Ovulation Process:
The pituitary gland, located in your brain, releases a hormone once every month. This hormone instructs the ovaries to create many follicles, which are fluid-filled cysts. The hormone oestrogen is secreted by the growing follicles. In order to prepare for pregnancy, oestrogen causes the uterine membrane to thicken.
The follicles cease developing on day seven of your cycle, with the exception of one. This follicle keeps expanding and nourishes an oocyte (egg) that is developing within.
On day 12, a surge of oestrogen is released into the bloodstream by the developing follicle. Your blood carries the oestrogen along. The pituitary gland in your brain releases luteinizing hormone in response to the oestrogen reaching it. This hormone causes a quick growth spike in the follicle.
The egg within the follicle separates from the follicle just before ovulation. The neighboring fallopian tube begins to migrate toward and around the follicle as the follicle begins to produce chemicals.
The egg and fluid are ejected into the abdominal cavity when the follicle expands to the point of breaking open.
Fimbriae, or tiny finger-like projections at the termination of the fallopian tube, move over the ruptured follicle and seize the egg.
The egg is moved to the fallopian tube's opening. Muscle contractions push the egg gently towards the direction of the uterus once it has entered the fallopian tube's walls.
Either sperm will contact the egg as it travels down the fallopian tube, resulting in fertilization, or the egg will arrive in the uterus unfertilized and be reabsorbed into the body.
Conception Process:
A woman must fertilize her egg within the 12 to 24 hours following ovulation if she wants to get pregnant.
The surge of oestrogen right before ovulation also creates the protein-rich transparent jelly that covers the vagina during intercourse within the neck of the uterus (the cervix). Thus, the vagina became acidic (which prevents thrush and other infections). Sperm can survive in this environment as well. Rapidly moving sperm swim up and into the cervix, where they can live for up to five days in the mucus until an egg is produced.
The fallopian tube might grab the egg because it is wrapped in sticky cells when it is released after ovulation. The sperm begin to break down the adhesive cells when they encounter the egg in the fallopian tube. While only one sperm is required to create a baby, numerous are required to cling to the egg's membrane and outer shell before one may penetrate and fertilize it.
After fertilization, substances are produced to prevent the entry of more sperm before the egg and sperm swiftly combine and split to form an embryo.
The fertilized egg continues to divide and move toward the uterus throughout the course of the following four to five days.
The burst follicle (now known as the corpus luteum), which releases the hormone progesterone into your bloodstream, primes the uterus for the egg to implant.
The pregnancy is sending an increasingly potent signal to the ovary to prolong and boost the production of progesterone, which the pregnancy needs to live, while it develops and installs itself into the mother's uterine lining and blood vessels.
