Timing Method

The timing method is a method that uses hormone tests and ultrasound examinations to predict the date of ovulation as accurately as possible, so that sexual intercourse can occur at a time when conception is likely to occur.
In addition to natural cycle timing guidance, fertility drugs may be used to nurture follicles as needed.

Timing Method Process

1. Accurately predict ovulation date by LH check or ultrasonography

From the graph of the past basal body temperature, the few days from the low temperature period to the rising period are estimated as ovulation days.
When the time of ovulation approaches, you will be asked to visit the hospital, and a transvaginal ultrasound will be used to measure the size of the follicles and check their growth.
In the case of a natural cycle, after the follicle diameter reaches about 12 mm, it grows at a rate of about 2 mm per day, and ovulation occurs when the follicle diameter reaches about 18 to 22 mm, so we follow up by predicting how many more days she will ovulate.

A test for LH (Luteinizing Hormone), a hormone secreted in large amounts before ovulation, may also be performed.
In addition, the properties of cervical mucus change during the ovulation period.
Outside of the ovulation period, cervical mucus blocks the entrance to the uterus to prevent bacteria and other contaminants from entering the uterus, but when ovulation approaches, it changes to a clear, well-stretched consistency to facilitate the acceptance of sperm.

2. Follow the advice of the doctor regarding timing

We will give you specific instructions on timing (sexual intercourse).
If necessary, an ultrasound will be performed at a later date to confirm whether or not the timing of ovulation was correct.
An increase in basal body temperature is also an important clue whether ovulation has occurred.
The luteinizing hormone test (E2,P), which evaluates luteal function, is performed on a designated day after ovulation is confirmed.
If there is ovulation and the timing is right, then all you have to do is wait for pregnancy.

3. Establishment of pregnancy

If a gestational sac is found in the uterus at 5 weeks of gestation, it is called a clinical pregnancy.
Pregnancy is confirmed when a heartbeat is detected at 6-7 weeks of pregnancy.

Cost of Timing Method

The cost of the timing method cannot be generalized, as the number of visits, tests, and medications prescribed vary from person to person.
If covered by insurance, the cost is about ¥2,000 to ¥3,000 per visit.
However, multiple monthly ultrasound examinations to predict the date of ovulation and prescriptions for fertility drugs to stimulate ovulation may not be covered by insurance and may cost ¥10,000 to ¥20,000.

Notes on Timing Method

The timing method is to nurture mature eggs with high fertilization potential, predict or set the date of ovulation, and provide guidance on when to have sexual intercourse.
However, even with the best ovarian stimulation techniques, ovulation generally occurs only once a month.
Therefore, if you are busy, intercourse itself may be difficult, and it is not a good idea to try to conceive using the timing method.

In such a case, it is considered better to try to conceive by freezing the husband's sperm in advance and performing artificial insemination at the time of ovulation.
At our clinic, sperm can be cryopreserved, so please contact us at any time if you have any of the above conditions.
The pregnancy rate per timing for non-fertile couples is about 20%, while for infertile couples it is about 5-8%.
