Fertility Clinic in Delhi

At KIC Delfinium, top Fertility Clinic in Delhi, we are committed to providing clear, thorough information to help you make well-informed decisions. Let’s explore what IVF and ICSI are, how they differ, and which one might be right for you.

 What Is IVF and ICSI?

Both In Vitro Fertilization (IVF) and Intracytoplasmic Sperm Injection (ICSI) are techniques that involve fertilizing an egg outside the body in a lab. The goal is to create healthy embryos, which are then transferred into the uterus for pregnancy.

The key difference lies in the process of fertilization.

 IVF: A Natural Approach to Fertilization

In an IVF procedure, the eggs are retrieved from the ovaries and placed in a laboratory dish with sperm. Fertilization occurs naturally, with one sperm entering and fertilizing the egg. This method allows the sperm and egg to meet without any intervention, creating a more natural fertilization process.

ICSI: A Targeted Fertilization Technique

ICSI is a more specialized approach, where a single sperm is directly injected into the egg using a very fine needle. This is particularly useful when there are sperm-related issues, such as low count, poor motility, or abnormal morphology, which may prevent natural fertilization.

 Key Differences Between IVF and ICSI

Here’s a quick comparison:
Feature 
IVF
ICSI
Fertilization Method Natural sperm-egg interaction Single sperm injected into egg
Best For Mild infertility, general fertility issues Severe male infertility or past IVF failures
Sperm Quality Healthy sperm required Can be used with low sperm count or motility issues
When Should You Choose IVF?

IVF is typically recommended when:

* Fallopian tubes are blocked or damaged

* Ovulation issues such as PCOS

* Conditions like endometriosis or pelvic scarring

* Mild male infertility

* Genetic screening is needed (PGT)

* Sperm is of normal quality, and fertilization issues lie elsewhere

IVF can be effective when the primary issue does not involve sperm quality.

When Is ICSI the Best Option?

ICSI is suggested in situations where sperm quality is a concern. You may be a candidate for ICSI if:

* Sperm count is extremely low

* Sperm motility is poor

* Sperm shape is abnormal

* DNA fragmentation in sperm is high

* Surgical sperm retrieval is necessary

* Previous IVF cycles failed due to fertilization issues

By selecting and injecting a single sperm, ICSI improves the chances of fertilization.

What Is IMSI?

IMSI (Intracytoplasmic Morphologically Selected Sperm Injection) is an advanced version of ICSI that uses a microscope with up to 6000x magnification to carefully select the sperm with the best morphology and least DNA damage. IMSI is considered when:

 

* Embryo quality has been poor in previous cycles

* Fertilization attempts have failed repeatedly

* There is severe male infertility

How to Choose Between IVF, ICSI, or IMSI?

Your fertility expert will consider your unique situation, including test results and any past fertility experiences, to recommend the best treatment. Here’s a quick guide:

Choose IVF if :

* You have ovulation or tubal issues, or mild male infertility

* Your sperm quality is good enough for natural fertilization

* You are younger with a good ovarian reserve

Opt for ICSI if :

* There’s severe male infertility

* Past IVF cycles have failed due to fertilization problems

* Sperm needs to be surgically retrieved

* High sperm DNA fragmentation is a concern

Consider IMSI if :

* Previous cycles produced poor embryos or failed

* Sperm quality is a significant concern

* Male infertility is severe
