Antagonist ovulation regimens typically take about 12 days, and the exact time actually depends on the individual’s sensitivity to the drug as well.
An antagonist regimen is also an ovulation regimen that uses a gonadotropin-releasing hormone analog (GnRH) antagonist to inhibit premature luteinizing hormone production. The antagonist regimen can be used in patients with relatively poor ovarian function, advanced age, polycystic ovary syndrome, and poor ovarian response.
The number of days of ovulation induction depends on the follicular development, and generally the antagonist regimen requires about 12 days of ovulation induction.
The antagonist regimen starts with GnRH antagonist when the follicle grows to a diameter of 12 mm or more after passing the test on day 3 of the menstrual period, and chorionic gonadotropin is given until the follicle is larger than 18 mm in diameter, and the follicle’s growth needs to be monitored regularly during the ovulation treatment.
Women who need ovulation induction therapy should go to a regular hospital and be evaluated by a doctor. The use of the above medications should be in accordance with medical advice.
