ICSI vs Standard Insemination in IVF: When to Choose Which

Understanding ICSI vs Standard Insemination

For many individuals and couples pursuing parenthood through fertility treatment in California, understanding the difference between ICSI and standard insemination in IVF is essential for making an informed choice. Both methods take place within the same IVF cycle but differ in how the sperm and egg interact in the laboratory.

At the Fertility Institute of San Diego, led by double board-certified Reproductive Endocrinologist Dr. Minoos Hosseinzadeh, every treatment plan is customized. “Every couple’s fertility story is unique. That is why we take the time to determine which approach provides the strongest chance for successful fertilization based on each patient’s reproductive history,” explains Dr. Hosseinzadeh.

What Is IVF?

In Vitro Fertilization (IVF) involves stimulating the ovaries to produce mature eggs, retrieving those eggs, and fertilizing them in a controlled laboratory environment. Embryos develop until they reach the blastocyst stage, at which time they are transferred into the uterus or frozen for later use.

IVF is widely used for blocked fallopian tubes, ovulation disorders, or unexplained infertility. With advancements in embryo monitoring systems and laboratory processes, IVF success rates in San Diego have continued to improve.

What Is Standard Insemination?

In standard insemination, eggs and sperm are placed together in a culture dish, allowing the sperm to penetrate the egg naturally. This approach closely mirrors the fertilization process in the body and is often recommended when sperm parameters are within the normal range.

What Is ICSI?

Intracytoplasmic Sperm Injection, commonly known as ICSI, is a micromanipulation technique in which a single sperm is selected and injected directly into an egg using a microscopic needle. This method is especially beneficial for patients undergoing male infertility treatment in California who have a low sperm count, poor motility, or abnormal morphology of the sperm head.

“ICSI revolutionized assisted reproductive technology by giving couples strong fertilization potential even when standard insemination might not succeed,” says Dr. Hosseinzadeh. “It enables us to bypass natural barriers and achieve excellent outcomes when sperm parameters are compromised.”

When to Choose ICSI Over Standard Insemination

ICSI is recommended when:

• Sperm count is low
• Sperm motility is reduced
• Sperm morphology is abnormal
• Previous IVF cycles resulted in failed fertilization
• Previously frozen eggs or sperm are used
• Genetic testing of embryos is planned

For patients with normal sperm parameters and no fertilization concerns, standard insemination often remains the preferred first step.

Cost of ICSI and IVF in California

ICSI adds an additional $1,500 to $2,500 to your basic IVF cycle charge. This reflects the advanced laboratory technology and specialized embryologist expertise required.

Dr. Hosseinzadeh encourages patients to view treatment as a long-term investment. “When considering costs, focus on the ultimate goal: a healthy pregnancy and baby. What matters most is the precision and experience behind the process,” she explains.

ICSI Procedure Step by Step

1. Ovarian Stimulation
2. Egg Retrieval
3. Sperm Selection
4. Microscopic Injection into the Egg
5. Embryo culture to the blastocyst or day 5 stage
6. Embryo Transfer, Embryo Biopsy for Preimplantation Genetic Testing (PGT) or Embryo Cryopreservation
