The term sperm refers to the male reproductive cells. In the types of sexual reproduction known as anisogamy and oogamy, there is a marked difference in the size of the gametes with the smaller one being termed the "male" or sperm cell. The human sperm cell is haploid, so that its 23 chromosomes can join the 23 chromosomes of the female egg to form a diploid cell.

New study provides convincing evidence of the essential role of cylicins in sperm development and fertility

Researchers investigated the Role of Cylicins in Spermiogenesis and Male Fertility in Mice and Humans through Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)/ CRISPR-associated protein 9 (Cas9) Gene Editing.

Nut consumption linked to improved male fertility, systematic review reveals

A systematic review finds that consuming at least 60 grams of nuts daily significantly enhances male fertility by improving sperm vitality, motility, and morphology, while evidence for nut consumption's impact on female fertility remains limited.

Study links heavy mobile phone use to lower sperm count

Swiss study finds higher mobile phone use linked to lower sperm count and concentration in young men, raising concerns about RF-EMF exposure's impact on male reproductive health. Despite limitations, the research suggests a potential risk to fertility with increasing phone usage.

Highly sensitive blood test shows promise for early detection of common deadly cancers

Most cancers become deadly by keeping a low profile, causing no symptoms until they're too advanced to treat. Ovarian and gastroesophageal cancers are among the most notorious for this sly disease progression, often leading to late-stage diagnoses.

Study shows link between mobile phone use and semen quality of young men

Does electromagnetic radiation emitted by mobile phones affect semen quality? While various environmental and lifestyle factors have been proposed to explain the decline in semen quality observed over the last fifty years, the role of mobile phones has yet to be demonstrated.

How one gene shakes up our understanding of male infertility

The study investigates the role of the ACTL7B gene in sperm formation using genetically modified mice and finds that deficiencies in this gene lead to failed spermatogenesis and structural sperm abnormalities. Given the gene's similarity in humans, the findings suggest ACTL7B could serve as a potential biomarker for male infertility.

Loss of structural protein ACTL7B blocks spermatogenesis in male mice

Mature spermatozoa are characterized by an head, midpiece and a long tail for locomotion. Now, researchers from the University Hospital Bonn (UKB) and the Transdisciplinary Research Unit "Life & Health" at the University of Bonn have found that a loss of the structural protein ACTL7B blocks spermatogenesis in male mice.

Study finds no link between anxiety or depression and IVF outcomes in men

In vitro fertilization (IVF) is a time-intensive and often stress-inducing fertility procedure. Yet how does that stress impact its success? Investigators at Brigham and Women's Hospital, a founding member of the Mass General Brigham healthcare system, assessed the effects of anxiety and depression in men on fertility and IVF outcomes.

Does smoking tobacco damage sperm quality?

Tobacco smoking is linked to diminished semen quality by triggering stress reactions in sperm cells, a study in the journal Antioxidants reveals. Researchers identified that smokers had poorer sperm quality, possibly due to elevated stress responses in their sperm cells.

Do environmental and occupational factors influence semen quality?

New research sheds light on how environmental and occupational factors impact male fertility, revealing that proximity to power lines may enhance semen quality while living near chemical factories could be detrimental. The study emphasizes the need for a deeper understanding of these factors in the context of rising infertility rates.

Mapping the human body one cell at a time: New study reveals the intricate relationship between cell size and count

A study published in PNAS provides a comprehensive look at the relationship between cell size and count across the human body, drawing from over 1,500 sources and identifying around 400 unique cell types. The research reveals an almost inverse relationship between cell size and count, offering a quantitative framework that could serve as a baseline for understanding cellular composition and function in various applications.
