Sperm:Oocyte ratios in an in vitro fertilization (IVF) program

Journal of Assisted Reproduction and Genetics, 1994
During the past few years, many oocyte insemination techniques, including microinjection, have evolved in the treatment of male-factor infertility. This preliminary study was designed to evaluate whether microdroplet insemination could be considered a reliable technique, especially for semen samples with male-factor defects.

Microfluidic technology for in vitro fertilization (IVF)

JMST Advances, 2019
With the recent development in science and technology, the advancement in in vitro fertilization to treat infertility has been one of the most revolutionary advances. However, the success rate of the IVF process depends on the efficiency of each step of the process. The physical tools used to enhance the process continue to change.

Predictive factors in in vitro fertilization (IVF)

Human reproduction update, 2010
BACKGROUND: Various models have been developed for the prediction of pregnancy after in vitro fertilization (IVF). These models differ from one another in the predictors they include. We performed a systematic review and meta-analysis to identify the most relevant predictors for success in IVF.METHODS: We systematically searched MEDLINE and EMBASE for ...

In-Vitro Fertilization (IVF) and Gamete Intrafallopian Transfer (GIFT)

Obstetrics and Gynecology Clinics of North America, 1987
In the past decade, the use of in-vitro fertilization and embryo transfer (IVF-ET) procedures as a means of treatment of infertility has become a clinical reality. More recently, similar yet differing techniques have been described that further expand options of treatment of infertile couples. This article summarizes recent advances in IVF and compares

SUPER HUMAN BY IN VITRO FERTILIZATION (IVF)

2023
In the realm of in vitro fertilization (IVF), optimizing embryos involves a meticulous evaluation of diverse environmental strategies proposed in the scientific literature. Researchers scrutinize methodologies targeting improvements in conditions during IVF procedures, including temperature, pH, and nutrient concentrations.

Experience with intravaginal culture for in vitro fertilization (IVF)

Journal of In Vitro Fertilization and Embryo Transfer, 1991
It has been reported that intravaginal culture (IVC) yields results comparable to those obtained with classic IVF techniques; furthermore, it can simplify and reduce the costs of the procedure. In our experience with IVC however, only 8 of 78 mature oocytes inseminated (10.2%) fertilized. Possible causes of this low fertilization rate were analyzed. In

In vitro fertilization (IVF)-surrogacy: Application of IVF to women without functional uteri

Journal of In Vitro Fertilization and Embryo Transfer, 1989
Women with absent or dysfunctional uteri consented to controlled ovarian stimulation, ovum aspiration, in vitro fertilization, and embryo culture. Cleaving preembryos were transferred to recipient (surrogate) women whose menstrual cycles were in approximate synchrony with the ovum donor. None of the embryo recipients received medication.

Prematurely condensed human sperm chromosomes after in vitro fertilization (IVF)

Human Genetics, 1986
During an in vitro fertilization (IVF) program 122 inseminated eggs showing polar body extrusion, but neither formation of pronuclei nor cell cleavage were analysed cytogenetically. Nine of these eggs showed prematurely condensed sperm chromosomes of the G1-phase (G1-PCC) besides the haploid set of maternal metaphase II chromosomes. This phenomenon can

In vitro fertilization (IVF) and twin pregnancy outcomes

2022
Background: IVF treatment has been used to transfer multiple embryos leading to multiple pregnancies which are known to be associated with increased maternal and perinatal complications. One question is whether IVF itself contributes to these risks.

Successful parents of in vitro fertilization (IVF): The social repercussions

Journal of Assisted Reproduction and Genetics, 1992
A matched comparison was made of 157 parents of preschool twins conceived by one of the following: in vitro fertilization (IVF), infertility workup combined with infertility drug treatment, or spontaneously. The Interview Schedule for Social Interaction was used to examine systematically a comprehensive range of social relationships and the asymmetries
