Fish Sperm Subpopulations Detection, Separation, and Application: Current State and Trends

Reviews in Aquaculture, Volume 18, Issue 4, September 2026.
Modern advances in sperm biology highlight the necessity of recognising intra‐ejaculate heterogeneity as a central concept for advancing both the fundamental understanding of fertilisation processes and the development of artificial reproduction techniques in fishes. ABSTRACT Sperm subpopulations represent a fundamental manifestation of intra‐ejaculate

Biallelic Germline Inactivation of HROB Causes Primary Gonadal Insufficiency and is Potentially Associated with Colonic Polyposis Predisposition

American Journal of Medical Genetics Part A, Volume 200, Issue 8, Page 1773-1782, August 2026.
ABSTRACT The Homologous Recombination Factor With OB‐Fold (HROB) plays a role in homologous recombination and DNA replication, where it enhances the MCM8‐MCM9 helicase complex activity. Recent findings link biallelic germline HROB variants to primary gonadal insufficiency (hypergonadotropic hypogonadism), a phenotype also associated with MCM8/MCM9 ...

Mesenchymal stem cells promote ovarian reconstruction in mice

Stem Cell Research & Therapy
Background Studies have shown that chemotherapy and radiotherapy can cause premature ovarian failure and loss of fertility in female cancer patients. Ovarian cortex cryopreservation is a good choice to preserve female fertility before cancer treatment ...

An improved method for chromosome preparations from bovine oocytes and zygotes obtained by in vitro maturation and fertilization techniques

, 2010
Matured bovine oocytes and zygotes obtained by in vitro maturation and fertilization techniques (IVM and IVF) were cytogenetically prepared by using an improved method for chromosome preparations. The method, which involves use of trypsinizedhypotonic solution plus a vortex-agitated system and very cold two-step fixation process, contributes to weaken ...

The Therapeutic Potential of Stem Cell Therapy for Doxorubicin‐Induced Cardiotoxicity: A Narrative Review

Health Science Reports, Volume 9, Issue 8, August 2026.
ABSTRACT Background and Aims Doxorubicin (DOX) is a potent anthracycline chemotherapeutic agent whose clinical utility is significantly constrained by severe side effects, most notably DOX‐induced cardiotoxicity (DIC). Pathophysiological mechanisms of DIC include oxidative stress, mitochondrial dysfunction, programmed cell death, and inflammation ...

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

International Journal of Gynecology &Obstetrics, Volume 174, Issue 2, Page 718-729, August 2026.
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 ...

Final follicular maturation in the cow and its effects on the developmental potential of the oocyte [PDF]

, 1998
The use of assisted reproduction techniques can generate up to 27 (superovulation, SO) or 50 (in vitro embryo production, IVP) calves per cow per year instead of only one calf per cow per year after normal mating.
