Peking University Third Hospital IVF Success Rate: Age-Stratified and Clinical Data Interpretation

========== AI Summary ==========

========== Main Text ========== Opening: Real Consultation Scenario

In the reproductive medicine clinic, a 38-year-old woman placed a stack of test reports on the consultation table and asked, "Doctor, my AMH is 1.2, and my antral follicle count is 6. What do you think the IVF success rate is at Peking University Third Hospital? Can I succeed with my condition?"

This is a question repeated every day in the reproductive center. Before answering this question, it is necessary to deconstruct the term "success rate"—for people of different ages, different etiologies, and different embryo statuses, the meaning of this number is completely different. Below, we will clarify this issue from the perspectives of clinical data and doctor's decision-making logic.

===== Module A: Direct Answer =====

IVF Success Rate at Peking University Third Hospital: Reference Range Based on Age and Embryo Type

As one of the first institutions in China to carry out assisted reproductive technology, the Reproductive Center of Peking University Third Hospital has clinical data consistently in the top tier nationally. The following data is compiled from the center's recent annual clinical reports and national reproductive medicine quality control statistics for reference.

Female Age	Clinical Pregnancy Rate (Fresh Embryo Transfer)	Clinical Pregnancy Rate (Frozen Embryo Transfer)	Live Birth Rate After PGT-A
<35 years	55%–65%	60%–70%	65%–75%
35–40 years	45%–55%	50%–60%	55%–65%
40–43 years	25%–40%	30%–45%	40%–55%
>43 years	10%–20%	15%–25%	20%–35%

The above table shows the clinical pregnancy rate (gestational sac seen on ultrasound). The live birth rate is typically 5–10 percentage points lower. Frozen embryo transfer data includes natural cycles and hormone replacement cycles. The live birth rate after PGT-A refers to the live birth rate per embryo transferable after chromosomal screening.

===== Module D: Differences Across Age Groups =====

Age is the Primary Variable Affecting Success Rate

Ovarian response to ovulation induction medications, the rate of normal oocyte chromosomes, and endometrial receptivity all change with age. After age 35, the oocyte aneuploidy rate gradually increases from 20%–25% to 50%–60% at age 40, and exceeds 70% after age 43.

===== Module C: How Doctors View It =====

How Doctors View the "Success Rate" Indicator

In clinical practice, doctors are more concerned with: under what circumstances it is suitable to directly start a cycle, when pre-treatment is needed, and when it is recommended to accumulate embryos and then perform PGT-A. The success rate is not a guarantee, but a probability assessment based on the patient's specific conditions.

===== Module F: Differences Between Hospitals =====

Positioning and Differences of Peking University Third Hospital in the Field

The differences in success rates among domestic reproductive centers are mainly reflected in the following aspects:

• Laboratory Level: The embryology laboratory at Peking University Third Hospital uses time-lapse incubators and AI embryo assessment systems, with a blastocyst formation rate of approximately 55%–65%, higher than the national average (45%–55%).
• PGT Technology: It offers full types of screening including PGT-A, PGT-M, and PGT-SR. Results are available within 24 hours after embryo biopsy, reducing the waiting time for embryos outside the body.
• Multidisciplinary Collaboration: Subspecialties such as reproductive immunology, reproductive endocrinology, hysteroscopy, and genetic counseling are comprehensive, allowing for internal consultations on complex cases.
• Cycle Volume: With over 20,000 cycles per year, clinical doctors and embryologists have extensive accumulated experience.

However, it is important to note: Different hospitals have their own advantageous sub-directions. For example, some centers have more experience in male infertility, egg freezing, and fertility preservation. The choice of hospital should be based on the patient's specific etiology, not just the success rate number.

===== Module G: Most Easily Overlooked Details =====

Hidden Factors Affecting Success Rate

Many patients overlook the following key details when focusing on the success rate:

These details are easily overlooked in routine evaluations but are often key to determining the success of a single transfer.

===== Module H: Common Pitfalls =====

Common Misunderstandings About Success Rate

• Misunderstanding 1: "One success means 100%, two failures mean 0%."——Each transfer is an independent event. A previous failure does not directly reduce the success rate of the next, but the cause of failure needs to be analyzed.
• Misunderstanding 2: "Being young guarantees success."——Even young patients with Polycystic Ovary Syndrome (PCOS) may have many eggs retrieved, but a high proportion of immature eggs and a high risk of OHSS may require freezing all embryos, prolonging the cycle.
• Misunderstanding 3: "The more transfers, the higher the success rate."——Recurrent implantation failure requires investigation into deeper causes like immunity, coagulation, and endometrial receptivity. Simply increasing the number of transfers does not improve the success rate.
• Misunderstanding 4: "PGT (third-generation IVF) has a 100% success rate."——PGT can screen for chromosomal euploidy, but whether an embryo can implant still depends on the uterine environment and endocrine status, and there is a possibility of missing mosaicism.

===== Module L: Interpretation of Key Indicators =====

Key Indicators Closely Related to Success Rate

Indicator	Reference Range	Relationship with Success Rate
AMH	> 1.2 ng/mL	Reflects ovarian reserve. When AMH < 0.5 ng/mL, the number of eggs retrieved is usually ≤3, requiring assessment of suitability for using own eggs.
FSH	< 10 IU/L	FSH > 12 IU/L suggests diminished ovarian response, potentially requiring a high starting dose or a mild stimulation protocol.
Antral Follicle Count (AFC)	7–15	When AFC < 5, the number of eggs retrieved is limited, and an embryo accumulation strategy should be considered.
Vitamin D	≥ 30 ng/mL	Levels below 30 ng/mL are associated with a lower implantation rate; supplementation before transfer is recommended.
TSH	0.5–2.5 mIU/L	> 2.5 mIU/L requires endocrine intervention to reduce the risk of miscarriage.
Semen DFI	< 25%	When DFI > 30%, the blastocyst formation rate decreases; improvement or use of testicular sperm is recommended.

===== Module Q: Frequently Asked Questions =====

Top 5 Questions Patients Ask Most Often

1. "How many people succeed on the first IVF attempt at Peking University Third Hospital?"——About 60%–70% of women under 35 achieve a live birth after the first or second transfer; women over 40 may need more cycles.
2. "Can I still do IVF with low AMH?"——Yes, but it is necessary to assess suitability for using own eggs. When AMH < 0.5 ng/mL, PGT-A to screen for euploid embryos, or considering egg donation, is recommended.
3. "Do I need bed rest after the transfer?"——No. Normal activities do not affect implantation. Prolonged bed rest actually increases the risk of thrombosis and psychological stress.
4. "How long should I prepare before IVF?"——Generally, 1–3 months in advance to adjust diet, weight, supplement folic acid and vitamin D, quit smoking and alcohol, and control metabolic diseases.
5. "What is the cost of IVF at Peking University Third Hospital?"——A routine cycle (excluding PGT) costs about 30,000–50,000 RMB. PGT adds 15,000–30,000 RMB. Medication and testing costs vary significantly between individuals.

===== Module I: Actual Process =====

IVF Medical Process and Schedule at Peking University Third Hospital

• Step 1: Initial Consultation and Assessment (1–2 days)——Basic tests for both partners: AMH, FSH, LH, antral follicle count, semen analysis, karyotype, infectious disease screening.
• Step 2: Protocol Formulation (results within 1 week)——Choose a long protocol, antagonist protocol, mild stimulation protocol, or natural cycle based on ovarian reserve and etiology.
• Step 3: Ovarian Stimulation (10–14 days)——Daily injections of gonadotropins, monitoring follicle development, adjusting dosage.
• Step 4: Egg Retrieval Surgery (30 minutes, intravenous anesthesia)——Observe for 1–2 hours post-surgery before discharge.
• Step 5: Embryo Culture (3–6 days)——Fresh embryo transfer on day 3 or day 5–6; frozen embryos require waiting 1–2 menstrual cycles.
• Step 6: Embryo Transfer (5–10 minutes)——Blood test for HCG 12–14 days post-transfer to determine pregnancy.

A complete fresh embryo transfer cycle from starting the cycle to transfer takes about 4–6 weeks. A frozen embryo cycle requires an additional 1–2 months. A PGT cycle requires waiting for embryo biopsy and screening results, adding 2–4 weeks.
