The group that received combination treatment of Nigella sativa and lead acetate also showed a decrease in the size of Graafian follicle a decrease in the number of primary secondary and Graafian follicles as well as normal structure of the Graafian follicle.In contrast to our observations Yadav and Agarwal (2011) reported that the ovarian follicles showed degenerative changes following administration of aqueous extract of Nigella sativa.
While the Graafian follicle is indeed the dominant follicle that releases the egg, after releasing the egg, the Graafian follicle does not migrate and attach to the uterine wall, as stated in the article, rather it turns into the corpus luteum, and is part of the ovary.
Primary ovarian pregnancy, a rarely seen form of ectopic pregnancies (0.5-1%), occurs due to inability to release fully mature ovum outside the ovary and entrance of spermatozoa into the Graafian follicle.1 The incidence of primary ovarian pregnancy is reported to be 1 in 7000 to 40000 pregnancies.2

A recent study demonstrated that the expression levels of GDF9 and BMP15 proteins decreased in the early stages of folliculogenesis (primordial, primary and secondary follicles) and then reached the highest levels in the late stages of folliculogenesis (graafian follicles) in unstimulated ovarian tissues from PCOS patients (15).
