Couples considering IVF treatment in Pakistan often ask a vital question: What determines the success of an IVF cycle While IVF has become a widely accessible and trusted fertility solution across Pakistan, success is not guaranteed and several medical and personal factors can influence the outcome.
1. Age of the Woman
Age is one of the biggest factors affecting IVF success.
- Women under 35 have the highest success rates due to better egg quality and higher ovarian reserve.
- Women aged 35–40 may still have success with IVF, but the chances decrease.
- After 40, success rates drop significantly unless donor eggs are used.
This is why early fertility evaluation is crucial, especially for women with irregular cycles or other health concerns.
2. Egg and Embryo Quality
Good-quality eggs lead to good-quality embryos—essential for implantation and pregnancy. Egg quality is impacted by:
- Age
- Hormonal imbalances (like PCOS or thyroid issues)
- Past ovarian surgeries or medical conditions
- Genetic factors
Fertility clinics use blastocyst culture and embryo grading systems to identify the healthiest embryos for transfer, which boosts success chances.
3. Sperm Health
Male infertility also plays a significant role in IVF outcomes. Factors like low sperm count, poor motility, or abnormal morphology affect fertilization rates. In such cases, clinics use ICSI (Intracytoplasmic Sperm Injection) to directly inject a single healthy sperm into an egg.
Advanced sperm selection techniques now improve outcomes for men with azoospermia or other serious sperm issues.
4. Fertility Clinic’s Technology and Expertise
Not all clinics offer the same level of care. IVF success depends heavily on the clinic’s:
- Laboratory standards
- Experience of embryologists
- Availability of services like ICSI, PGD, time-lapse embryo monitoring, and vitrification
- Proper handling and culture of embryos
- Ethical and personalized treatment plans
Top centers like Australian Concept Infertility in Pakistan are known for their advanced technology and skilled fertility experts, contributing to higher success rates.
5. Uterine Health and Endometrial Receptivity
Even with a high-quality embryo, implantation may fail if the uterus is not healthy. IVF success is more likely when:
- The endometrial lining is of proper thickness (typically 7–10mm)
- There are no fibroids, polyps, or uterine abnormalities
- Hormone levels are well-balanced for transfer
Doctors may recommend additional testing, such as hysteroscopy or ERA (Endometrial Receptivity Analysis), to assess and prepare the uterus for implantation.
6. Underlying Health Conditions
Conditions such as:
- PCOS (Polycystic Ovary Syndrome)
- Thyroid disorders
- Obesity
- Diabetes
- Endometriosis
can reduce IVF success rates. However, with proper diagnosis and pre-treatment, these issues can often be managed effectively before starting IVF.
7. Lifestyle and Emotional Well-Being
Your body and mind are deeply connected, especially during fertility treatment. Lifestyle habits that influence IVF success include:
- Maintaining a healthy weight
- Quitting smoking and alcohol
- Managing stress and anxiety
- Getting quality sleep
- Eating a balanced diet rich in nutrients
Some clinics in Pakistan now offer nutrition and stress management support alongside IVF, helping patients prepare both physically and mentally.
8. Number and Quality of Embryos Transferred
- Transferring more than one embryo may increase pregnancy chances but also raises the risk of twins or complications.
- Most good clinics aim to transfer 1 or 2 high-quality embryos to balance safety and success.
Doctors decide based on your age, fertility history, and embryo quality.
