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.

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

Cytogenetic analysis of in vitro fertilization (IVF) failures

Human Genetics, 1989
Cytogenetic studies were carried out on 150 oocytes obtained in a human in vitro fertilization (IVF) program. Although all cells lacked signs of fertilization at light microscopy, 46 (30.7%) appeared to show cytological evidence of fertilization.

In vitro DNA fluorescence after in vitro fertilization (IVF) failure

Journal of Assisted Reproduction and Genetics, 1992
A pilot study was performed to test the diagnostic value of in vitro DNA fluorescence in oocytes that failed to fertilize after IVF. Ten patients with a cleavage rate less than 20% after IVF were included.Uncleaved oocytes were observed by fluorescence microscopy after incubation with the DNA fluorescent dye Hoeschst 33342.

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.

In vitro fertilization (IVF) in Sweden: Risk for congenital malformations after different IVF methods [PDF]

Birth Defects Research Part A: Clinical and Molecular Teratology, 2005
BACKGROUND: The possible excess of congenital malformations in infants born after in vitro fertilization (IVF) has been much discussed in the literature, with controversial conclusions.

Early pregnancy wastage in IVF (in vitro fertilization) patients

Journal of In Vitro Fertilization and Embryo Transfer, 1991
Human in vitro fertilization is characterized by a low efficiency of implantation. Possible mechanisms for pregnancy loss are discussed. Embryo viability or quality, abnormal implantation, and delayed or absent corpus luteum rescue may all play a role in pregnancy wastage. Defining the possible mechanism for these losses may allow hormonal treatment to

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

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

IVF/GDE3 - In Vitro Fertilization method coupled to GDE3

2019 IEEE Congress on Evolutionary Computation (CEC), 2019
The In Vitro Fertilization Module (IVFm) is a promising method applicable to mono-objective and multiobjec-tive problems, especially for complex and multimodal ones. Its mono-objective implementation coupled to Genetic Algorithm (IVF/GA) and its multiobjective implementation coupled to NSGA-II (IVF/NSGAII) presented promising results due to the balance
