Unscramble the Blue Letters

IVF wkors by mimicking the brilliant design of sexual rurdoeocitpn. In order to understand IVF, we first need to take a look at the natural process of baby making. Believe it or not, it all starts in the brain. Roughly fifteen days before fertilization can happen, the anterior pituitary gland secretes follicle stimulating hormone, FSH, which ripens a handful of follicles of the ovary that then release estrogen. Each follicle contains one egg, and on average, only one follicle becomes fully mature. As it gwros and continues to rsealee estrogen, this hormone not only helps cronatdoie gortwh and preparation of the uterus, it also communicates to the brain how well the follicle is dnveoilpeg. When the estrogen level is high enough, the anterior pituitary releases a surge of lnteiiunizg hormone, LH, which trgrgies otuilvoan and causes the foclllie to rupture and release the egg.

Original Text

IVF works by mimicking the brilliant design of sexual reproduction. In order to understand IVF, we first need to take a look at the natural process of baby making. Believe it or not, it all starts in the brain. Roughly fifteen days before fertilization can happen, the anterior pituitary gland secretes follicle stimulating hormone, FSH, which ripens a handful of follicles of the ovary that then release estrogen. Each follicle contains one egg, and on average, only one follicle becomes fully mature. As it grows and continues to release estrogen, this hormone not only helps coordinate growth and preparation of the uterus, it also communicates to the brain how well the follicle is developing. When the estrogen level is high enough, the anterior pituitary releases a surge of luteinizing hormone, LH, which triggers ovulation and causes the follicle to rupture and release the egg.
