Summary
Elective single embryo transfer (eSET) minimizes multiple pregnancies from in vitro fertilization (IVF) without reducing success rates. This strategy reduces health risks and costs associated with twins, though individual patient factors require consideration.
Area of Science:
- Reproductive Medicine
- Public Health
- Health Economics
Background:
- Assisted reproduction technologies, particularly in vitro fertilization (IVF), have led to an increased incidence of multiple pregnancies.
- Multiple pregnancies, including twins, are associated with significant adverse health outcomes for neonates, mothers, and families, alongside substantial financial burdens on healthcare systems.
Purpose of the Study:
- To evaluate the effectiveness and implications of implementing an elective single embryo transfer (eSET) policy to reduce multiple pregnancies resulting from IVF.
- To identify key factors influencing the successful adoption of eSET and discuss considerations for individual patient cases.
Main Methods:
- Review of strategies to minimize twin pregnancies in IVF, focusing on the practice of transferring a single embryo.
- Analysis of factors critical for the success of eSET, including embryo selection, cryopreservation, and healthcare funding.
Main Results:
- Elective single embryo transfer (eSET) is an effective strategy for reducing the rate of twin pregnancies following IVF.
- eSET can minimize risks and financial costs without compromising overall IVF success rates.
- Individualized assessment is crucial, as transferring two embryos may be more cost-effective in specific situations, such as for older women.
Conclusions:
- The adoption of an eSET policy is a viable approach to mitigate the risks and costs associated with IVF-induced multiple pregnancies.
- Successful implementation of eSET requires improvements in embryo selection, cryopreservation, adequate state funding, and continuous education for all stakeholders.
- A nuanced approach, considering individual patient circumstances, is essential for optimizing the benefits of eSET.

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.

Infertility in Females
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.

Infertility in Males
Male infertility affects millions of couples worldwide, arising from various factors that impact different stages of the reproductive process. An endocrine imbalance resulting from conditions like hypogonadism, Klinefelter syndrome, or pituitary disorders can disrupt hormone levels and reduce sperm production. Testicular defects, such as tumors, cryptorchidism, atrophic testes, abnormal sperm morphology, and low sperm count or motility, may arise due to genetic factors, structural...
Reproductive Cloning
Reproductive cloning is the process of producing a genetically identical copy—a clone—of an entire organism. While clones can be produced by splitting an early embryo—similar to what happens naturally with identical twins—cloning of adult animals is usually done by a process called somatic cell nuclear transfer (SCNT).
Somatic Cell Nuclear Transfer
In SCNT, an egg cell is taken from an animal and its nucleus is removed, creating an enucleated egg. Then a somatic cell—any cell that is not a sex...

Intrauterine Drug Delivery Systems
Controlled-release systems for intravaginal and intrauterine drug delivery have been developed primarily for the administration of contraceptive steroid hormones. These delivery routes circumvent first-pass hepatic metabolism, thereby enhancing bioavailability and allowing for reduced systemic dosages compared to oral administration. Such approaches contribute to improved therapeutic efficacy and patient compliance, particularly in long-term contraceptive regimens.Intravaginal Drug Delivery...
