In Vitro Fertilization01:24

In Vitro Fertilization

820
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...

Infertility in Females

3.6K
Female infertility is defined as the inability to conceive after a year of regular, unprotected intercourse and affects about 10–15% of couples worldwide. The primary cause of female infertility is ovulatory disorders, which hinder the release of eggs. These disorders can be classified as hypothalamic amenorrhea, polycystic ovarian syndrome (PCOS), premature ovarian failure, and hyperprolactinemic anovulation disorders.
Endometriosis, a condition characterized by abnormal growth of...

Summary
This summary is machine-generated.

Clinical embryologists globally discard supernumerary in vitro fertilization (IVF) embryos using varied methods. Most embryologists agree on the need for a standardized, universally accepted protocol for embryo disposal practices.

Area of Science:

  • Reproductive Medicine
  • Clinical Embryology
  • In Vitro Fertilization (IVF)

Background:

  • Supernumerary embryos are a common outcome of in vitro fertilization (IVF) procedures.
  • Current practices for discarding these embryos lack global standardization.

Purpose of the Study:

  • To report on the global practices and trends in discarding supernumerary embryos.
  • To understand the current landscape of clinical embryologists' approaches to embryo disposal.

Main Methods:

  • A web-based, anonymous questionnaire was distributed globally to practicing clinical embryologists.
  • Data was collected over 8 months from 65 countries.

Main Results:

  • The majority of practitioners dispose of embryos in dedicated trash receptacles.
  • Most discard embryos separately and often wait until day 6, with many procedures being witnessed.
  • A significant majority (59.5%) believe a universally accepted protocol would benefit the practice.

Conclusions:

  • This study offers unique insights into diverse global embryo disposal practices.
  • There is a significant divergence in reported practices, highlighting the need for standardization.
  • Embryologists recognize and advocate for the implementation of a universally accepted protocol.
