Do you need to monitor ovulation? When will monitoring start?

Do you need to monitor ovulation?

1. Women with long menstrual cycles and even amenorrhea cannot calculate the ovulation period, there may be late ovulation time or even no ovulation, and the hospital needs to be treated to judge the ovulation situation through B ultrasound monitoring and whether further ovulation is needed to promote ovulation and fertility.

2. For patients with polycystic ovary syndrome, the development of follicles can be checked through ultrasound monitoring, whether there are mature follicles being recruited, and whether to assist fertility treatment in the next cycle.

3. For patients with poor ovarian reserve, whether there is ovulation can be monitored by B ultrasound, and if there is ovulation, guidance for intercourse and accurate conception.

4. For patients with habitual miscarriage, ultrasound B monitoring to give luteal support and fetal protection treatment in time after ovulation.

How is ovulation monitored?

For women with a menstrual cycle of 28-30 days, the dominant follicles begin to develop from the 6th to 8th day of the menstrual cycle, and the next monitoring time can be determined according to the size of the dominant follicles after the initial monitoring on the 10th day of the menstrual cycle, usually the time of B ultrasound monitoring in each cycle is 3-4 times, the specific time is:

Maximum follicle diameter

Dominant follicles are 10-12 mm in diameter and the interval between next monitoring is 3-4 days;

Dominant follicle diameter 13-15 mm, the next monitoring interval is 2-3 days;

When the dominant follicle diameter is more than 16 mm, the next monitoring interval is 1-2 days.

After the natural cycle basal body temperature rises, the ultrasound monitors the follicle for vanishing or collapsing, indicating that it has ovulate. Ovulation induction cycles, when the follicle diameter > 18-20 mm, indicates that the follicle has matured.
