How long is the IVF ovulation promotion needle?

Ovulation stimulation is usually administered for 8 to 12 days. However, ovulation stimulation drugs are only the most important part of the medication regimen. Depending on the ovulation stimulation regimen, other drugs may be required for down-regulation before the use of ovulation stimulation drugs, resulting in a prolonged period of medication. Some require 50 to 60 days, or even longer. Ovulation stimulation is usually performed according to B-mode ultrasound. When the follicle diameter reaches 2 cm or multiple follicles reach 17 to 18MM, the night needle for follicle maturation and ovulation should be injected, and then the eggs should be retrieved within 36 hours. The specific time of egg retrieval should be observed according to the doctor's advice.
