The association between IVF and chromosomal abnormalities compared to spontaneous conception

Journal of Biochemical and Clinical Genetics, 2021
In vitro fertilization (IVF) is a process by which an egg is extracted by needle aspiration and then combined with a sperm so that fertilization can occur outside the body. Genetic defects, such as chromosomal abnormalities, are considered rare among the

Predictive factors for ovarian response in a corifollitropin alfa/GnRH antagonist protocol for controlled ovarian stimulation in IVF/ICSI cycles [PDF]

, 2015
Background This secondary analysis aimed to identify predictors of low (<6 oocytes retrieved) and high ovarian response (>18 oocytes retrieved) in IVF patients undergoing controlled ovarian stimulation with corifollitropin alfa in a gonadotropin-

Optimizing outcomes in intrauterine insemination: A narrative synthesis of two decades of clinical research (2000–2024)

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Intrauterine insemination (IUI) is a widely used first‐line fertility treatment, yet its success rates vary considerably. This review synthesizes evidence from peer‐reviewed studies published between 2000 and 2024, including randomized controlled trials, cohort and case–control studies, as well as systematic and narrative reviews identified ...

Luteal phase stimulation versus follicular phase stimulation in poor ovarian responders: A systematic review and a meta‐analysis

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Background Poor ovarian response (POR) complicates a substantial proportion of in vitro fertilization (IVF) cycles, frequently causing cycle cancellation and suboptimal reproductive outcomes. Conventional follicular‐phase ovarian stimulation (FPOS) protocols often yield limited results, prompting the evaluation of alternative strategies such ...

Micro-rubbing sperm immobilization promotes fertilization and oocyte utilization in intracytoplasmic sperm injection

Journal of Ovarian Research
Background Sperm immobilization is an important step in intracytoplasmic sperm injection (ICSI) as it is necessary for oocyte activation by the spermatozoa. Several techniques are available for sperm immobilization.

Lower developmental potential of rat zygotes produced by ooplasmic injection of testicular spermatozoa versus cauda epididymal spermatozoa

The Journal of Reproduction and Development
Intracytoplasmic sperm injection (ICSI) is clinically used to treat obstructive/nonobstructive azoospermia. This study compared the efficacy of ICSI with cauda epididymal and testicular sperm in Wistar (WI) and Brown-Norway (BN) rats.

Increased incidence of cytogenetic abnormalities in chorionic villus samples from pregnancies established by in vitro fertilization and embryo transfer (IVF-ET) [PDF]

, 1995
We studied 201 pregnancies that were established by in vitro fertilization and embryo transfer (IVF–ET) and compared the frequency of cytogenetic abnormalities with that found in a large control population matched for indication group (advanced maternal ...

The Oocyte/Antral Follicle Count Index: Does Maximizing Oocyte Yield Translate into Better Assisted Reproductive Technology Outcomes?

Journal of Ultrasound in Medicine, EarlyView.
Objectives Whether aspiration of more oocytes than the antral follicle count (AFC) is beneficial for the current and future products of assisted reproductive technologies (ART) cycles. Methods Data of the first oocyte aspiration for intracytoplasmic sperm injection performed between 2018 and 2022 in attempt to conceive (ICSI, n = 399) or for planned ...

Recent advances in micromanipulation and transgenesis in domestic mammals [PDF]

, 2011
Background: Intracytoplasmic sperm injection (ICSI) involves mechanical transfer of a single sperm cell into ooplasm. A new application has been recently found for ICSI, the production of transgenic animals. Since the birth of ‘‘Dolly’’, the first adult
