What is IVF?
IVF stands for In Vitro Fertilization, and it's a medical procedure used to help couples who are struggling to conceive a baby naturally. Here's a simplified explanation of how IVF works:
Stimulation: The woman undergoing IVF is given hormone medications to stimulate her ovaries to produce multiple eggs instead of just one during her monthly cycle. These medications are usually taken as injections.
Monitoring: Throughout the stimulation process, the woman's doctor will closely monitor the growth and development of the eggs using ultrasound scans and hormone level tests.
Egg retrieval: Once the eggs have matured, a minor surgical procedure called egg retrieval is performed. The woman is given anesthesia, and a thin needle is used to remove the eggs from her ovaries. This procedure usually takes about 20-30 minutes.
Fertilization: The retrieved eggs are then combined with the partner's or donor's sperm in a laboratory dish. The sperm can either be added to the eggs or injected directly into the eggs using a process called intracytoplasmic sperm injection (ICSI). This allows for the fertilization of the eggs and the formation of embryos.
Embryo development: The fertilized eggs, now called embryos, are incubated in a laboratory for a few days to allow them to develop and grow.\
Embryo transfer: Once the embryos have reached a certain stage of development, usually around 3-5 days, they are transferred into the woman's uterus. This procedure is done using a thin catheter, and it's typically painless and doesn't require anaesthesia.
Pregnancy test: About two weeks after the embryo transfer, the woman takes a pregnancy test to determine if the IVF procedure was successful.
That's a simplified overview of the IVF process. It's important to note that IVF can be a complex and emotional journey for couples, and success rates can vary depending on various factors such as the woman's age and overall health. It's always best to consult with a fertility specialist for personalized information and guidance.
Why and when IVF is recommended?
IVF is recommended in several situations when couples are facing difficulties in conceiving a baby naturally. Here are some common reasons why and when IVF may be recommended:
Infertility: IVF is often recommended for couples who have been diagnosed with infertility. Infertility can have various causes, such as blocked fallopian tubes, low sperm count or motility, ovulation disorders, endometriosis, or unexplained infertility. IVF can bypass these issues and increase the chances of pregnancy.
Advanced maternal age: As women age, the quantity and quality of their eggs decrease, making it more challenging to conceive. IVF can help by using fertility medications to stimulate the ovaries and retrieve multiple eggs for fertilization.
Ovulatory disorders: Women who have irregular or absent ovulation may benefit from IVF. The stimulation medications used in IVF can help induce ovulation and improve the chances of successful fertilization.
Endometriosis: Endometriosis is a condition where the tissue lining the uterus grows outside of it, causing fertility problems. IVF can help bypass the effects of endometriosis by retrieving eggs and fertilizing them outside the body before transferring them to the uterus.
Male factor infertility: IVF can be recommended when the male partner has issues with sperm quality, low sperm count, or problems with sperm motility. In such cases, ICSI (intracytoplasmic sperm injection) can be used during the IVF process to directly inject a single sperm into each egg for fertilization.
Genetic disorders: If either partner carries a genetic disorder that they don't want to pass on to their child, IVF with preimplantation genetic testing (PGT) can be recommended. PGT involves testing the embryos created through IVF for specific genetic conditions before transferring them to the uterus.
How does IVF differ from other treatment options?
IVF differs from other treatment options for infertility in several ways. Here are some key differences between IVF and other common treatments:
Ovulation Induction and Intrauterine Insemination (OI/IUI): OI/IUI involves stimulating the ovaries to produce eggs and then placing washed and prepared sperm directly into the uterus around the time of ovulation. This method is less invasive and less expensive than IVF. However, it is typically recommended for couples with mild fertility issues, such as low sperm count or unexplained infertility. IVF is more suitable for more complex fertility problems or when OI/IUI has not been successful.
Gamete Intrafallopian Transfer (GIFT) and Zygote Intrafallopian Transfer (ZIFT): GIFT and ZIFT are procedures like IVF but involve transferring eggs and sperm or fertilized embryos directly into the fallopian tubes instead of the uterus. These techniques are less commonly used today, and IVF has become the preferred method due to its higher success rates and greater control over the fertilization process.
Donor Conception: In cases where one or both partners are unable to produce eggs or sperm, or there is a high risk of passing on genetic disorders, donor eggs, sperm, or embryos can be used for conception. IVF is the method used to combine the donated gametes (eggs and sperm) or embryos and transfer them to the woman's uterus. Other treatments like OI/IUI may not be effective or feasible in these situations.
Surrogacy: Surrogacy involves a woman carrying a pregnancy on behalf of another person or couple. IVF is often used in surrogacy arrangements to create embryos using the intended parents' gametes or donated gametes and then transferring the embryos to the surrogate's uterus. Other treatments may not be suitable for achieving pregnancy in surrogacy cases.
Preimplantation Genetic Testing (PGT): PGT can be performed during IVF to screen embryos for genetic disorders before transfer. This allows couples with known genetic conditions or a history of recurrent pregnancy loss to select embryos that are free of the disorder. Other treatments do not typically involve this level of genetic screening and selection.
How is life after IVF?
Life after IVF can vary greatly for different couples and individuals. Here are some aspects to consider when thinking about life after IVF:
Pregnancy and Parenting: The goal of IVF is to achieve a successful pregnancy and have a baby. If the IVF procedure is successful, couples may experience the joy of pregnancy and the journey of becoming parents. However, it's important to note that IVF does not guarantee a pregnancy, and multiple cycles may be required for success. If a pregnancy is achieved, the experience of pregnancy and parenting will be like that of any other couple who conceives naturally.
Emotional Rollercoaster: IVF can be emotionally challenging due to the ups and downs of the process. Couples may experience feelings of hope, anticipation, disappointment, frustration, and anxiety throughout the treatment. The emotional impact can continue even after a successful pregnancy, as there may be concerns about the health of the baby or the adjustment to parenthood.
Support Networks: Many couples find support and solace in connecting with others who have gone through or are going through IVF. Support groups, online forums, and counseling services can provide valuable emotional support and information-sharing opportunities.
Continued Medical Monitoring: Even after a successful IVF and pregnancy, there may be a need for continued medical monitoring, especially in high-risk pregnancies or cases where certain health conditions are present. Regular check-ups, ultrasounds, and consultations with healthcare providers may be required.
It's essential to remember that every individual's experience with IVF is unique. Some may achieve success quickly, while others may face additional challenges. Building a strong support system, seeking emotional support when needed, and maintaining open communication with healthcare providers can help navigate the post-IVF journey.

Who is a candidate for IVF?
IVF is commonly recommended for couples who have been trying to conceive for a significant period without success or for those with specific fertility issues. It may be suitable for couples with blocked fallopian tubes, low sperm count or motility, endometriosis, or unexplained infertility.
Does IVF guarantee a successful pregnancy?
IVF does not guarantee a successful pregnancy, but it increases the chances of conception for couples with fertility challenges. Success rates depend on various factors, including the quality of the eggs and sperm, the age of the woman, and the expertise of the fertility clinic.
How many embryos should be transferred during IVF?
The number of embryos to transfer depends on various factors, including the woman's age, the quality of the embryos, and any previous IVF outcomes. The goal is to achieve a successful pregnancy while minimizing the risk of multiple pregnancies. Guidelines and regulations in different regions may also influence the number of embryos that can be transferred.
Are there any alternatives to IVF?
Depending on the underlying fertility issue, there may be alternative treatments to IVF. These can include intrauterine insemination (IUI) for certain cases, fertility medications to stimulate ovulation, or surgical interventions to address specific anatomical factors. The most suitable treatment options are determined by a thorough evaluation of everyone’s situation.
How long does an IVF cycle take?
The duration of an IVF cycle can vary, but it typically takes around 4-6 weeks. This includes ovarian stimulation, egg retrieval, fertilization in the laboratory, embryo development, and the embryo transfer process. The specific timeline may vary depending on individual circumstances and treatment protocols.
Are there any risks or side effects associated with IVF?
While IVF is generally safe, it may involve certain risks and side effects. These can include ovarian hyperstimulation syndrome (OHSS), multiple pregnancies, ectopic pregnancies, or minor discomfort during the egg retrieval procedure. Your fertility specialist will discuss the potential risks and side effects with you before proceeding with treatment.
Can frozen embryos be used in IVF?
Yes, frozen embryos can be used in IVF. Embryos that are not transferred immediately can be frozen for future use. Frozen embryo transfer (FET) cycles can be performed at a later time, offering additional chances for pregnancy without going through a full IVF cycle.
