Human rights to in vitro fertilization

International Journal of Gynecology and Obstetrics, 2013
AbstractThe Inter‐American Court of Human Rights (the Court) has ruled that the Supreme Court of Costa Rica's judgment in 2000 prohibiting in vitro fertilization (IVF) violated the human right to private and family life, the human right to found and raise a family, and the human right to non‐discrimination on grounds of disability, financial means, or ...

Simulated microgravity alters sperm navigation, fertilization and embryo development in mammals [PDF]

Communications Biology
As human space exploration extends toward long-duration missions and off-Earth settlements, understanding the impact of microgravity on reproduction is vital for sustaining life beyond Earth.

CD9 Expression by Human Granulosa Cells and Platelets as a Predictor of Fertilization Success during IVF

Obstetrics and Gynecology International, 2010
Objective. To determine whether CD9 expression on human granulosa cells (GCs) and platelets could predict the success of conventional fertilization of human oocytes during in vitro fertilization (IVF). Methods.

MAIA, Fc receptor-like 3, supersedes JUNO as IZUMO1 receptor during human fertilization. [PDF]

Sci Adv, 2022
Gamete fusion is a critical event of mammalian fertilization. A random one-bead one-compound combinatorial peptide library represented synthetic human egg mimics and identified a previously unidentified ligand as Fc receptor-like 3, named MAIA after the ...

Association of the Serum Folate and Total Calcium and Magnesium Levels Before Ovarian Stimulation With Outcomes of Fresh In Vitro Fertilization Cycles in Normogonadotropic Women

Frontiers in Endocrinology, 2022
BackgroundWomen of reproductive age are recommended to consume folic acid and other supplements before conception and during pregnancy. We aimed to investigate the association of the serum folate and total magnesium (Mg) and calcium (Ca) levels before ...

Spermatogenic cell-specific SPACA4 is essential for efficient sperm-zona pellucida binding in vitro

Frontiers in Cell and Developmental Biology, 2023
Fertilization is a complex and highly regulated process that involves a series of molecular interactions between sperm and oocytes. However, the mechanisms of proteins involved in human fertilization, such as that of testis-specific SPACA4, remain poorly

Gene mutations associated with fertilization failure after in vitro fertilization/intracytoplasmic sperm injection

Frontiers in Endocrinology, 2022
Fertilization failure during assisted reproductive technologies (ART) is often unpredictable, as this failure is encountered only after in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) have been performed.

The role of spermatozoa-zona pellucida interaction in selecting fertilization-competent spermatozoa in humans

Frontiers in Endocrinology, 2023
Human fertilization begins when a capacitated spermatozoon binds to the zona pellucida (ZP) surrounding a mature oocyte. Defective spermatozoa-ZP interaction contributes to male infertility and is a leading cause of reduced fertilization rates in ...

Identification of Novel Mutations in CDC20: Expanding the Mutational Spectrum for Female Infertility

Frontiers in Cell and Developmental Biology, 2021
Oocyte maturation and fertilization are fundamental processes for successful human reproduction, and abnormalities in these processes will cause infertility.

Identification of Sialyl-Lewis(x)-Interacting Protein on Human Spermatozoa

Frontiers in Cell and Developmental Biology, 2021
Capacitated spermatozoa initiate fertilization by binding to the zona pellucida (ZP). Defective spermatozoa-ZP binding causes infertility. The sialyl-Lewis(x) (SLeX) sequence is the most abundant terminal sequence on the glycans of human ZP glycoproteins
