Sperm News and Research

RSS

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.

People with type 1 diabetes could grow their own insulin-producing cells, say researchers

At the annual meeting of the American Society for Cell Biology last week in Philadelphia, researchers from Georgetown University Medical Center in Washington, D.C., announced that it may be possible for people with type 1 diabetes to grow their own insulin-producing cells, a breakthrough that could lead to a cure for the disease.

New scientifically-based family planning tool

A scientifically-based family planning tool developed by researchers from Georgetown University's Institute for Reproductive Health, a part of Georgetown University Medical Center (GUMC), is now available as an easy-to-use iPhone -, iPod touch- or iPad- application. iCycleBeads- is the first software application that enables a woman to plan or avoid pregnancy easily and effectively, entirely through the information provided by the application.

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.

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.
