When a blockage in the fallopian tubes prevents sperm from adhering to the egg normally, zygote intra fallopian transfer (ZIFT) is utilised as an infertility treatment. Egg cells are extracted from a woman’s ovaries and fertilised in vitro. Laparoscopy is used to insert the resultant zygote into the fallopian tube. The procedure is a variation on the GIFT (gamete intrafallopian transfer) procedure. The pregnancy and implantation rates in ZIFT cycles were 52.3 and 23.2 percent, respectively, which were greater than the 17.5 and 9.7 percent found in IVF cycles.
Suitable condition for ZIFT
A woman must have at least one healthy fallopian tube where the zygote can be implanted to be a good candidate for ZIFT. The full ZIFT procedure takes about four weeks, including the time when the patient must first undergo superovulation hormone treatment. With superovulation, the doctor uses fertility drugs like Clomid to encourage the ovaries to generate several mature eggs, or ova. Clomid raises the levels of the hormones follicle-stimulating hormone (FSH) and luteinizing hormone (LH), which are necessary for oocyte maturation. If Clomid alone is insufficient to accelerate oocyte maturation, the doctor can inject extra FSH and LH intravenously to enhance the oral Clomid medicine for a more aggressive hormone therapy.
Procedure
The average ZIFT cycle lasts between five and six weeks. To promote egg production in the ovaries, the female must first take the fertility drug clomiphene. The woman will be given an injection containing human chorionic gonadotropins once the ovarian follicles have matured, as determined by the doctor (HCG or hCG). Approximately 36 hours later, the eggs will be collected, usually via transvaginal ovum retrieval. The resulting early embryos or zygotes are put into the woman’s fallopian tubes using a laparoscope after fertilisation in the lab.
ZIFT is an assisted reproductive procedure that can be used to treat any type of infertility problem, with the exception of the following:
Tubal obstruction.
Tubal injury is severe.
A uterine anatomic condition, such as severe intrauterine adhesions.
Sperm that can’t get through to an egg.
Couples who have failed five to six rounds of ovarian stimulation with intrauterine insemination and have failed to conceive after at least a year of trying frequently choose ZIFT (IUI).
Similarities and distinctions between ZIFT and in vitro fertilisation (IVF)
Women who have more serious infertility concerns, such as damaged fallopian tubes, may benefit from both ZIFT and IVF.
Both involve the cultivation of embryos.
Both ZIFT and IVF give the doctor the option of selecting only the highest-quality embryos for transfer.
The fertilised embryo is transferred into the fallopian tube using ZIFT, whereas the fertilised embryo is transferred into the uterus with IVF and embryo transfer.
The transfer of embryos into the tube in the ZIFT process varies from IVF in that it involves an additional surgical procedure called laparoscopy.
Conclusion
Zygote intrafallopian transfer (ZIFT) is an assisted reproductive technology (ART) that was initially used in 1986 to help infertile couples get pregnant. In vitro fertilisation (IVF) and gamete intrafallopian transfer (GIFT) methods have been combined to create ZIFT. Despite a success rate that is comparable to IVF, it is less frequent than its parent procedures due to higher costs and more invasive processes. However, some patients prefer ZIFT because the fertilised oocyte, known as the zygote, is implanted in the woman’s body for implantation considerably sooner than with IVF.
