What is In Vitro Fertilization (IVF)?

In vitro fertilization (IVF) is a complex and controlled procedure carried out by expert doctors. During this process, mature eggs (ova) from the ovaries and mature sperm are combined outside the body in a laboratory setting. This is done through a specific procedure to facilitate the journey of the sperm to the egg and to make it easier for the egg to be fertilized. Once the fertilized egg is formed, it is nurtured in an artificial environment for about 5 days. This artificial environment closely resembles the conditions inside the human body. After 5 days, the developed fertilized egg is placed near the uterine lining using a specialized catheter, making it easier for the egg to implant.

Following this, hormones, particularly progesterone, are administered to support the attachment of the fertilized egg. About 2 weeks later, a blood test (Serum BhCG) is conducted, and around 6 weeks later, an ultrasound is performed to ensure the well-being of the developing fetus inside the womb.

How Does Pregnancy Occur (Normal Pregnancy – How it Actually Happens)?

In simple terms, after girls reach around 13-14 years of age, the menstrual cycle begins. In this cycle, every month, one mature egg is released from the ovary, and it has to meet with a sperm within 24 hours for pregnancy to potentially happen. If the egg doesn’t meet a sperm, it dissolves, and the menstrual period starts again. This process continues until the age of 45-55.

If a mature egg from the ovary meets a sperm within 24 hours, the process of becoming pregnant begins. During this, there is competition among millions of sperm, and eventually, one sperm penetrates the mature egg, leading to the formation of a fertilized egg. After 7 days, the fertilized egg attaches itself to the mother’s uterus, and over a period of 40 weeks, it develops into a mature fetus, eagerly awaited by the parents to join the outside world.

However, if there are any natural obstacles in this process, such as immature eggs, difficulties in the sperm’s journey to the egg, or challenges in the attachment of the fertilized egg to the uterus, the couple might not be able to conceive naturally. In such cases, a solution is in vitro fertilization (IVF).

When is In Vitro Fertilization (IVF) Needed?

In vitro fertilization (IVF) is needed in various situations where natural conception is not possible. These include:

1. Unexplained Infertility: When couples are unable to conceive without any clear medical reason.
2. Fallopian Tube Abnormality: If there are issues with the fallopian tubes that prevent the egg from traveling to the uterus or sperm from reaching the egg.
3. Failed Intrauterine Insemination (IUI): After multiple unsuccessful attempts of intrauterine insemination, where sperm is placed directly into the uterus.
4. Severe Endometriosis: A condition where tissue that normally lines the uterus grows outside the uterus, affecting fertility.
5. Abnormal Semen: If the male partner has issues with sperm count, motility, or morphology.
6. Surgical Retrieved Sperm: In cases where sperm cannot be naturally ejaculated and need to be retrieved surgically.

In these situations, IVF offers a viable option for couples to achieve pregnancy. It involves fertilizing the egg and sperm outside the body in a controlled environment, and then implanting the resulting embryo into the uterus. This technique bypasses the challenges posed by the mentioned conditions.

The success rate of in vitro fertilization (IVF) is approximately 55%. The success of IVF depends on three key factors:

1. Age: The age of both the female partner and the quality of her eggs significantly impact the success of IVF. Generally, younger women have a higher chance of success, as the quality of their eggs is better.
2. Ovarian Reserve: The quantity and quality of eggs stored in the ovaries, known as ovarian reserve, play a crucial role. A good ovarian reserve increases the likelihood of obtaining viable eggs for fertilization.
3. Previous Results: The outcomes of any previous IVF cycles or fertility treatments can also influence the success of subsequent attempts.

It’s important to note that success rates can vary based on individual circumstances and the specific clinic’s expertise. Factors such as overall health, underlying medical conditions, lifestyle, and the quality of the fertility clinic all contribute to the IVF success rate.

Causes of Male Infertility:

Male infertility can be attributed to various factors, including:

1. Abnormal Sperm Production: Issues with sperm quality and quantity, leading to abnormal sperm production.
2. Sperm Motility Issues: Problems with the movement and mobility of sperm.
3. Varicocele: Enlarged veins within the scrotum that can affect sperm health.
4. Infections: Infections that impact the reproductive organs and sperm production.
5. Genetic Factors: Genetic conditions affecting sperm production or function.
6. Lifestyle and Environmental Factors: Daily habits, exposure to environmental toxins, and unhealthy lifestyle choices.
7. Hormonal Imbalances: Imbalances in hormone levels that regulate sperm production.
8. Testicular Trauma: Injuries to the testicles affecting sperm production.
9. Radiation Therapy: Exposure to radiation, such as during cancer treatment.
10. Autoimmune Disorders: Autoimmune conditions affecting sperm health.
11. Structural Abnormalities: Anatomical irregularities in the reproductive system.
12. Obesity: Excess body weight affecting hormone levels and sperm production.
13. Chronic Illnesses: Long-term medical conditions like diabetes or kidney disease impacting fertility.
14. Medications: Certain medications, like anabolic steroids or antihypertensives, affecting sperm production.
15. Age-Related Decline: Reduced sperm quality and quantity with increasing age.
16. Occupational Exposures: Exposure to chemicals or toxins at the workplace.
17. Psychological Factors: Emotional stress or psychological issues affecting sexual function and fertility.
18. Poor Nutrition: Inadequate diet and nutritional deficiencies impacting sperm health.
19. Smoking and Alcohol Use: Consumption of tobacco and alcohol negatively affecting sperm quality.

It’s important to understand that male infertility can result from a combination of these factors, and each case may be unique. If a couple is facing infertility issues, both partners should undergo thorough evaluations to determine the underlying causes.

Causes of Female Infertility:

Female infertility can stem from various factors, including:

1. Pelvic Inflammatory Disease (PID): Infections affecting the reproductive organs, particularly the fallopian tubes.
2. Blocked Fallopian Tubes: Obstruction of the fallopian tubes, preventing the egg from reaching the uterus.
3. Endometriosis: A condition where tissue similar to the lining of the uterus grows outside the uterus.
4. Uterine Fibroids: Noncancerous growths in the uterus that can interfere with conception.
5. Polycystic Ovary Syndrome (PCOS): Hormonal imbalance leading to irregular ovulation and cyst formation on the ovaries.
6. Hormonal Imbalances: Irregularities in hormone levels affecting the menstrual cycle and fertility.
7. Ovulation Disorders: Issues with the release of mature eggs from the ovaries.
8. Old Age: Decreased fertility with advancing age.
9. Autoimmune Disorders: Autoimmune conditions impacting fertility.
10. Genetic Factors: Genetic conditions affecting reproductive health.
11. Thyroid Disorders: Imbalances in thyroid hormone levels affecting fertility.
12. Chronic Illnesses: Long-term medical conditions that can affect fertility.
13. Medications: Certain medications that can impact fertility.
14. Excessive Exercise or Low Body Weight: Extensive physical activity or low weight affecting hormone balance.
15. Smoking and Alcohol Use: Consumption of tobacco and alcohol negatively affecting fertility.
16. Stress and Emotional Factors: Psychological stress impacting the menstrual cycle and fertility.
17. Occupational Exposures: Exposure to chemicals or toxins at the workplace.
18. Surgeries or Medical Procedures: Certain surgeries or medical interventions affecting reproductive organs.
19. Autoimmune Disorders: Autoimmune conditions affecting fertility.

It’s important to recognize that female infertility can result from a combination of these factors, and each case may be unique. If a couple is facing infertility issues, both partners should undergo comprehensive evaluations to determine the underlying causes.
