Lifestyle factors like an unhealthy diet can worsen the effects of genetic causes of male infertility, according to a proof-of-concept study published in Human Reproduction. Led by Dr Jessica Dunleavy and Professor Moira O’Bryan from the University of Melbourne’s School of BioSciences, the research used a mouse model carrying defects in the M1AP gene to … Read more
Texas A&M University researchers are investigating the paternal role in early pregnancy loss, shifting focus to sperm epigenetics and male fertility factors that affect over 50% of human conceptions and roughly half of cattle pregnancies. According to Lacey Luense, Ph.D., an assistant professor in the Texas A&M College of Agriculture and Life Sciences Department of … Read more
New research identifies specific serum metabolite thresholds in Holstein dairy cows that can predict reproductive and health disorders. By monitoring metabolic markers like NEFA, BHBA, and calcium, producers can now target nutritional interventions to improve fertility and prevent early culling in transition cows. Predicting Health Risks Through Serum Metabolites A study of 366 Holstein cows … Read more
Recent research reveals that arthropod fertilization often relies on sperm cooperation rather than individual competition, reshaping evolutionary biology understandings of reproduction. According to a study published in Nature Communications by evolutionary biologists from Syracuse University, the University of Siena, and the University of Szeged, sperm cells in numerous species form coordinated groups using sperm-associated material … Read more
Endometriosis, a reproductive condition affecting roughly 1 in 10 women worldwide, can now be detected through a non-invasive saliva test called Endotest, following approval from the National Institute for Health and Care Excellence (NICE) in the UK. According to Yale Medicine, women face an average wait of 11 years between their first symptoms and a … Read more
A May 2026 survey of 1,200 women conducted by Mira reveals that 97% of respondents prefer to prioritize understanding their physiological health over merely treating isolated symptoms. Despite this desire for deeper insight, 95% of those surveyed reported feeling forced to manage their own health journeys without adequate professional guidance, leading many to rely on … Read more
The rise of unregulated online sperm donation in Australia is being driven by a significant supply-demand gap in clinical fertility services. With clinic-based sperm costing between $2,000 and $3,500 per vial plus additional IVF fees, many prospective parents are turning to social media groups to bypass costs, despite warnings from legal and medical experts regarding … Read more
Modern IVF treatments now achieve a 68.2% cumulative live birth rate over three cycles while maintaining a multiple birth rate of just 2.9%, according to research presented at the 42nd Annual Meeting of the European Society of Human Reproduction and Embryology (ESHRE). This represents a significant improvement over historical methods that often resulted in multiple … Read more
Men in northern Spain have nearly double the total motile sperm count of those in central Spain, according to a multicentre study presented at the 42nd Annual Meeting of the European Society of Human Reproduction and Embryology (ESHRE). The research suggests environmental pollutants, rather than lifestyle habits, drive these regional disparities in male fertility. Why … Read more
Researchers at Karolinska Institutet have successfully generated early germ cells from cryopreserved testicular tissue taken from prepubertal boys who underwent cancer treatment. Published in Human Reproduction Open, the study provides a proof-of-concept that somatic cells from damaged tissue can be reprogrammed into induced pluripotent stem cells (iPSCs) and subsequently directed to become primordial germ cells, … Read more
