Pregnancy is the most wonderful experience one can have, but what happens if you are unable to have a successful pregnancy due to problems fertility or other complications? Pregnancy complications such as breech fetuses and implantation failure are just a few of the many things that can go wrong. According to gynecologist and obstetrician Horace M Fletcher, “failed pregnancies are nature's way of caring for what might otherwise have been an abnormal pregnancy; the egg is fertilized, but sometimes the fetus is abnormal and sometimes there is an infection or low hormone levels.” Preimplantation can improve implantation success during embryonic development, allowing them to revitalize and develop consistently without complications.

IVF is a fertilization of oocytes (ovarian cell which becomes an egg) carried out in a Petri dish. During IVF, embryos develop and are then transferred to the blastocyst stage into the uterus. The embryo is kept in the laboratory for between 2 and 6 days, which allows it to develop into an organism composed of various cells on which it will then be implanted in the mother's uterus. The blastocyst stage is the period in which the embryo undergoes a series of five or six mitotic cell divisions with an invariable volume called cleavage. Initially, at this stage, the embryo is ready to be implanted into the endometrium (inner lining of the uterus). However, the advice to transfer the embryo at the blastocyst stage will be decided by your doctor and embryologist based on your specific case for a higher probability of successful pregnancy. Additionally, to ensure the effectiveness of the IVF procedure, preimplantation testing to detect genetic abnormalities can be carried out. Preimplantation genetic diagnosis (PGD) is a procedure used before implantation to help identify genetic abnormalities within the embryo and is used to prevent the transmission of certain diseases or genetic disorders to the child. Rather, the natural process of pregnancy without preimplantation begins with implantation and conception. Women release a group of eggs from the ovaries created into follicles (fluid-filled sacs) once a month. Ovulation occurs when the follicle expels an egg; ideally two weeks before a woman's next menstrual cycle. Fertilization, on the other hand, occurs two weeks after a woman's last period, when the sperm and egg merge in one of the fallopian tubes. During fertilization, if a Y sperm fertilizes the egg, the embryo will develop into a boy; while an X sperm fertilizes the egg to become a girl. The first trimester lasts up to 12 weeks during which the mother undergoes a vast series of hormonal changes and the embryo begins to develop into a fetus. Levels of the hormone human chorionic gonadotropin (hCG) increase during pregnancy, forcing the menstrual cycle to stop. Other hormonal changes mothers experience during the first trimester include, but are not limited to: breast tenderness and frequent urination. The fetus is located in the amniotic sac – a sac made up of membranes: the amnion and the chorion which secrete the.
