What Are the Different Types of Assisted Reproductive Technologies?

Assisted reproductive technologies are meant for helping couples in overcoming the infertility challenges. But, still there are certain infertility issues that cannot be reversed using assisted reproductive technologies. The success rate of the assisted reproductive technologies is around 37% in women below 35 years of age; as women reach their 40s, the success rate drops by 11%. Below we have discussed about the four types of assisted reproductive techniques in practice currently.

1) In vitro fertilization :

This is probably the most widely used technique for inducing assisted reproduction. During this procedure, the doctor harvests eggs within the woman’s body by offering her medications for promoting ovulation. The ovulation drugs increase the egg production by a woman’s ovaries. Next, these eggs get removed and placed in the petri dish; this is where the eggs get exposed to the sperm and fertilization occurs. The eggs should be kept in the state of fertilization for 3 to 5 days. The next step of in vitro fertilization is implantation of the embryos into the uterus of the woman. If the process works correctly, the embryos will grow into fetuses. As through this procedure several embryos can be implanted, it can be used for multiple birthsz.

2)  Intrafallopian transfer :

Intrafallopian transfers can be of two types, zygote intrafallopian transfer and gamete intrafallopian transfer. The steps involved in the first one resemble that of the in vitro fertilization significantly. However, unlike in vitro fertilization, in this procedure the embryos get placed in the fallopian tubes of the woman and not in her uterus. Then, the implanted embryo will travel through fallopian tubes and reach the uterus. Gamete intrafallopian transfer is not used frequently; fertilization during this assisted reproduction technique does not occur outside the body of the woman. During gamete intrafallopian transfer, both sperm and eggs get transferred into the woman’s fallopian tubes, where the eggs get fertilized. After occurrence of fertilization, the embryo enters the uterus.

3) Intracytoplasmic sperm injections :

This assisted reproductive technique is recommended to couples, who are suffering from infertility due to problems with viability of sperm. During this procedure, a single healthy sperm gets injected into egg. After occurrence of fertilization, the embryo gets shifted to either fallopian tube or uterus.
