The so-called nail art is mainly used to apply nail polish to the nails, and nail polish contains various chemical components that may have an adverse effect on the growth and development of the embryo, so for women who are already pregnant, it is recommended to prohibit nail art to avoid fetal malformations. However, for women who are not pregnant, nail care does not usually directly affect conception. This is because nail care does not affect the ovarian secretion function of women, nor does it affect the discharge of eggs, nor does it affect the union of sperm and eggs, nor the fertilization of eggs, nor does it have any adverse effect on the patency of the fallopian tubes of women. However, for the purpose of eugenics, nail care should not be performed during pregnancy preparation and folic acid should be taken at the beginning of pregnancy preparation to prevent neurovascular malformations in the fetus.
