The main effects of this drug are to inhibit the rate of development of the dominant follicle, control the timing of ovulation and prevent early ovulation by the ovaries in order to facilitate the collection of more mature eggs for artificial insemination, mainly for use in assisted reproductive technology procedures. It is mainly used clinically in combination with human menopausal gonadotropin or recombinant human follicle stimulating hormone to prevent early LH peaks and synchronize the timing of ovulation with endometrial development, and also serves to enable more follicles to develop and mature, enabling the extraction of more mature follicles and improving the success rate of artificial insemination. Some adverse reactions can also occur after this drug is injected. It is important to follow your doctor’s instructions when using the medication.
