Offering the Syringe Method as an Option for Couples' Fertility Journey

  • 01 What is the Syringe Method?

    Start Without Pressure! A "Self-Fertility Method" You Can Do at Home

    The syringe method is a home-based fertility approach developed by our company, incorporating feedback from fertility specialists and patients. It utilizes our syringe method kit, inspired by techniques such as the "dropper method," "intravaginal insemination," "self-AIH," and "self-injection AIH."

    02 How to Increase Pregnancy Success Rate

    Time Intercourse Within 5 Days:
    2 Days Before and 2 Days After Estimated Ovulation

    Pregnancy success is highest 2 days before ovulation! Since it's difficult to pinpoint the exact ovulation date, the ideal approach is to time intercourse multiple times during a 5-day window: 2 days before to 2 days after your estimated ovulation date.

    03 Today's Fertility Landscape

    Many Face Emotional Burden and Time Constraints

    Many couples experience emotional pressure and time constraints when trying to time intercourse. With diverse lifestyles today, more couples struggle with timing issues or find their fertility journey isn't progressing as planned.

    04 Why Choose the Syringe Method?

    Many Use It to Solve Timing Issues

    We've found that many couples use or want to use the syringe method to address timing-related challenges. Many also want to try it casually before pursuing clinic-based fertility treatments.

    05 Cost of Fertility Treatment

    The Syringe Method Costs Just $10 USD per Use

    In-vitro fertilization typically costs $3,000-$5,000 per cycle, and artificial insemination costs around $150 per cycle. In contrast, the syringe method costs only approximately $10 USD per use.* * Based on the cost per use of the Prement Syringe Ring 7-pack (with 25% discount applied).

SUPERVISING DOCTOR

IVF Eita Clinic
Dr. Mayu Eita

Graduated from Fujita Health University School of Medicine in 2012
Certified Obstetrician-Gynecologist by the Japan Society of Obstetrics and Gynecology

At around age 20, I was diagnosed with polycystic ovary syndrome, adenomyosis, endometriosis, and bilateral ovarian tumors. When I saw the ultrasound image showing my uterus was tilted backward, I was still unmarried but worried I might not be able to have children. Fortunately, I met a physician who recommended endometriosis treatment. After undergoing long-term treatment, I was blessed with two children through natural conception. I believe many of my patients at the clinic have similar conditions. As someone who has experienced these challenges, I can empathize with my patients and share the importance of treatment. Please feel free to discuss any concerns with me. I'm committed to providing support beyond clinical care.
