IVF is an advanced procedure that helps couples who cannot conceive through a natural process. It is an advanced technical process for infertility where eggs are collected from the female and sperm are collected from the male for embryo transfer.
There are step-by-step procedures that should be followed by couples who are looking for pregnancy.
This IVF fertility treatment has both pros and cons. As you can get to know in this blog about IVF is 100% successful or not.
Is IVF treatment 100% successful?
We cannot expect to be completely 100% successful, since age and many other factors can affect the success rate. The success rate of IVF is between 40 to 50% which is completely based on the age of the couples, their body condition, number of cycles they have taken, health conditions and the clinic they choose for the IVF Treatment.
This IVF procedure plays a vital role in transferring the embryo into the female uterus which results in pregnancy. Success rates are high for women who are under the age of 35.
Factors Affecting IVF Success Rates
Several factors affect the IVF success rate.
- Age
- Quality of male sperm
- Quality of female egg
- Analysis of previous pregnancy
- Condition of uterus
- Embryo transfer
- Lifestyle conditions
Age
The age of the female and her body condition are crucial factors in IVF treatment. The success rate of the IVF treatment ranks according to the female age.

Quality of male sperm
There is no need for the exact sperm count. But for motility, the sperm count should be from 5 million to 10 million. The quality and quantity of the sperm should be healthy for IVF treatment. Unhealthy and low sperm motility will affect IVF at a lower rate.
Quality of female egg
The egg count of a female should be 10 to 20, which helps to undergo the treatment easily. The quantity and quality of the eggs should be healthy. The ovulation process should be regular. The eggs should be mature for the reproductive process.
Analysis of previous pregnancy
Women who experienced pregnancies naturally earlier might have a high rate of success for the next baby with IVF treatments.
Condition of uterus
The female uterus must be healthy enough to carry the baby. Thus, having a healthy uterus can leads to a high success rate.
Embryo transfer
The collected egg and the sperm will be analyzed in the lab for fertilization and allowed for embryo culture, and then it will be transferred to the female uterus directly. This process is called embryo transfer. So this procedure helps in giving a high rate of success for pregnancy.

Success Stories of IVF Treatment
The pregnancy rate of IVF has never been 100%. The success rate of IVF will be decided according to the condition of reproductive organs.
There are certain tips to be followed for IVF success.
- Opt for a good and experienced doctor for your treatment. Experienced doctors can examine you properly and will transfer only a single high-quality embryo, whereas the remaining will be frozen for the future cycle.
- The uterus and the embryos should be healthy for fertilization.
- The quality of a female egg, the quality of male sperm, motility, embryos, and the female uterus should be healthy.
- The body weight of a female should be controlled and maintained with a normal BMI.
- A balanced and healthy diet must be followed
- Regular exercise will help to increase the blood circulation level
- Avoid using drugs for better results in treatment

Common reasons for IVF failure
Low quality of sperm and eggs are the common reason for IVF failure. The doctor should examine carefully during the prior test. In many cases, irregular sperm can lead to infertility.
Several common reasons for IVF failure are,
- Age
- Ovary responses
- Quality of egg
- Quality of sperm
- Quality of embryo
- Issues in implantation
- Lifestyle factors
- Endometrial receptivity array
Age
As women grow older the quality and quantity of their eggs will be decreased. Thus the age factor is also a main reason for the lack of success in IVF procedure.
Ovary response
At the beginning of the treatment to increase fertility hormone, Follicle-Stimulating Hormone (FSH) injections should be taken daily to stimulate the production of the eggs. In some cases, the female ovaries will not react to any medication and start producing immature eggs. Thus,ovary response can also affect the success rate of IVF.
Quality of egg
Female hormones will produce a greater number of eggs but in some cases, the eggs will not be developed enough for embryo transfer, so this will also be a reason for IVF failure.
Quality of sperm
Unhealthy male sperm, poor motility, and low-quality sperm will affect the female fertility process, so this is also a major reason for IVF failure.
Quality of embryo
Sometimes, during the time of the fertilization process, all the embryos might not be developed properly because of some genetic disorders. This genetic disorder can lead to failure in IVF.
Issues in implantation
The failure of attachment of fertilized eggs to the uterine lining causes implantation may result in IVF failure.
Lifestyle factors
Smoking, drinking alcohol, and obesity can affect egg quality and hormone levels. So this type of lifestyle should be avoided by couples.
Endometrial receptivity array
At the time of embryo transfer the endometrial receptivity will affect the implantation success between the embryo and the uterine lining. So this causes IVF failure.
Believing the best in doctors and those looking for the best place for IVF can fix your appointment at the best fertility hospital for lifetime happiness and success.
