ICSI is a specialised form of IVF recommended primarily for male-factor infertility. SheIVF lists 1 verified ICSI specialists in Kolkata — with confirmed credentials, experience details, and transparent fees — so you can compare and connect directly.
ICSI, or Intracytoplasmic Sperm Injection, is an advanced IVF technique in which a single sperm is injected directly into a mature egg using a fine glass needle. Unlike conventional IVF where sperm and egg are placed together and fertilisation happens naturally, ICSI bypasses the natural fertilisation process entirely. It is the standard of care for severe male-factor infertility and is widely performed at fertility clinics in Kolkata.
ICSI is recommended when the sperm count is very low, sperm motility or morphology is severely affected, the sperm cannot penetrate the egg naturally, previous IVF cycles have had poor or failed fertilisation, or sperm is retrieved surgically through TESA or PESA. It is also used with frozen sperm or donor sperm in some cases. Your fertility specialist in Kolkata will advise whether ICSI or conventional IVF fertilisation is more appropriate for your diagnosis.
ICSI is performed as part of an IVF cycle. The steps are identical up to egg retrieval. After eggs are collected, the embryologist selects a single healthy sperm and injects it directly into each mature egg using a micromanipulation needle. Fertilisation is confirmed the following day. Resulting embryos are cultured for 3 to 5 days before the best quality embryo is transferred into the uterus. A pregnancy test is done approximately 14 days after transfer.
ICSI fertilisation rates — meaning the percentage of injected eggs that fertilise successfully — range from 70 to 80 percent. However, overall IVF-ICSI pregnancy rates depend on factors beyond fertilisation, including embryo quality, uterine receptivity, and the woman's age. In India, IVF-ICSI success rates for women under 35 range from 40 to 60 percent per transfer. Ask your specialist in Kolkata for clinic-specific data.
ICSI is performed as part of an IVF cycle, so the cost reflects a full IVF cycle plus the ICSI procedure. Costs in Kolkata vary by clinic and whether additional procedures like embryo freezing or genetic testing are included. Indicative consultation fees for ICSI specialists in Kolkata are listed on each doctor profile on SheIVF.
When choosing an ICSI specialist in Kolkata, prioritise clinics with an experienced embryology team and a well-equipped IVF laboratory — the quality of the lab directly affects ICSI outcomes. Check the doctor's experience with male-factor infertility cases specifically. Review consultation fees and patient ratings on SheIVF before booking.
ICSI carries the same risks as a standard IVF cycle — mild OHSS, multiple pregnancy risk if more than one embryo is transferred, and a small procedural risk to eggs during injection (approximately 5 to 10 percent of eggs may not survive the microinjection). These risks should be discussed openly with your specialist in Kolkata before proceeding.

In conventional IVF, eggs and sperm are placed together in a dish and fertilisation happens naturally. In ICSI, a single sperm is injected directly into each egg. ICSI is recommended for male-factor infertility or poor fertilisation in previous IVF cycles.
