In Vitro Fertilization01:24

In Vitro Fertilization

In vitro fertilization (IVF) is a form of assisted reproductive technology where an egg is fertilized with sperm in a controlled laboratory environment before transferring the resulting embryo into the uterus. This process is designed to help individuals and couples experiencing difficulties conceiving.
The IVF process begins with ovarian stimulation, during which reproductive endocrinologists prescribe hormonal medications to stimulate the ovaries to produce multiple eggs instead of the single...

Summary

Embryo transfer (ET) fluid dynamics show higher stress on embryos with increased injection speed and narrowed catheters. Gentle transfer, minimal speed, and central embryo placement are recommended for better outcomes.

Area of Science:

  • Reproductive medicine
  • Biotechnology
  • Mechanical engineering

Background:

  • Embryo transfer (ET) is a critical step in assisted reproductive technologies.
  • Understanding fluid dynamics during ET is crucial for optimizing success rates.
  • Previous studies have not fully elucidated the impact of injection parameters on embryo stress.

Purpose of the Study:

  • To investigate the fluid dynamics during embryo transfer.
  • To quantify the effects of injection speed and catheter design on shear stress, dynamic pressure, and velocity experienced by the embryo.

Main Methods:

  • Computational fluid dynamics (CFD) simulations were employed.
  • Fluid velocity, dynamic pressure, and shear stress were calculated at various injection speeds (0.1-20 m/sec).
  • The impact of catheter lumen narrowing on fluid dynamics was assessed.

Main Results:

  • Increased injection speed significantly elevated shear stress, dynamic pressure, and velocity differences acting on the embryo.
  • A 20% reduction in catheter lumen diameter amplified fluid velocity by 78%.
  • Embryos near the catheter wall experienced substantially higher stress compared to those centrally located.

Conclusions:

  • Embryo transfer should utilize minimal injection speed to reduce mechanical stress.
  • Catheter lumen narrowing should be avoided to maintain optimal fluid flow.
  • Positioning the embryo centrally, away from the catheter wall, is recommended during transfer.
