How ICSI help with Male Infertility?
Intracytoplasmic sperm injection (ICSI treatment) involves injection of a single sperm into an egg in order to cause fertilisation. The steps involved are the same as for IVF, except that in the laboratory, a single sperm is picked up with a fine needle and injected directly into the egg.
Just as IVF changed the destiny of women with damaged tubes, ICSI (Intracytoplasmic sperm injection) is another fertility treatment which has revolutionised the treatment of male infertility. Without it, millions of men with poor or weak sperm would never be able to father babies. With male infertility increasing worldwide, more and more couples are having to resort to ICSI treatment to have children.
At KL Fertility Centre, this precision technique is performed within an RTAC-accredited environment, combining more than 25 years of expertise with advanced laboratory standards. For many patients, ICSI is not just a procedure. It is the breakthrough that turns possibility into parenthood.
Who Benefits from ICSI?
ICSI is specifically recommended when natural fertilisation or standard IVF is unlikely to be successful. Your fertility specialist will assess your individual situation and advise whether ICSI is appropriate for your case.
Male Factor Infertility
- Very low sperm count (oligozoospermia)
- Poor sperm motility (asthenozoospermia)
- Abnormal sperm morphology (teratozoospermia)
- Zero sperm in ejaculate (azoospermia) — requiring surgical sperm retrieval
- Previous vasectomy where sperm retrieval is needed
- High levels of sperm DNA fragmentation
Other Clinical Indications
- Previous IVF cycles with low or failed fertilisation
- Low number of eggs retrieved (where every egg must be maximised)
- Use of frozen or surgically retrieved sperm
- Unexplained infertility where standard IVF has not succeeded
- Preimplantation Genetic Testing (PGT) planned, requiring confirmed fertilisation
ICSI with Surgical Sperm Retrieval
For men with no sperm in their ejaculate (azoospermia), whether due to a blockage, a previous vasectomy, or a production problem, sperm can often be retrieved surgically and used for ICSI. KL Fertility Centre offers the following surgical sperm retrieval techniques:
PESA
Percutaneous Epididymal Sperm Aspiration. Sperm is aspirated from the epididymis using a fine needle. Suitable for men with obstructive azoospermia (e.g., vasectomy or blocked ducts).
TESA
Testicular Sperm Aspiration. Sperm is extracted directly from testicular tissue using a needle. Used when epididymal sperm retrieval is not possible.
MicroTESE
Microsurgical Testicular Sperm Extraction. A microsurgical technique to locate and retrieve sperm from men with non-obstructive azoospermia where conventional retrieval may fail.
Advanced Sperm Selection
Microfluidic Sperm Sorting
KL Fertility Centre offers microfluidic sperm sorting, an advanced sperm preparation technique that selects the highest-quality sperm by guiding them through microscopic channels designed to replicate the natural environment of the female reproductive tract.
Unlike conventional sperm preparation methods, microfluidic sorting selects sperm based on motility and membrane integrity without centrifugation, reducing DNA fragmentation and oxidative stress. This results in a sperm sample with higher motility, intact membrane integrity, and reduced DNA fragmentation, which may improve fertilisation rates and embryo quality, hence improving chances of IVF or ICSI success. Microfluidic sperm sorting is particularly beneficial for couples with male factor infertility, high sperm DNA fragmentation, or previous failed ICSI cycles.
The ICSI Process at KL Fertility Centre
An ICSI cycle at KL Fertility Centre follows the same clinical pathway as IVF, with the addition of the microinjection step in the laboratory:
Initial Fertility Assessment
Both partners undergo a full evaluation: semen analysis and, where indicated, sperm DNA fragmentation testing for the male partner; ovarian reserve assessment (AMH, antral follicle count), hormonal profile, and pelvic ultrasound for the female partner.
Ovarian Stimulation
The female partner receives hormone injections for around 10 to 12 days, depending on ovarian response, to stimulate the ovaries to produce multiple mature eggs. Dosage is individualized based on age, ovarian reserve, and treatment response.
Cycle Monitoring
Regular ultrasound scans and blood tests track follicle development. When follicles reach the target size, a trigger injection is administered to time the final maturation of the eggs before retrieval.
Egg Retrieval (OPU)
Eggs are collected in a minor procedure (Ovum Pick-Up) performed under sedation or light anaesthesia. A fine needle guided by ultrasound is used to aspirate eggs from the follicles. The procedure typically takes 15 to 30 minutes.
Sperm Collection or Surgical Retrieval
The male partner provides a semen sample on the day of egg retrieval. For men with azoospermia, sperm is retrieved surgically (PESA, TESA, or MicroTESE). The sample is prepared in the laboratory so a suitable sperm can be selected for injection.
ICSI — Sperm Injection
A single carefully selected sperm is injected directly into the cytoplasm of each mature egg using a fine glass needle under high-powered microscopy. This step is performed by a specialist embryologist in the embryology laboratory.
Embryo Culture
Fertilised eggs are cultured in the laboratory for several days. Depending on embryo development and the patient’s treatment plan, embryos may be transferred at the cleavage stage or blastocyst stage. Blastocyst-stage embryos are often preferred when suitable embryos are available. The embryologist will advise on the number and quality of embryos available.
Embryo Transfer & Pregnancy Test
One or two suitable embryos are transferred into the uterus using a thin catheter. Surplus good-quality embryos may be frozen for future use through vitrification. A blood pregnancy test, commonly beta-hCG, is usually performed around 10 to 14 days after the transfer.
ICSI Success Rates
Intracytoplasmic Sperm Injection (ICSI) has become one of the most successful techniques in modern IVF, particularly for couples facing severe male infertility or previous fertilisation failure. By directly injecting a single sperm into the egg, ICSI achieves fertilisation rates of over 70 to 80%.
At KL Fertility Centre in Kuala Lumpur, ICSI is performed within our RTAC-accredited laboratory, where more than 25 years of clinical expertise meets advanced laboratory technology.

FAQs
ICSI (Intracytoplasmic Sperm Injection) is a specialised form of IVF where a single sperm is injected directly into each egg by a specialist embryologist, rather than relying on the sperm to penetrate the egg naturally.
The overall clinical process, ovarian stimulation, egg retrieval, embryo culture, and embryo transfer, is the same as standard IVF. The key difference is in the laboratory: ICSI is used when sperm quality is too poor for natural fertilisation to occur reliably.
ICSI is recommended when there is severe male factor infertility, including very low sperm count, poor motility, or abnormal morphology. It is also indicated for men with no sperm in their ejaculate (azoospermia) who require surgical sperm retrieval, couples who have had previous failed or low fertilisation in a standard IVF cycle, cases where very few eggs are retrieved, and when frozen or surgically retrieved sperm is being used.
ICSI success rates vary depending on factors such as the female partner’s age, egg quality, sperm quality, and embryo development. For detailed statistics and outcomes, please refer to our IVF Success Rates page. Your specialist will also advise on your individual prognosis at your initial consultation.
The cost of an ICSI cycle varies depending on your individual fertility profile, medication requirements, and whether additional procedures such as surgical sperm retrieval or embryo freezing are needed. Contact our team for a personalised cost estimate based on your specific protocol.
The ICSI microinjection itself is performed in the laboratory on the retrieved eggs and is not felt by the patient. The procedure that may cause discomfort is the egg retrieval (OPU), which is performed under sedation or light anaesthesia.
Most patients experience mild bloating or pelvic discomfort during the stimulation phase, and some cramping after egg retrieval, which typically resolves within a day or two. The embryo transfer step is generally painless and requires no anaesthesia.
ICSI is a fertilisation technique performed as part of an IVF cycle, so the overall treatment duration is the same as a standard IVF cycle, typically 4 to 6 weeks from the start of ovarian stimulation to embryo transfer. If a frozen embryo transfer (FET) is planned rather than a fresh transfer, the timeline extends by an additional cycle preparation period. Your specialist will provide a more precise timeline based on your individual protocol.
Yes. For men with azoospermia, where there is no sperm in the ejaculate, sperm may be retrieved surgically from the epididymis or testes. Techniques may include PESA (Percutaneous Epididymal Sperm Aspiration), TESA (Testicular Sperm Aspiration), and MicroTESE (Microsurgical Testicular Sperm Extraction).
If suitable sperm is retrieved, it can then be used for ICSI. Whether sperm can be successfully retrieved depends on the cause of azoospermia. Your specialist will assess this before recommending a surgical sperm retrieval procedure.
Good-quality embryos that are not transferred in the current cycle may be frozen through vitrification and stored for future use by the couple. Frozen embryo transfer (FET) cycles are usually less physically demanding than a full stimulation cycle because they do not require another egg retrieval.
Your embryologist will advise on the number and quality of embryos suitable for freezing after your ICSI cycle. Under current Malaysian medical guidelines, embryo donation is generally not permitted. Couples should discuss embryo storage, future use, storage duration, and consent requirements directly with their fertility specialist.
ICSI carries similar risks to standard IVF. These may include ovarian hyperstimulation syndrome (OHSS) during the stimulation phase, a small risk of complications from egg retrieval or sedation, and a higher chance of multiple pregnancy if more than one embryo is transferred.
There is also a possibility that some eggs may not fertilise, or that embryos may not develop to a suitable stage for transfer. Your specialist will review these risks based on your medical history, ovarian reserve, treatment response, and embryo transfer plan before treatment begins.
ICSI does not allow parents to choose whether they will have a boy or a girl. While some studies suggest assisted reproductive techniques may have small effects on birth sex ratios, ICSI is not used as a reliable method for selecting a baby’s sex. The sex of a baby depends on whether the fertilising sperm carries an X or Y chromosome.
If there is a specific medical reason related to serious sex-linked genetic conditions, Preimplantation Genetic Testing (PGT) may be discussed with your fertility specialist.
