Ovulation induction can usually start after 2 to 4 weeks after the down-regulation injection, and the exact time needs to be decided according to the woman’s physical condition and follicle growth and development.
After the injection, the follicles will gradually grow and develop to maturity. After 2 to 4 weeks, the follicles will have grown to about 18-20mm, and then ovulation can be promoted. If the woman’s health is good or the follicles grow and develop quickly, the ovulation induction time is relatively short; if the woman’s health is poor or the follicles grow and develop slowly, the ovulation induction time is relatively long.
It should be noted that after the injection, the hormones may fluctuate and can usually recover on their own.
If there are uncomfortable symptoms after taking down-regulation injections, it is recommended to go to the hospital as soon as possible, and the doctor will regulate the treatment to avoid delaying the condition.
