After a Semen Report Showing "No Sperm"

In the outpatient clinic, a 32-year-old man looks anxious, holding a semen analysis report showing no sperm after three rounds of centrifugation. His hormone levels: FSH 8.2 mIU/mL, LH 4.5 mIU/mL, testosterone normal. Palpation reveals bilateral full epididymides and palpable vas deferens. Preliminary assessment: high probability of obstructive azoospermia.

At this point, the patient's core questions are: How good is Hong Kong TESE/ICSI technology? Can I have a child using my own sperm? This article does not discuss success rates but focuses on the medical logic and actual process, outlining the decision-making path and preparation details.

Module A: Direct Answer

Core Conclusion on Hong Kong TESE/ICSI Technology

TESE (Testicular Sperm Extraction) is a minimally invasive procedure to obtain sperm from the testicles, and ICSI (Intracytoplasmic Sperm Injection) involves injecting a single sperm directly into an egg for fertilization. Combining both can provide genetic offspring for most azoospermic patients (especially those with obstructive azoospermia). Hong Kong's fertility centers are on par with Europe and the US in microdissection TESE (micro-TESE) and ICSI technology, possessing mature laboratory cryopreservation systems, but the specific plan requires individualized assessment.

Module B: Why This Issue Arises

Why is TESE+ICSI Necessary?

Azoospermia accounts for about 10%-15% of male infertility. The causes fall into two main categories:

• Obstructive Azoospermia: Sperm production is normal, but the reproductive ducts (e.g., epididymis, vas deferens) are blocked. TESE can easily retrieve sperm from the testicles or epididymis.
• Non-obstructive Azoospermia: Testicular spermatogenesis failure or severe impairment. In this case, microdissection TESE is needed, using an operating microscope to find focal areas of spermatogenesis. About 50% of men with non-obstructive azoospermia can have sperm found via micro-TESE.

ICSI is necessary because testicular sperm are often not fully mature and have poor motility, making natural fertilization impossible. Sperm must be injected directly into the egg cytoplasm via ICSI.

Module C: Doctor's Perspective Module G: Most Easily Overlooked Details

4 Most Easily Overlooked Details

1. Preoperative Infection Screening is Essential: Hong Kong requires tests for HIV, Hepatitis B, Hepatitis C, Syphilis, etc., with results valid for 6 months. Positive results require special handling of sperm cryopreservation media.
2. Sperm Cryopreservation Survival Rate: Post-thaw viability of testicular sperm typically decreases by 10%-20%. If very few sperm are retrieved, synchronizing sperm retrieval with a fresh egg cycle is recommended.
3. Female Age Affects the Entire Outcome: Even if sperm are found via TESE, if the female partner has poor ovarian reserve (AMH < 1.0 ng/mL), few eggs may be retrieved, potentially leading to no embryos for transfer.
4. Genetic Counseling is a Prerequisite: Men with Y-chromosome AZFc deletions have a high probability of sperm retrieval via TESE, but any male offspring will inherit the same deletion. Preimplantation Genetic Testing (PGT) or donor sperm options need to be discussed in advance.

Module H: Common Pitfalls

3 Common Cognitive Misconceptions to Avoid

• "If you have testicles, sperm can definitely be found": In non-obstructive azoospermia, 40%-50% of men still cannot have sperm found via microdissection TESE. Preoperative assessment is important but cannot guarantee 100% success.
• "Once TESE is done, IVF will succeed": TESE only solves the sperm problem. Embryo implantation depends on embryo quality, endometrial receptivity, chromosomal euploidy, and other factors.
• "Choosing the cheapest Hong Kong hospital saves money": TESE/ICSI requires extremely high laboratory standards. Low cost may indicate insufficient experience in microdissection TESE or unstable culture systems, leading to low fertilization rates.

Module I: Actual Process

Actual Process of Hong Kong TESE/ICSI

Step 1: Comprehensive Examination and Evaluation (approx. 1-2 weeks)

Examination Item	Purpose
Semen Analysis (≥2 times)	Confirm type of azoospermia
Sex Hormone Panel (FSH, LH, T, PRL, E2, SHBG)	Assess testicular spermatogenic function
Karyotype, Y-chromosome microdeletion	Rule out genetic causes, guide treatment plan
Reproductive System Ultrasound (testes, epididymides, vas deferens)	Determine obstruction location and testicular volume
Infectious Disease Screening	Laboratory safety and cryopreservation compliance

Step 2: Decide Sperm Retrieval Path and Start Cycle

• If obstructive: Arrange epididymal aspiration (PESA) or TESE. Usually, sperm retrieval is synchronized with the female partner's egg retrieval day.
• If non-obstructive: Recommend micro-TESE. Some Hong Kong centers perform a diagnostic biopsy first to assess spermatogenic status before deciding to proceed with a cycle.

Step 3: Sperm Retrieval Surgery (approx. 30-60 minutes)

Local anesthesia or intravenous sedation. A small scrotal incision is made to expose testicular tissue, and a small amount of seminiferous tubules is removed. Transparent, plump seminiferous tubules are identified under a dissecting microscope, and an embryologist isolates sperm in the lab under a microscope. Retrieved sperm are immediately frozen or used directly for ICSI.

Step 4: ICSI and Embryo Culture

ICSI is performed 4-6 hours after the female partner's egg retrieval. Fertilization is checked post-injection, and embryos are cultured to the blastocyst stage (day 5-6). PGT (chromosomal screening) is optional to reduce genetic risks.

Step 5: Transfer and Luteal Support

Typically, 1-2 blastocysts are transferred, and remaining good-quality blastocysts are frozen. A blood test for hCG is done 12-14 days after transfer.

Module K: Cost Factors

Cost Breakdown and Influencing Factors

Item	Estimated Range (HKD)
Female Ovulation Stimulation Medication (imported)	15,000 - 25,000
Egg Retrieval Surgery	20,000 - 30,000
TESE/micro-TESE Surgery	22,000 - 35,000
ICSI Procedure Fee	18,000 - 25,000
Embryo Culture + Cryopreservation	12,000 - 18,000

Total cost typically ranges from HKD 100,000 to 180,000, depending on medication response, surgical complexity, and whether PGT is required. Some Hong Kong centers offer package prices.

Module Q: Frequently Asked Questions

Frequently Asked Questions (from real consultations)

• "Will TESE surgery affect my future testosterone production?" — Removing a small amount of tissue from one testicle has minimal impact on overall endocrine function; most patients experience no significant drop in testosterone postoperatively.
• "If the retrieved sperm quality is poor, can ICSI still achieve fertilization?" — Yes. ICSI has lower requirements for sperm morphology and motility; as long as live sperm are present, injection is possible.
• "If no sperm were found on the first TESE, can a second attempt be made?" — Some centers may try the contralateral testicle or repeat micro-TESE, but success rates decrease with each attempt.
• "Compared to mainland China, does Hong Kong have advantages for TESE/ICSI?" — Hong Kong laboratories often introduced micro-TESE earlier and offer more flexible medication options, but the biggest difference lies in more relaxed policies regarding donor sperm and PGS.

Module D: Age-Related Differences (Naturally Integrated)

Impact of Age on the Treatment Plan

When the female partner is over 38, ovarian response declines, leading to fewer eggs retrieved. If TESE yields only a very small number of sperm (just a few), there is a risk of having sperm but no eggs. It is recommended to assess AMH and antral follicle count in advance. If AMH is < 1.2 ng/mL, consider accumulating eggs or embryos over 1-2 cycles before performing sperm retrieval surgery.

When the male partner is over 45, the DNA fragmentation index in testicular sperm may be higher. Although ICSI bypasses natural selection, the risk of embryonic aneuploidy increases.

Special Situations (Module N)

Management of Special Situations

• Klinefelter Syndrome (47,XXY): About 50% can have sperm retrieved via micro-TESE, but genetic counseling and PGT are necessary beforehand.
• Azoospermia After Cryptorchidism Surgery: There is still a reasonable chance of obtaining sperm after unilateral cryptorchidism surgery; an active attempt is recommended.
• Spinal Cord Injury or Retrograde Ejaculation: Options include sperm extraction from urine or direct TESE.
