Black beans contain a certain amount of phytoestrogens, so it is said that eating black beans can promote follicle development. It is advisable to make black beans into soy milk to drink, which will also have a supportive effect on the growth and development of follicles. However, if the follicles are not developing well, a blood test should be done to see if the values of follicle stimulating hormone, estradiol and luteinizing hormone are normal. Depending on the results of the comprehensive analysis, medication may be given if necessary, for example, ovulation treatment. You can take oral ovulation pills for five days on the fifth day of your period and then monitor the development of follicles by ultrasound and have intercourse when the follicles are dominant. At the same time, intramuscular injection of chorionic gonadotropin can be given to encourage the follicles to rupture and expel the eggs.
