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.

Merck announces FDA Advisory Committee approval of GARDASIL for anal cancer and AIN treatment

Merck announced today that the U.S. Food and Drug Administration's (FDA) Vaccines and Related Biological Products Advisory Committee has advised that the data presented support an indication for GARDASIL® [Human Papillomavirus Quadrivalent (Types 6, 11, 16, and 18) Vaccine, Recombinant] for the prevention of anal cancer and anal intraepithelial neoplasia (AIN) in both males and females 9 through 26 years of age.

Contraceptive, antiviral gel using bee venom wins 2010 Gates Foundation grant

A vaginal gel that affords both contraception and HIV protection using nanoparticles that carry bee venom is one of the bold, unconventional ideas that won a 2010 Grand Challenges Explorations grant from the Bill & Melinda Gates Foundation.

Study finds infertility treatment does not increase risk of cerebral palsy in IVF/ICSI children

Doctors have known for some time that children born after fertility treatments such as in vitro fertilisation (IVF) or intracytoplasmic sperm injection (ICSI) are at increased risk of cerebral palsy. However, it was not known whether this risk was due to the treatment itself, the higher frequency of preterm or multiple births, or a mechanism associated with couples' underlying infertility.

New technique could help scientists to predict how living prostate tissues respond to therapy

Scientists at the Johns Hopkins Kimmel Cancer Center, University of Helsinki and Stanford University have developed a technique to keep normal and cancerous prostate tissue removed during surgery alive and functioning normally in the laboratory for up to a week.

UB endocrinologist receives Junior Faculty Award to study effects of low testosterone in young men with type 2 diabetes

An endocrinologist in the University at Buffalo's School of Medicine and Biomedical Sciences has received a three-year $400,000 Junior Faculty Award from the American Diabetes Society to study the effects of low testosterone levels in young men with type 2 diabetes.

Inefficient suppression of DUX4 gene causes facioscapulohumeral dystrophy: Study

An international team of researchers led by an investigator from Fred Hutchinson Cancer Research Center has made a second critical advance in determining the cause of a common form of muscular dystrophy known as facioscapulohumeral dystrophy, or FSHD.

High urine BPA levels associated with decreased sperm quality

Increasing urine BPA (Bisphenol-A) level was significantly associated with decreased sperm concentration, decreased total sperm count, decreased sperm vitality and decreased sperm motility, according to a Kaiser Permanente study appearing in the journal of Fertility and Sterility.

Experts urge clinicians to discuss sperm banking with male cancer patients

Many men whose fertility may be at risk from cancer treatment are not being offered the chance to store their sperm according to new research published today in the Annals of Oncology (Thursday).

deCODE genetics publishes high resolution recombination map of human genome in Nature journal

Scientists from deCODE genetics today publish in Nature the highest resolution recombination map of the human genome yet developed. Recombination is the reshuffling of the genome that occurs in the formation of eggs and sperm: we inherit one version of each chromosome from each of our parents, and create novel blends of the two that we pass on to our offspring.

PCT technology improves DNA extraction method in forensic evidentiary samples

Pressure BioSciences, Inc. today announced that two scientific presentations at the 21st International Symposium on Human Identification have provided further evidence that pressure cycling technology offers an improved method for the extraction of DNA in the analysis of forensic evidentiary samples.

Endocrine disrupting chemicals may affect human reproductive system: Research

New research has provided the first evidence that 'gender bending' chemicals which find their way from human products into rivers and oceans can have a significant impact on the ability of fish to breed in UK Rivers.

Cryo-Cell formalizes industry-exclusive agreement with MedTech For Solutions GPO

Cryo-Cell International, Inc., one of the world's largest and most established family cord blood banks and global stem cell innovators, today announced at the annual meeting of the American Society of Reproductive Medicine (ASRM) that the Company has formalized an industry-exclusive agreement with MedTech For Solutions, Inc., a Group Purchasing Organization (GPO) representing a member network of 115 practices specializing in reproductive medicine, which operates in conjunction with The Broadlane Group.

First step in development of artificial human testicle

After more than 30 years of unsuccessful efforts by numerous investigators, researchers have now found a way to propagate primary human Sertoli cells in the laboratory. Derived from the testis, it has been difficult to maintain Sertoli cells, the "nurse" cells responsible for overseeing sperm production, outside of the human body.

Examining genetic material of egg cells may inform about embryos health

Fertility procedures such as in vitro fertilization (IVF) require a couple and the doctor to place the risky bet that the multiple eggs they choose to fertilize will produce an embryo that will thrive in the uterus. Researchers cannot biopsy eggs directly because that would destroy them, but a new discovery by professors at Brown University and Women & Infants Hospital could lead to new insights about how eggs develop and ultimately inform judgments about how the embryos they produce will fare. The idea is to examine the genetic material the egg cells discarded when they were first forming, to see which genes they were expressing.

Cryo-Cell to launch new reproductive tissue service for cryopreserved embryos, oocyctes

Cryo-Cell International, Inc. one of the world's largest and most established family cord blood banks and global stem cell innovators, today announced plans at the annual meeting of the American Society of Reproductive Medicine (ASRM) to launch Cryology RTS, a new reproductive tissue storage service for cryopreserved embryos, oocyctes and sperm.

Research determine 3D structure of egg receptor molecule that binds sperm

Researchers at the Swedish medical university Karolinska Institutet have been able to describe the 3D structure of a complete egg receptor that binds sperm at the beginning of fertilization. The results, published in the journal Cell, will lead to better understanding of infertility and may enable entirely new types of contraceptives.

Researchers suggest 'watch and wait' strategy for girls with germ-cell ovarian tumors

Researchers from Dana-Farber/Children's Hospital Cancer Center (DF/CHCC) have found that as many as 50 percent of young girls treated for germ-cell ovarian tumors might safely be spared chemotherapy using a "watch and wait" strategy to determine if the follow-up treatment is needed.

Scientists identify root cause of chromosomal errors and gene diversity

A team led by a scientist at the University of Pittsburgh School of Medicine has discovered a regulatory protein that influences where genetic material gets swapped between maternal and paternal chromosomes during the process of creating eggs and sperm. The findings, which shed light on the roots of chromosomal errors and gene diversity, appear in tomorrow's issue of Nature.
