If the embryo is compared to a “seed”, the endometrium can be compared to the “soil”. The survival of a seed depends on the fertility of the soil, and the success of embryo implantation is also closely related to the endometrium. In many women, the endometrium is damaged by abortion and diagnostic curettage, resulting in a thin endometrium, which prevents the embryo from implanting and causes infertility. Endometrial thinning has become a cause of distress for many infertile women and a very difficult problem for doctors. High doses of estrogen, aspirin, vitamin E, etc. are commonly used to treat thin endometrium, and long-term use of these drugs can have adverse effects on the body.

Both estradiol and vitamin E can stimulate endometrial proliferation. Therefore, snow clam oil is used for patients with thin endometrium to supplement the level of estrogen and promote endometrial proliferation, which can effectively increase the thickness of endometrium and facilitate embryo implantation.
