Live Births Following Zona Pellucida–Binding Sperm Selection in Recurrent Implantation Failure: Two Case Reports

Fertility & Reproduction
Recurrent implantation failure (RIF) poses a significant challenge in assisted reproductive technologies (ART). Intracytoplasmic sperm injection (ICSI), while effective for male factor infertility, bypasses natural sperm selection, potentially reducing ...

Age, embryo donor status, and insemination with chilled semen all predispose to persistent breeding‐induced endometritis in warmblood mares

Equine Veterinary Journal, EarlyView.
Abstract Background Persistent breeding‐induced endometritis (PBIE) is a common reason for mares failing to establish pregnancy. Objective To examine the hypothesis that advancing mare age and embryo donor status predispose to PBIE and compromise fertility.

Possible consequences of performing intracytoplasmic sperm injection (ICSI) with sperm possessing nuclear DNA damage [PDF]

, 2000
A number of studies have confirmed that sperm with damaged nuclear DNA are present in human ejaculate. It appears that these sperm are more likely to occur in men with low concentrations of sperm, or poor sperm motility or morphology.

Bovine oocyte activation with bull or human sperm by conventional ICSI and Piezo-ICSI: Its relationship with PLCɀ activity

Open Veterinary Journal
Background: Intracytoplasmic sperm injection (ICSI) technique has low efficiency in cattle. This has mainly been attributed to the oocyte activation failure due to oocyte and/or sperm factors.

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 ...

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
