The first prerequisite for pregnancy is ovulation after the follicles have matured, and the egg and sperm will be fertilized in the fallopian tube and reach the uterine cavity, where the embryo will be laid, and then the fetus will be conceived. Therefore, if there is no follicle, pregnancy is not possible. Nowadays, due to many diseases, such as polycystic ovary syndrome and acquired amenorrhea, women may have immature follicles and fail to ovulate, in which case ovulation treatment can be performed to promote the maturation of eggs. However, in this case, it may promote the maturation of more than one egg, some may be 2-3. If you see the follicles mature and then conceive, it is easy to conceive multiples, and if there are more than triplets, then you may have to undergo fetal reduction treatment if necessary.
