ACROSIN deficiency identified as a cause of total fertilization failure and thus, male infertility in humans

In a most recent study, Hua and colleagues have identified a rare homozygous nonsense mutation in the ACR gene as a causative factor for male infertility, specifically leading to Total Fertilization Failure (TFF) during in vitro fertilization (IVF) attempts. The findings, published in Human Reproduction, shed light on the genetic basis of TFF, offering new …

Excessive mobile phone usage linked to potential decrease in sperm count

Over the last decades, mobile phones have become ubiquitously used regardless of people’s age, cultural background, gender, or geographical location. However, little is known about the impact on general fertility of the radiofrequency electromagnetic fields (RF-EMF) emitted by these devices, which can be absorbed by the human body. Specifically in the case of male fertility, …

Childhood cancer and hematological disorders negatively affect spermatogonial quantity at diagnosis: a retrospective study of a male fertility preservation cohort

For young boys with cancer or a non-malignant hematological disorder, conditioning therapy, abdominal/pelvic radiotherapy, and certain chemotherapies form a major risk for germ cell loss. Contradictory studies have investigated the direct effects of such diseases on the development of the prepubertal male gonad before mainline treatment. For health professionals to counsel pediatric patients in the …

Temperature sensitivity of DNA double-strand break repair underpins heat-induced meiotic failure in mouse spermatogenesis

Kodai Hirano, Yuta Nonami, Yoshiaki Nakamura, Toshiyuki Sato, Takuya Sato, Keiichiro Ishiguro, Takehiko Ogawa, *Shosei Yoshida Background Spermatogenesis in mammals is a temperature-sensitive developmental process that occurs at a few degrees below the core body temperature of 38 °C. Elevated testis temperatures disrupt spermatogenesis at various phases, leading to male infertility. Artificial cryptorchidism, which involves surgically …
