Selection pressure for the factor-V-Leiden mutation and embryo implantation
Lancet (London, England)
|October 25, 2001
Summary
The factor-V-Leiden mutation may improve embryo implantation rates, despite its association with thrombosis and pregnancy complications. This finding suggests a potential genetic advantage for successful in-vitro fertilization outcomes.
Area of Science:
- Reproductive Medicine
- Human Genetics
- Thrombophilia
Background:
- The factor-V-Leiden mutation is prevalent in Caucasian populations but linked to adverse pregnancy outcomes like preterm birth and deep-vein thrombosis.
- The evolutionary advantage or reason for its high frequency remains unclear.
Discussion:
- This study utilized in-vitro fertilization (IVF) with intracytoplasmic sperm injection (ICSI) in 102 mother-child pairs as a model to investigate implantation success.
- A significantly higher success rate for the first embryo transfer was observed in mother-child pairs carrying the factor-V-Leiden mutation (90%) compared to those without (49%).
- The median number of unsuccessful transfers was also lower in mutation-positive pairs, indicating improved implantation efficiency.
Key Insights:
- The factor-V-Leiden mutation appears to confer a genetic advantage by enhancing embryo implantation rates during IVF.
- This suggests a potential balancing selection mechanism for the mutation, counteracting its known risks.
Outlook:
- Further research is needed to elucidate the precise biological mechanisms underlying the improved implantation associated with factor-V-Leiden.
- Understanding this genetic advantage could inform strategies for improving IVF success rates in specific patient populations.

01:59CRISPR
Genome editing technologies allow scientists to modify an organism’s DNA via the addition, removal, or rearrangement of genetic material at specific genomic locations. These types of techniques could potentially be used to cure genetic disorders such as hemophilia and sickle cell anemia. One popular and widely used DNA-editing research tool that could lead to safe and effective cures for genetic disorders is the CRISPR-Cas9 system. CRISPR-Cas9 stands for Clustered Regularly Interspaced Short...
01:26Factors Affecting the Risk of Infection
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin create...

01:07Teratogenicity
The ability of a drug to produce structural deformations and functional abnormalities in the developing embryo or the fetus is called teratogenicity, and the drug producing this effect is known as a teratogen. Teratogenic effects include stillbirth, miscarriage, intrauterine growth restriction, and neurocognitive delay. A teratogen may affect the embryo at different stages of development, which is important in determining the type and extent of the damage. During blastocyst formation, the early...
01:24In 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...

01:28Infertility 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.

01:21Intrauterine 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...
