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.

Study explains why men are more at risk for neurodevelopmental disorders

A new study has shed light on the reason why males are more at risk than females for neurodevelopmental disorders such as autism, schizophrenia and ADHD.

Antioxidants do not improve sperm quality

Researchers have found that despite studies that claim that antioxidants are good for sperm production, a new study has shown that there is no such benefit.

Over 8 million babies born from IVF since the birth of world's first test-tube baby

Forty years after the birth of Louise Brown, the world's first test-tube baby, an international committee monitoring progress in assisted reproduction reports today that the global total of babies born as a result of IVF and other advanced fertility treatments is "more than 8 million"

Antioxidants do not improve sperm quality in infertile men, finds study

A large clinical trial has shown that daily antioxidant supplementation among men with infertility does not make a difference to the quality of their sperm.

Lack of stable partner is major reason for women freezing their eggs, shows study

Contrary to common suggestion, women are opting to freeze their eggs not to pursue education or careers but for reasons "mostly revolving around women's lack of stable partnerships with men committed to marriage and parenting".

PMDA approves use of LYNPARZA in patients with BRCA-mutated breast cancer

AstraZeneca and Merck, known as MSD outside the United States and Canada, today announced that Japan's Pharmaceuticals and Medical Devices Agency has approved LYNPARZA tablets for use in patients with unresectable or recurrent BRCA-mutated, human epidermal growth factor receptor 2 -negative breast cancer who have received prior chemotherapy.

New Rekovelle analysis shows AMH is robust predictor of ovarian response to fertility treatment

Ferring Pharmaceuticals announced today a new analysis of data from the Phase 3 ESTHER-1 trial showing that natural variations in anti-Müllerian hormone levels during and between a woman's menstrual cycle have no clinically relevant impact on ovarian response when using AMH to dose Rekovelle for ovarian stimulation.

Researchers discover novel function of fibroblast growth factor 2 for spermatogonial stem cell

A research team found a novel function of fibroblast growth factor 2, a self-renewal factor for spermatogonial stem cell which is the origin of the sperm production.

Preconception binge drinking may have negative effect on future offspring

A rat model found preconception binge drinking may have negative consequences on future offspring's growth, social interactions and pubertal development, according to a new study published in the Endocrine Society's Journal of the Endocrine Society.

Researchers develop new method to preserve fertility in boys with prepubertal cancer

Ben-Gurion University of the Negev and Soroka University Medical Center researchers in Beer-Sheva, Israel are developing a cell culture system that for the first time can change testicular stem cells into sperm-like cells that may enable future fertility for boys with prepubertal cancer.

European Union's criteria for regulating EDCs do not go far enough to protect public health

The Endocrine Society expressed continued concerns today that the European Union's (EU's) criteria for regulating endocrine-disrupting chemicals (EDCs) in pesticides and biocides do not go far enough to protect public health.

Mapping the Genes Responsible for Pluripotency

Dr. Atilgan Yilmaz and his team have developed a method by which they can produce haploid human embryonic stem cells from oocytes. They combined this technique with CRISPR-Cas9 to generate an atlas of the genome, containing the functions of over 18,000 genes.

Celgene to share new and updated data around novel hematological therapies

Celgene Corporation today announced that data from a broad range of early and late stage studies evaluating Celgene investigational agents and investigational uses of marketed products will be presented at the 23rd European Hematology Association annual meeting in Stockholm, Sweden, from June 14-17, 2018.

Male depression reduces the chances of getting pregnant, finds new study

A new study has shown that among couples being treated for infertility, male depression was associated with lower pregnancy rates.

Study identifies critical role of protein in sperm tail development

The group led by ICREA Research Professor Cayetano Gonzalez at the Institute for Research in Biomedicine, in collaboration with Giuliano Callaini's team at the University of Siena in Italy, has published a study in The Journal of Cell Biology that identifies the critical role played by a protein called CENTROBIN in sperm tail development.

Taurine deficiency in sperm linked to male infertility

Sperm are highly specialized cells adapted to achieve a single goal: fertilize an egg. Along the road to fertilization sperm must embark on a lengthy journey to the female oviduct, avoiding several fatal stresses that occur when they pass through different physiological environments.

Study: Environmental pollutants affect male reproduction in many species, including humans

In the St. Lawrence River near Montreal's sewage discharge site, male spottail shiners show the effects of pollution with more than one third of the fish having oocytes in their testes.

Stem cells cultured in vitro self-assemble into embryo

An embryo has been created in vitro from mouse stem cells cultured with a 3D scaffold. The resulting structure was remarkably similar to a natural mouse embryo.

Advances in genetic testing give new insights to parents of children with epileptic encephalopathy

Advances in genetic testing offer new insights to parents who have a child with a rare but serious form of epilepsy, epileptic encephalopathy (EE), found in one of about every 2,000 births and characterized by developmental disabilities as well as horrible seizures.

Scientists identify gene responsible for evolution of recombination rates

Genetics is a crapshoot. During sexual reproduction, genes from both the mother and the father mix and mingle to produce a genetic combination unique to each offspring. In most cases, the chromosomes line up properly and crossover. In some unlucky cases, however, "selfish DNA" enters the mix, causing abnormal crossovers with deletions or insertions in chromosomes, which can manifest as birth defects.
