency). Hormone tests and AMH help check. |
| Stopped after a D&C or miscarriage care | Scar tissue inside the uterus, which can be looked at with hysteroscopy. |
| Milky discharge from the nipples | A high prolactin level, which a blood test can confirm. |
This table is a guide only. Your doctor will confirm the cause with tests.
Message us the same day if you have:
- A positive pregnancy test with pain or bleeding
- Severe headaches or changes in your vision
- Very low weight, dizziness or fainting
If it is an emergency, go to the nearest hospital emergency room.
Treatment
How amenorrhea is treated
There is no single treatment for missing periods. Your doctor chooses one based on the cause and on whether you want to get pregnant soon.
Treating the underlying cause
Thyroid or prolactin medicine, a PCOS plan, or support with weight, stress and training. See hormonal imbalance therapy.
Thyroid, PCOS, stressA procedure, if needed
If scar tissue or a structural problem blocks the uterus, a short procedure such as hysteroscopy may be suggested.

What is a progesterone challenge?
You take progestogen tablets for several days. If you have a bleed within about a week after stopping, your ovaries are making estrogen and the uterus and outflow are working. If no bleed comes, your doctor looks for other causes.
It is simple, done at home, and helps decide the right treatment.

Quick answers
Missing periods: common questions
Where can I get amenorrhea treatment in Gangnam with an English-speaking doctor?
Sinsoe Women's Clinic is at 537 Nonhyeon-ro, Gangnam-gu, Seoul, a 4-minute walk from Eonju Station Exit 7 (Line 9). All doctors are female, and an English-speaking coordinator helps you from booking to results. Message us on WhatsApp at +82-10-9517-5719.
How long without a period is too long?
If you used to have regular periods and have had none for 3 months, see a doctor. If you are not pregnant and have no period for 6 months with irregular cycles, also get checked.
I'm not pregnant. Why has my period stopped?
Stress, weight change, hard exercise, PCOS, thyroid problems and high prolactin are common reasons. Tests help find which one applies to you.
How much does a missed period check cost in Seoul?
From the clinic's published fee schedule (June 2026): urine pregnancy test ₩10,000, blood β-hCG ₩30,000, gynecologic ultrasound ₩100,000, TSH ₩25,000 and AMH ₩80,000. Confirm before your visit, and ask the coordinator for an estimate for your tests.
Can missing periods affect my fertility?
If you are not ovulating, it can be harder to get pregnant. Many causes are treatable. Tell your doctor if you plan to get pregnant so the plan fits that goal.
Is it dangerous not to have periods?
Missing periods themselves are not dangerous, but the cause can matter. Low estrogen can weaken bones, and long gaps without a bleed can thicken the womb lining.
Can I take something to bring my period back?
A short course of progestogen often starts a bleed, but it does not fix the cause. Your doctor checks first so treatment is safe for you.
Can tourists get tested without Korean insurance?
Yes. Visitors pay as self-pay patients. Bring your passport.
