What is IVF Treatment and how does it work?

In Vitro fertilization allude to the procedure where sperms and eggs are brought together and stored in a controlled environment for fertilization. Depending on the health of the sperm or egg one can use their own sperm or egg or donor’s sperm or egg for incubation. After IVF one or more fertilized eggs are placed in uterus.

Every couple seeking fertility treatments are filled with hopes of fulfilling their dreams of having their precious one. IVF (In Vitro Fertilisation) treatment has managed to attain considerable success in it as well. However, it is a complex procedure, consisting of various steps, the feasibility and success of which are based on a variety of factors.

IVF Treatment for Infertility

IVF can be used to treat infertility in the following patients:

Apart from the external reasons for infertility mentioned earlier biological reasons also lead to infertility. The external factors are:

1) Infertility has been a rising problem especially in the last decade with massive changes in lifestyle and stress related to that.

2) Career women who decide to conceive at a later stage in life also face issues of infertility.

3) Infertility in men arises from low sperm count, poor sperm quality or both. The infertility in men could be traced to stress-related issues, addiction to alcohol, drugs and smoking, and possibly hereditary issues.

Infertility Causes :

1) A woman does not have fallopian tubes or in case it is blocked.

2) Endometriosis which cause severe abdomen pain

3) A man having low sperm count

4) Unexplained infertility

What is the IVF process step by step?

There are five basic steps in the IVF and embryo transfer process:

Step 1: Medication

The woman is given injection hormones to stimulate healthy egg development. IVF helps her produce more eggs than she would in a normal month.

Multiple eggs are collected because some eggs will not develop or fertilize after retrieval. A transvaginal ultrasound is used to examine the ovaries, and blood test samples are taken to check hormone levels.

Step 2:Eggs are retrieved through a minor surgical procedure

Step 3: The male is asked to produce a sample of sperm, which is prepared for combining with the eggs.

Step 4: In a process called insemination, the sperm and eggs are mixed together and stored in a laboratory dish to encourage fertilization.

Step 5: After three to five days following egg retrieval , the fertilized embryos are transferred into the woman’s uterus. For tranfering embroyos a catheter or small tube is inserted into the uterus. This painless procedure may cause mild cramping for most women.Implantation typically occurs around six to ten days following egg retrieval for successful procedure.

In Vitro Fertilisation, as mentioned earlier, involves a series of procedures and medications. All of these steps play a vital role in the success of the treatment, which is the birth of a healthy baby.

The major factors that affect the implantation rates or outcome of an IVF treatment include the egg and sperm quality, the ovulation timing and stimulation protocol used, the receptivity of endometrium for implantation of the embryo, embryo quality and embryo transfer.

What is the success rate of in vitro fertilization? Factors Affecting IVF Success Rate

  • Age plays a major role in the egg quality. While women have a high chance of successful conception within a few IVF cycles, at an age below 35 years, the probability for speedy impact reduces beyond that age. The success rate of IVF in women in their 40s is considerably less. This is due to the changes in ovulation pattern with a decrease in ovarian reserve due to increasing age.

  • The type of stimulation protocol used and the accurate timing of ovulation are necessary for extracting the right quality egg for artificial fertilisation in an IVF cycle. Egg quality has a lot to do with its ability for implantation. The maturation and development of eggs following stimulation should be carefully monitored. This helps in extracting eggs that are not too matured or immature. Timing the egg extraction varies from one patient to the other.

  • Receptivity of endometrium is a major factor affecting the implantation rates during IVF. Some anatomical abnormalities in the uterus are known to be a cause of subfertility. The growth of fibroids or polyps in the endometrial cavity or adjacent to it might interfere with the implantation of the embryo. Intrauterine adhesions also hamper the implantation process, resulting in frequent miscarriages.

  • In some women, a thin endometrial lining that is lesser than 8 mm in thickness can result in failed IVF procedures. Immunological factors contribute to failure in implantation as well. Embryo transfer is a major procedure in an IVF cycle. It is carried out with great care and ultrasound is used for the optimal placement of embryo to provide the maximum possibility for implantation.

We are dedicated and very well aware of your dream of a baby. We are well aware of the physical, financial and emotional effects of the treatment and hence consider it important to inform the patients of the factors that influence the success of the procedure.

One of the wonders medical science presented us was the artificial incubation eggs and the power to choose the healthiest of them to create life. In Vitro has come as a stroke of luck for those healthy couples who want to celebrate the bliss of giving birth to a child artificially. By circumventing the most natural process medical science meets technology to aid in giving birth artificially.
