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.

Advisory Committee on Immunization Practices supports the permissive use of GARDASIL

Merck & Co., Inc. announced today that the U.S. Centers for Disease Control and Prevention’s (CDC’s) Advisory Committee on Immunization Practices (ACIP) supports the permissive use of GARDASIL® [Human Papillomavirus Quadrivalent (Types 6, 11, 16 and 18) Vaccine, Recombinant] for boys and young men ages 9 to 26, which means that GARDASIL may be given to males ages 9 to 26 to reduce the likelihood of acquiring genital warts at the discretion of the patient's health care provider.

Proteins play vital role in transferring human genetic code from one cell to another

A Florida State University College of Medicine researcher has solved a century-old mystery about proteins that play a vital role in the transfer of the human genetic code from one cell to another. The discovery could lead to finding new ways to help the body fight a variety of diseases, including cancer.

Repros announces results of its Androxal efficacy study for secondary hypogonadism

Repros Therapeutics Inc. today announced results from an exploratory, efficacy and safety study of its oral investigational product, enclomiphene citrate (Androxal®), in men with secondary hypogonadism who were receiving testosterone replacement treatment. Secondary hypogonadism is a deficiency state in which the male hormone testosterone goes below the normal range, even in aging men, due to inadequate stimulation of the testes by the pituitary.

Brdt protein in developing sperm cells direct tight re-packaging of sperm DNA

In the quest for speed, olympic swimmers shave themselves or squeeze into high-tech super-suits. In the body, sperm are the only cells that swim and, as speed is crucial to fertility, have developed their own ways to become exceptionally streamlined. Scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg and Grenoble, the Institut de Biologie Structurale (IBS) and the Institut Albert Bonniot, both also in Grenoble, have been studying the secrets of speedy sperm.

Children with minimal change nephrotic syndrome can be treated with prednisone

A kidney condition that can arise in children and was until recently believed to disappear after puberty may persist into adulthood and cause significant long-term complications, according to a study appearing in an upcoming issue of the Clinical Journal of the American Society Nephrology (CJASN). The findings indicate that better treatment options are needed for children with the disorder, called minimal change nephrotic syndrome.

NICE updates its guidance on hysteroscopic sterilization

Conceptus, Inc., developer of the Essure procedure, the first proven non-incisional permanent birth control method available, today announced that the National Institute for Health and Clinical Excellence (NICE) in the United Kingdom has updated its guidance on hysteroscopic sterilization to support the use of the Essure permanent birth control procedure.

Link between a key molecular player and human chromosomal birth defects established

Using yeast genetics and a novel scheme to selectively remove a single protein from the cell division process called meiosis, a cell biologist at The Florida State University found that when a key molecular player known as Pds5 goes missing, chromosomes fail to segregate and pair up properly, and birth defects such as Down syndrome can result.

Female insects control sperm storage to rule out genetic disorders

Scientists have found new evidence to explain how female insects can influence the father of their offspring, even after mating with up to ten males. A team from the University of Exeter has found that female crickets are able to control the amount of sperm that they store from each mate to select the best father for their young.

Tel Aviv University biologist discusses about human fertility

About 10% of all couples hoping for a baby have fertility problems. Environmentalists say pollution is to blame and psychiatrists point to our stressful lifestyles, but evolutionary biologist Dr. Oren Hasson of Tel Aviv University's Department of Zoology offers a different take. The reproductive organs of men and women are currently involved in an evolutionary arms race, he reports in a new study. And the fight isn't over yet.

Y chromosome may be responsible for a range of sex disorders

The unique mechanism behind the evolutionary survival of the human Y chromosome may also be responsible for a range of sex disorders, from failed sperm production to sex reversal to Turner Syndrome.
