There are many factors that affect pregnancy. Low estrogen has the potential to affect ovarian function, which produces follicles, and abnormal ovarian function affects follicle maturation and normal ovulation. Without mature follicles ovulating, the egg and sperm cannot meet and combine to form a fertilized egg, and the fertilized egg cannot continue to develop into a fetus if it cannot settle in the uterine cavity. Therefore, low estrogen may cause infertility. Low estrogen is also noted to exclude the effects of some diseases, such as diabetes, ovarian diseases, ovarian tumors and so on. Low estrogen may be related to personal bad habits, such as often stay up late, do not eat on time, often drink coffee and other stimulating beverages, blind pursuit of weight loss. Normally, you can eat more soy products and moderate consumption of goji berries to help improve.
