Knowledge | In Vitro Fertilization: Hope in Modern Infertility Treatment


In vitro fertilization (IVF) is now a common treatment for infertility, but it was a mysterious procedure not long ago. The first baby conceived through IVF was born in the United Kingdom in 1978. Unlike artificial insemination, IVF combines an egg and sperm in a laboratory before transferring an embryo to the uterus. Although IVF is complex and costly, 1.9% of infants have been born through IVF or other assisted reproductive technology (ART) since its introduction in the United States in 1981.

1. Which Types of Infertility Can IVF Treat?

IVF is used for many causes of infertility, including:


Endometriosis

Low sperm count

Uterine or fallopian tube problems

Ovulation disorders

Antibody problems that damage sperm or eggs

Sperm unable to penetrate cervical mucus

Poor egg quality

A genetic disorder in either parent

Unexplained infertility

IVF is usually not the first infertility treatment unless the fallopian tubes are completely blocked. Doctors often recommend it after medication, surgery, or artificial insemination has not worked.


2. The IVF Process

The first step is hormonal injections that stimulate the ovaries to produce multiple eggs. Blood tests and ultrasound are used to assess egg maturity. Once the eggs reach the appropriate stage, they are retrieved and combined with the partner's sperm in a laboratory. After embryos form, they are transferred to the uterus.

The process requires careful timing because retrieving eggs too early or too late can affect development. After fertilization, embryos are observed for several days to confirm optimal development. The doctor then transfers them to the uterus. The article states that 1 to 3 embryos are typically recommended to improve the chance of pregnancy.


3. IVF Success Rates

Success rates vary by cause of infertility, treatment location, use of frozen or fresh eggs, and the woman's age. According to 2018 data, 50% of IVF procedures in women age 35 or younger resulted in a live birth, compared with 3.9% in women age 42 or older.


Age is a major factor in IVF success. Women under 35 have higher success rates using their own eggs, while rates are lower at ages 41 to 42. Multiple transfers may improve the cumulative chance of success.


4. Other IVF Considerations

Embryos not used during the first IVF attempt may be frozen for future use, reducing the cost of later cycles. If a couple does not plan to use remaining embryos, they may donate them to another couple with infertility or ask the clinic to dispose of them. Both partners must agree.


As technology advances, IVF success rates have improved across age groups.
