Your doctor has given the right modality of treatment.. Follicular study helps you to know the size and no of developing follicle. When the size of the follicle reaches approximately 20*20mm, hcg inj is given. Within 36 hrs, follicle will rupture. This is the time when sperms are necessary in the female genital tract.. Sperms can survive upto 72 hrs in the female genital tract but ovum will survive only for 24 hrs.. So timed intercourse should be in and around the time of ovulation. To know whether you r preg get a preg test by 31st day or an hcg blood test to detect preg earlier. Hope i have answered your queries. Good day. </s>
