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.

Sperm and eggs of transgenders to be stored by NHS before sex changes

Several transgender adolescents are opting to freeze their eggs and sperm with the Britain's NHS to leave an option for parenthood later in life open, according to doctors.

Potential Zika vaccine blocks mother-to-fetus transmission and stops male testis infection

For the first time, a collaborative team led by The University of Texas Medical Branch at Galveston has shown that a potential Zika vaccine quickly can protect fetuses against infection as well as protect males against testicular infection and injury.

Study shows link between obesity and low sperm quality

The journal Andologia has published the first report of abnormal sperm parameters in obese men based on computer aided sperm analysis. The findings suggest that clinicians may need to factor in paternal obesity prior to assisted reproduction.

Scientists uncover new clues to male infertility or congenital illness

When it comes to male reproductive fertility, timing is everything. Now scientists are finding new details on how disruption of this timing may contribute to male infertility or congenital illness.

Research unravels how stem cells in the ovaries may be harnessed to revolutionize fertility treatments

About 13 years ago, Northeastern professor Jonathan Tilly, a reproductive biologist, made a discovery that challenged everything scientists thought they knew about female reproduction. The long-held belief that mammals were born with a set number of eggs -- and no ability to create new ones -- was wrong.

Phthalate levels in expectant fathers influence sperm epigenetics, study suggests

Early results from a larger, ongoing study led by environmental health scientist Richard Pilsner at the University of Massachusetts Amherst suggest that phthalate levels in expectant fathers have an effect on couples' reproductive success via epigenetic modifications of sperm DNA.

Fathers can influence offspring sex ratios, mice study shows

It has traditionally been thought that in mammals only mothers are able to influence the sex of their offspring.

Bariatric surgery in men linked to frequent sperm aberrations and lower fertility rates

A meta-analysis of studies in which men underwent Roux-en-Y gastric bypass (RYGB) procedures found frequent sperm aberrations and lower fertility rates despite improvements in weight, androgen levels, and sexual quality of life following the procedure.

Mutations altering gene function play role in development of intellectual disabilities

Intellectual disabilities are often caused by a mutation that damages a gene, preventing the associated protein from functioning properly.

Scientists question CRISPR human embryo editing claims

A paper published in the journal Nature on the 2nd August described how a gene editing tool CRISPR could be used to correct a genetic mutation that leads to a heart condition. This team had performed the genetic editing on the gene sequences in dozens of viable human embryos to attempt to prevent a genetic heart condition called hypertrophic cardiomyopathy.

Average paternal age rises in the USA

According to a latest study by the researchers at the Stanford University School of Medicine, the average age of fathers of the new born babies in United States has risen by 3.5 years over the last four decades. The study was published yesterda in the journal Human Reproduction.

Mammal embryos discard paternal mitochondria within days of fertilization, new study shows

Mammal embryos shed paternal mitochondria within days of fertilization, perhaps to ensure the offspring a healthy life, a new study shows.

29 Aug 2017

Long non-coding RNAs could represent novel male infertility drug targets

Scientists have found distinctive portions of genetic material--known as lncRNAs--that help sperm develop. Male mice lacking a particular lncRNA have low sperm count, suggesting lncRNAs could represent novel infertility drug targets.

Scientists use novel cell tracing method to describe testicular macrophages

The origin, development, and characteristics of two types of testicular macrophage have been described by a CNRS team at the Centre d'Immunologie de Marseille-Luminy.

Researchers investigate genetic mutations in sperm cells to help prevent birth defects

It's about preventing birth defects. Associate pharmaceutical sciences professor Wenfeng An and his team at South Dakota State University are investigating mobile DNA segments, known as L1s, in sperm cells with the goal to treat families at risk for genetic mutations before they conceive.

Tiny lab-grown structures that resemble amniotic sac may help in infertility research

The first few weeks after sperm meets egg still hold many mysteries. Among them: what causes the process to fail, leading to many cases of infertility.

Researchers identify new genetic mutation that prevents sperm production

Researchers at Ben-Gurion University of the Negev and Soroka University Medical Center in Beer-Sheva, Israel have discovered a new genetic mutation that prevents sperm production.

Researchers explore genetic differences, hereditary factors involved in hemiplegic cerebral palsy

Hemiplegic cerebral palsy hampers movement in one side of a person's body. In the first genetic study of its kind to exclusively focus on those with hemiplegic cerebral palsy, a group of 26 Canadian researchers has investigated the genetic differences and hereditary factors involved in this neurodevelopmental condition.

In-depth tumor sequencing reveals key molecular drivers of metastatic cancers

Five hundred cancer patients are getting an in-depth look at their genomes as part of a new clinical study that is revealing some of the key molecular drivers of metastatic cancers.

Study shows new method for repairing disease-causing mutation in human embryos

Scientists have demonstrated an effective way of using a gene-editing tool to correct a disease-causing gene mutation in human embryos and stop it from passing to future generations.
