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.

INRS researchers evaluate how chemotherapy among men affects health of future generations

How do cancer and cancer treatments affect the reproductive function of men? Can this affect the health of their direct descendants and subsequent generations? To get a clear picture, INRS researchers evaluate the current state of knowledge on this public health issue in a review article appearing in the journal Gynécologie Obstétrique & Fertilité.

Distinct small differences in the human brain may contribute to our cognitive abilities

The most dramatic divergence between humans and other primates can be found in the brain, the primary organ that gives our species its identity.

IVF, ICSI pregnancies lead to increased risk of congenital heart defects in newborns

A new analysis of published studies found a 45% increased risk of congenital heart defects in newborns when women become pregnant via in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) than through spontaneous conception.

Live births more likely to occur in women with sufficient vitamin D, research finds

Researchers are calling for a randomized clinical trial to investigate the potential role of vitamin D supplementation in improving live birth rates following assisted reproduction treatment.

New research sheds light on negative effects of stress on the brain

Stress can have numerous harmful effects on the mind and body, both immediately and over long periods of time. New research reveals mechanisms by which stress exacts its toll throughout the body, from the brain to the male reproductive system, and points to potential paths for reducing the negative effects of stress.

Choosy eggs and vying sperm may hold secrets about evolution of new species

The delicately mannered dance between discerning eggs and vying sperm is more complicated than scientists once believed, and it may hold secrets about the evolution of new species.

Research casts light on how chromosomes 'cheat' for chance to get into a sex cell

Each of your cells contains two copies of 23 chromosomes, one inherited from your father and one from your mother. Theoretically, when you create a gamete -- a sperm or an egg -- each copy has a 50-50 shot at being passed on. But the reality isn't so clearcut.

Could marijuana be an aphrodisiac?

A new study is the first to show that regular use of marijuana or cannabis is linked to having more sex. The study by the Stanford researchers assessed the use of marijuana and frequency of sexual intercourse among participants in the United States. Results were unprecedented.

Study supports that weekend work may not be needed for most IVF/ICSI treatments

It's unclear whether there is a need to retrieve a woman's eggs on weekends, in connection with in vitro fertilization/intracytoplasmatic sperm injection (IVF/ICSI) treatment in couples wishing to conceive.

What men need to know: Prevention, diagnosis, and treatment of prostate cancer

Prostate cancer is the second leading cause of cancer death in men. Next to skin cancers, prostate cancer is the most common cancer diagnosed in American men.

Synthetic compound targets enzyme that supports survival and dissemination of metastatic cells

Cancer can most often be successfully treated when confined to one organ. But a greater challenge lies in treating cancer that has metastasized, or spread, from the primary tumor throughout the patient's body.

Study finds link between sleep duration and measure of chromosomal health in sperm

A new study found a link between sleep duration and a measure of chromosomal health in sperm. The findings are published in the Journal of Sleep Research.

Researchers find multiple new mutations linked to autism in children but not their parents

Most cases of autism appear to be associated with the appearance of new mutations that are not inherited from the child's parents, researchers from the University of Washington School of Medicine report.

Research expands range in dry preservation of mammalian sperm cells

In a paper forthcoming in the November issue of the journal Theriogenology, a team of researchers from the University of North Carolina at Charlotte and the Smithsonian Conservation Biology Institute, announced the first successful drying and rehydration of domestic cat spermatozoa using a rapid microwave dehydration method.

Birth control method for men by gene editing

Researchers at the Michigan State University have come closer to finding an effective method of male contraception. Men have been notorious in not choosing to be responsible of their fertility and not adopting contraception.

Genetic discovery provides strong lead for future research on male contraception

When it comes to birth control, many males turn to two options: condoms or vasectomies. While the two choices are effective, both methods merely focus on blocking the transportation of sperm.

New serotypes of Zika virus could appear in near future, researcher cautions

Zika virus is mutating so fast in Brazilian patients that different serotypes of the pathogen could appear in the near future, as is already the case with dengue virus. This would hinder the production of a vaccine and impair the effectiveness of the diagnostic tests already developed.

Researchers propose LSD1 protein as central player in Alzheimer's and FTD

Removal of a regulatory gene called LSD1 in adult mice induces changes in gene activity that that look unexpectedly like Alzheimer's disease, scientists have discovered.

Study sheds light on complex process involved in development of sperm stem cells

New research from scientists at Huntsman Cancer Institute at the University of Utah and collaborators at University of Utah Health sheds light on the complex process that occurs in the development of human sperm stem cells.

Study finds underutilization of sperm banking by at-risk patients with cancer

A comprehensive study of adolescent and young adult cancer patients found just 43.8 percent of those at risk for infertility banked sperm prior to cancer therapy, suggesting that patients might benefit from efforts to increase awareness and understanding of the option.
