IVF has brought the fertilization of spermatozoa ad oocyte into the lab in alternative to female's fallopian tube. It absorbs generation of ovulation to get multiple oocytes, making more embryos accessible to achieve higher pregnancy rates. Regular supervision of ovarian follicular enhancement and plasma estradiol level determination by ultrasonography would specify the reaction to ovarian stimulus. At the definite follicular growth, the oocytes are supposed to be obtained by the follicles. These oocytes are then blended with apt number of spermatozoa from the donor and are contained in an incubator to fertilize which are experiential microscopically after a gap of 16-18 hours. Once oocyte aspirates, embryos are transported to the uterine cavity within 2-6 days. If implantation results, pregnancy confirms by 14-16 days after the transplantation of embryo by determining the occurrence of HCG in urine or blood sample.
Common indications of infertility include:
Absence or blockage of fallopian tubes: Fertilization of egg takes place while passing through fallopian tube, therefore this process cannot take place of the tube is absent or blocked.
Endometriosis: It happens when the womb lining covers other pelvic structure such as ovaries, peritoneum, ligaments, bladder and bowel. It may cause inflammation and irritation leading to scarring. It may also lead to infertility, though the reason for the same cannot be defined.
Irregular ovulation: Pituitary gland exudes hormones for the ovaries after getting signals from a part of our brain. During the monthly menstrual cycle ovaries ripe egg due to these hormones. Ovulation may be absent or irregular if the menstrual cycle does not take place or is absent.
Low motility: If the sperm released in the semen during sexual intercourse are less or are not mortile to enter female reproductive system, it is impossible to conceive in this case.
Unexplained In fertility: In many cases the cause of infertility cannot be defined even after every possible investigation and medication.
Infertility treatment Steps:
Stimulating ovaries: A hormone named FSH is injected in a series to stimulate ovaries for the production of more than an egg per cycle.
Preventing pre-mature ovulation: it is achieved by discarding communication between brain and ovaries to obtain control of ovulation day in order to restrict the release of egg before it can be collected.
Trigger ovulation: Injection is prescribed to trigger up the process of ovulation.
Collection: Fertilization starts after collecting eggs and sperm.
Culturing: The matured eggs are picked and kept with sperm for transfer on later stage if required.
Transfer: The embryos are injected into the uterus through cervix. Age of a woman, cause of infertility and sperm quality contributes to the success of infertility treatment.
