The relationship between pregnancy and an ovum is established because the fertilization and subsequent implantation of an ovum into the uterine wall are the biological triggers for pregnancy [1], [2], [3]. Furthermore, the release of an ovum during ovulation is a prerequisite for the fertilization event that leads to pregnancy [4], [5].

procedureThe menstrual cycle proceeds in five steps: (1) The pituitary gland produces FSH, which signals the ovaries to produce estrogen. (2) When estrogen reaches a specific level for a set duration, the pituitary gland produces LH. (3) LH triggers ovulation, causing the ovary to release an egg into the fallopian tube. (4) The ovary produces progesterone to prepare the uterus for pregnancy. (5) If conception does not occur, hormone levels drop, the menstrual lining stops developing, and the lining is shed as a menstrual period.
