For families who dream of choosing the gender of their next child—whether for personal reasons, medical considerations, or family balancing—MicroSort® offers a scientifically validated, highly precise method of sperm sorting that can significantly increase the chances of conceiving a boy or a girl. As the only clinically proven sperm-sorting technique of its kind, MicroSort® gives parents more control and clarity in their path to conception.

With the guidance of fertility expert Dr. Nastaran Foyouzi, families have access to this advanced technology alongside world-class reproductive care.

What Is MicroSort® Gender Selection?

MicroSort® is a preconception technique that separates sperm based on whether they carry an X chromosome (which results in a girl) or a Y chromosome (which results in a boy). Normally, semen contains an even 50/50 mix. But with MicroSort®, sperm carrying the desired chromosome can be enriched into a separate sample—giving you the highest level of control currently available in reproductive medicine.

This allows parents to pursue pregnancy with a sperm sample purposely enriched for the gender they hope to conceive.

The Science Behind MicroSort®

MicroSort® is precise because it measures the exact amount of DNA inside each sperm cell.

• X-chromosome sperm (girls) contain 2.8% more DNA
• Y-chromosome sperm (boys) contain slightly less DNA

This small difference is enough for MicroSort® technology to detect and distinguish them accurately.

How MicroSort® Safely Separates Sperm

The MicroSort® process uses a specialized method called flow cytometry to analyze sperm cells one at a time.

Here’s how it works:

1. Sample Preparation

The sperm sample is washed to remove seminal fluid and non-moving sperm cells.

2. DNA Fluorescent Staining

A temporary fluorescent dye is applied to DNA inside each sperm cell.
This allows X- and Y-bearing sperm to glow at different intensities.

3. Laser Analysis

The sperm pass through a focused laser beam inside the flow cytometer:

• X-chromosome sperm glow brighter
• Y-chromosome sperm glow less intensely

4. Computer Sorting

Sophisticated software detects the fluorescence pattern matching the desired gender and separates those sperm into a new, enriched sample.

The result? A highly purified sperm sample that can be used for gender-selective conception with greater confidence and accuracy.

Advanced Compatibility With Multiple Fertility Treatments

The Microsorted sperm sample can be used with several assisted reproductive technologies, including:

• IVF (In Vitro Fertilization)
• ICSI (Intracytoplasmic Sperm Injection)
• PGT (Preimplantation Genetic Testing)

These methods ensure that only one sperm fertilizes the egg—ideal for gender selection.

MicroSort® Laboratories works directly with clinics and specialists around the world, including Dr. Foyouzi, to support patients in achieving their family-building goals.

**Are You a Candidate for MicroSort®?

Here Are the Tests You’ll Need**

Before starting the MicroSort® process, two simple tests are required a few days prior to your sorting procedure. These help determine if sperm sorting is safe, effective, and tailored to your needs.

1. Semen Analysis

A semen analysis determines if the sperm count and motility are strong enough for sorting.

Requirements:

• Collect the sample after 72 hours of abstinence
• The lab evaluates sperm count, movement, and progression

If the results are not optimal, Dr. Foyouzi will discuss alternative options that may still help you achieve your goals.

2. Blood Screening

A standard blood test checks for:

• HIV
• HTLV
• Hepatitis B & C
• CMV
• Syphilis
• Chlamydia/Gonorrhea

MicroSort® cannot accept samples that test positive for certain infections, so this screening ensures safety for both the patient and the lab.

How Effective Is MicroSort®?

Data from partnering fertility clinics shows strong early-stage embryo development:

• 71.4% fertilization rate
• 91.6% cleavage rate

These results demonstrate that MicroSort®–sorted samples perform extremely well during IVF and ICSI, supporting strong embryo growth and increasing the potential for pregnancy success.
