Decoding the In Vitro Fertilization (IVF) Procedure

 Decoding the In Vitro Fertilization (IVF) Procedure


VF involves many steps: -

·       Ovarian Stimulation

·       Egg Retrieval

·       Sperm Retrieval Fertilization and

·       Embryo Transfer.

One cycle of IVF will take concerning 2 to a few weeks. over one cycle is also required.

Ovulation induction

The start of an IVF cycle begins by mistreatment artificial hormones to stimulate the ovaries to supply multiple eggs — instead of the only egg that usually develops monthly. Multiple eggs are required as a result of some eggs won’t fertilize or develop unremarkably when fertilization.

Several totally different medications are also used for: -

·       Ovarian stimulation

·       Oocyte maturation

·       To prevent premature biological process

·       To prepare the liner of your womb

To determine once the eggs are prepared for assortment either a vaginal ultrasound or Blood tests to live your response to female internal reproductive organ stimulation medications are done.

Sometimes IVF cycles ought to be cancelled before egg retrieval for one in all these reasons:

·       Inadequate range of follicles developing

·       Premature biological process

·       Too several follicles developing, making a risk of female internal reproductive organ hyperstimulation syndrome

·       Other medical problems

If your cycle is cancelled, your doctor may advocate dynamic medications or their doses to market a more robust response throughout future IVF cycles. otherwise, you are also suggested that you just want an egg donor.

Egg retrieval:

Egg retrieval may be worn out your doctor’s workplace or a clinic thirty-four to thirty-six hours when the ultimate injection and before ovulation.

·       During egg retrieval, you’ll be insensible and given pain medication.

·       Transvaginal ultrasound aspiration is that the usual retrieval technique. An ultrasound probe is inserted into your canal to spot follicles. Then a skinny needle is inserted into an ultrasound guide to travel through the canal and into the follicles to retrieve the eggs.

·       If your ovaries aren’t accessible through transvaginal ultrasound, an abdominal ultrasound is also accustomed guide the needle.

·       The eggs are far from the follicles through a needle connected to a suction device. Multiple eggs may be removed in concerning twenty minutes.

·       After egg retrieval, you'll expertise cramping and feelings of fullness or pressure.

·       Mature eggs are placed in a nourishing liquid (culture medium) and incubated. Eggs that seem healthy and mature are mixed with spermatozoa to try to make embryos. However, not all eggs are also with success impregnated.

Sperm retrieval

If you’re using your partner’s spermatozoa, a ejaculate sample has to be provided at your doctor’s workplace or clinic the morning of egg retrieval. Typically, the ejaculate sample is collected through masturbation. Different strategies, like male reproductive gland aspiration — the employment of a needle or operation to extract spermatozoa directly from the testicle — are generally needed. Donor spermatozoa can also be used. Spermatozoa are separated from the ejaculate fluid within the research laboratory.


Fertilization may be tried mistreatment 2 common methods:

·       Conventional insemination. throughout typical insemination, healthy spermatozoa and mature eggs are mixed and incubated long.

·       Intracytoplasmic spermatozoa injection (ICSI). In ICSI, one healthy spermatozoa is injected directly into every mature egg. ICSI is usually used once ejaculate quality or range could be a drawback or if fertilization makes an attempt throughout previous IVF cycles unsuccessful.

In bound things, your doctor could advocate different procedures before embryo transfer: -

Assisted hatching. Concerning 5 to 6 days when fertilization, an embryo “hatches” from its encompassing membrane (zona pellucida), permitting it to implant into the liner of the womb. If you’re an older woman, or if you have got had multiple unsuccessful IVF makes an attempt, your doctor may advocate aided hatching — a method within which a hole is formed within the zone simply before transfer to assist the embryo hatch and implant. Aided hatching is additionally helpful for eggs or embryos that are antecedent frozen because the method will harden the zone.

Preimplantation genetic testing. Embryos are allowed to develop within the setup till they reach a stage wherever a tiny low sample may be removed and tested for specific genetic diseases or the proper range of chromosomes, usually when 5 to 6 days of development. Embryos that don’t contain affected genes or chromosomes may be transferred to your womb. Whereas preimplantation genetic testing will scale back the chance that a parent can depart this world a genetic drawback, it can’t eliminate the danger. antenatal testing should be suggested.

Embryo transfer

·       Embryo transfer is completed at your doctor’s workplace or a clinic and typically takes place 2 to 5 days when egg retrieval.

·       You might incline a gentle sedative. The procedure is sometimes painless, though you may expertise delicate cramping.

·       The doctor can insert an extended, thin, versatile tube known as a tube into your canal, through your cervix and into your womb.

·       A syringe containing one or a lot of embryos suspended in an exceedingly bit of fluid is connected to the top of the tube.

·       Using the syringe, the doctor places the embryo or embryos into your womb.

·       If positive, an embryo can implant within the lining of your womb concerning

·       six to ten days when egg retrieval.
