Advancing conservation breeding programs for marine invertebrates

open access: yesConservation Biology, EarlyView.
Abstract In the face of ecosystem change and biodiversity loss caused by climate change and other stressors, conservation breeding, or captive breeding, with the aim of reintroduction for wild population recovery, is an emerging tool for preventing species’ extinction and rehabilitating ecosystems.

Preimplantation Genetic Testing for Families at Risk of Haemophilia: Ten‐Year Single‐Centre Experience

open access: yesHaemophilia, EarlyView.
ABSTRACT Introduction Preimplantation genetic testing for monogenic diseases (PGT‐M) is a reproductive option for couples at high risk of transmitting inherited disorders. We report a ten‐year single‐centre PGT‐M experience in families at risk of hemophilia.

Spotted wolffish (Anarhichas minor) sperm cryopreservation in 5-mL cryovials [PDF]

open access: yes, 2020
In spotted wolffish Anarhichas minor aquaculture, cryopreservation is used to secure sperm availability throughout the entire spawning season. Under current protocols, sperm is cryopreserved in 0.5-mL straws. This implies thawing a considerable number of

Protective effect and mechanisms of marine antifreeze protein product on sperm cryodamage in livestock

open access: yes浙江大学学报. 农业与生命科学版, 2020
Antifreeze proteins (AFPs), a class of antifreeze substances, were initially found to bind to ice crystals in vivo, thereby contributing to inhibition of the growth of ice crystals that enabled polar fish to survive at the temperatures below freezing ...

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

open access: yesReviews 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

Effect of Three Semen Extenders on Sperm Quality and In Vitro Fertilization Rates of Fresh and Cryopreserved Sperm Collected from Llama (Lama glama) Vas Deferens

open access: yesAnimals
The advances in Assisted Reproductive Technologies (ARTs) applied in South American camelid species are still scarce. The aim of this study was to compare the effects of three semen extenders, before and after the cryopreservation of spermatozoa obtained

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

open access: yesJournal of Ultrasound in Medicine, Volume 45, Issue 8, Page 1647-1653, August 2026.
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 ...

Epididymosome‐Supplemented Extender Induces Changes in Morpho‐Functional Traits and microRNA Levels of Post‐Thaw Sperm and Improves Embryo Developmental Potential

open access: yesMolecular Reproduction and Development, Volume 93, Issue 8, August 2026.
ABSTRACT While molecular signature contributes to sperm quality and fertility potential, sperm may lost key molecules during cryopreservation. Since sperm cells are transcriptionally inert and rely on interactions with epididymosomes (epEVs) to acquire molecules, herein, we investigated the effects of the addition of epEVs to the cryopreservation ...

The effect of two pre-cryopreservation single layer colloidal centrifugation protocols in combination with different freezing extenders on the fragmentation dynamics of thawed equine sperm DNA [PDF]

open access: yes, 2012
Variability among stallions in terms of semen cryopreservation quality renders it difficult to arrive at a standardized cryopreservation method. Different extenders and processing techniques (such us colloidal centrifugation) are used in order to ...

Antioxidant supplementation of cryopreservation extenders improves post-thaw sperm viability in the red-crowned toadlet, Pseudophryne australis

open access: yesFrontiers in Amphibian and Reptile Science
Amphibians are currently experiencing the highest extinction rate of any vertebrate class. Gamete cryopreservation and the biobanking of genetic resources are important conservation tools to safeguard the genetic diversity of imperiled species.
