What Is the Most Successful IVF Cycle Stage in Navi Mumbai?

Infertility is growing among the current generation because of their poor lifestyle habits and the untimely detection of certain hidden health issues. Therefore, most couples are turning towards in vitro fertilisation (IVF) to live their dream of becoming parents to a little one. However, they usually have multiple questions before opting for the procedure, as it is completed in several steps. The couples want to know the most successful stage of the complete IVF cycle to take precautions beforehand. In Navi Mumbai, most clinics suggest that the blastocyst stage of embryo transfer directly impacts the success of pregnancy and gives great results.

So why is this a successful IVF cycle stage? Why are so many fertility experts advising waiting until Day 5 rather than transferring sooner? And how many IVF cycles does it take to get pregnant? Let's answer all your queries in this blog, so you feel a bit more assured.

Key Steps of the One IVF Cycle

Before you learn more about the most successful IVF cycle stage, let’s quickly understand the key steps involved in an IVF cycle:

1. Ovarian Stimulation

The process begins with hormone medications given to the female partner for ovarian stimulation. Instead of releasing one egg, as happens naturally, the ovaries produce multiple mature eggs. This increases the chances of fertilisation and helps in creating viable embryos.

2. Egg Retrieval

After the eggs are mature (the embryologist typically verifies that through ultrasound and blood work, hormone levels), they are retrieved in a brief, low-risk procedure known as egg retrieval. The female partner is given light sedation, and the entire process takes only about 20–30 minutes.

3. Fertilisation in the Lab

The retrieved eggs are then fertilised with sperm in a lab setting. This step can be completed through two methods.

• In traditional fertilisation, sperm and egg are combined outside the body in a lab setting.
• Another one is ICSI (Intracytoplasmic Sperm Injection), in which a single sperm is injected into an egg directly (usually in situations where there is male infertility).

After being fertilised, the eggs start developing into embryos.

4. Embryo Development

In the coming days, the laboratory staff will closely check the developing embryos. The embryos will have about 6-8 cells by Day 3. A few of them would continue developing to an older age, called a blastocyst by Day 5. All embryos do not grow to this stage of development. Hence, this stage assists in choosing the best embryos that can provide greater opportunities for success.

5. Embryo Transfer

At this point, one (or sometimes two) of the healthy embryos is transferred into the womb. Although transfers may be done at either the Day 3 or Day 5 stage, however, the majority of fertility experts recommend that Day 5 blastocyst transfers are more likely to be successful. The reason is that by then the embryo has already proven its ability to develop and split well, and hence it is easier to select the healthiest one for transfer.

The transfer itself is fast, pain-free, and does not need anaesthesia. It's performed under ultrasound guidance with a flexible, thin tube to implant the embryo directly into the lining of the uterus.

6. Support During the Luteal Phase

Following the embryo transfer, fertility specialists also offer hormonal support, with progesterone and occasionally estrogen, to prepare the uterus for implantation. This stage is important to maintain early pregnancy and increase the likelihood of proper embryo implantation.

Most Important IVF Cycle Stage: Blastocyst Transfer

After fertilisation, embryos begin to grow. By Day 3, they usually become a mass of 6-8 cells. On Day 5, some embryos grow to become an even more complex form known as a blastocyst. At this point, embryos continue to develop to become a mass of tissue about 100-150 cells with a fluid-filled cavity.

Hence, the blastocyst transfer simply means transferring the matured embryo into the uterus instead of the earlier stage at Day 2 or Day 3.

Blastocyst Transfer: Why Is It More Successful

If you have made it this far in the IVF journey, you want to give yourself the best possible chance of success. That’s why the timing of embryo transfer matters. Several reasons make embryo transfer at blastocyst a successful IVF cycle stage, which are discussed as follows:

1. Natural Timing with the Body

In a natural pregnancy, a fertilised egg reaches the uterus about five days after ovulation. Transferring a Day 5 blastocyst into the uterus better mimics this timing. This increases the chances of implantation.

2. Viable Embryos

Not all embryos survive until the blastocyst stage. Only the healthiest embryos reach this stage. This implies the embryo being transferred is already past a critical development hurdle and would require help only for implantation.

3. Improved Selection Accuracy

When fertility specialists wait till Day 5, they gain time for close observation to examine which embryos are developing well. This provides them with a higher accuracy to choose the optimum embryo for transfer and succeed in the initial cycle itself.

4.  Increased Implantation Rates

As per several research works, blastocyst transfers have greater implantation and pregnancy rates than transfers at an earlier stage. For the couples who are going through IVF in Navi Mumbai, this is a factor that becomes most important to understand regarding this stage for a successful pregnancy.

Importance of Proper Monitoring During the Luteal Phase

What happens after the embryo is placed into the uterus is equally important. This is referred to as the luteal phase, between the time of ovulation and the supposed period. It is an important window for the implantation of the embryo. Once the embryo has been placed into the uterine environment, the body needs to be hormonally prepared to ensure that it can attach and develop in the first stages. Clinics that share detailed data on IVF cycle cost and results in Navi Mumbai often highlight how this phase impacts success rates. Here are some additional reasons why luteal phase monitoring is important:

• Facilitates embryo implantation by maintaining uterine lining thickness and receptivity.
• Tracks progesterone levels to determine if additional hormonal support is needed.
• Identifies early hormonal imbalances that could interfere with pregnancy.
• Improves chances of a successful outcome in both first and subsequent IVF cycles.
• Informs treatment adjustments for better planning in case of implantation failure.
• Helps stabilise early pregnancy by maintaining ideal hormonal conditions.

Major Factors Affecting The IVF Success

While blastocyst transfer is generally more successful, it’s important to understand that IVF results vary. So, how many IVF cycles does it take to get pregnant? Several women conceive after the first cycle only. However, others may need 2 to 3 cycles or more, based on their individual case and physiology. To make consideration easy for you, here’s a list of factors that influence the overall IVF success rate in Navi Mumbai:

• Age of the Woman – Fertility is directly depended on age in the case of women. It declines especially after 35.
• Egg Quality – Healthy eggs increase embryo survival to the blastocyst stage.
• Sperm Health – Good sperm quality improves fertilisation rates.
• Underlying Health Conditions – Conditions like PCOS, thyroid issues, or endometriosis may affect success.
• Previous Failed Cycles – Help doctors make better adjustments for future attempts.
• Success Rate of Frozen Embryo Transfer – FET can improve outcomes, especially when the uterine lining is more receptive during natural or hormone-controlled cycles.

How to Know if You Are a Candidate for Blastocyst Transfer

Not all will respond equally well to blastocyst transfer. Best candidates usually:

• Develop a good number of high-quality embryos following fertilisation
• Possess a healthy uterine lining to support implantation of the embryo
• Are having IVF for the first or second time
• Have no significant uterine anomalies
