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.

FUJIFILM Irvine Scientific Launches Heavy Oil for Embryo Culture: Optimized Protection for the IVF Laboratory

FUJIFILM Irvine Scientific, Inc., a world leader in the innovation, development, and manufacture of cell culture media and assisted reproductive technologies (ART), today announced the launch of its Heavy Oil for Embryo Culture, a sterile mineral oil with an optimal weight viscosity that provides the ideal balance between ease of use and protection.

Researchers develop new SERS method for active capture of target molecules

Recently, a team led by Prof. Yang Liangbao from Hefei Institutes of Physical Science, Chinese Academy of Sciences used the nano-capillary pumping action to automatically capture the target molecules into a smaller gap and achieve highly sensitive Surface-Enhanced Raman Spectroscopy (SERS) detection by constructing a multilayer nanoparticle film to form a natural gap of less than 3 nm between the layers.

DNA may act as nutritional source for E. coli

Findings of a new experiment could be helpful in understanding how DNA acts as a nutrient for gut bacteria, and its impact on the health of the host.

Newly characterized stem cell self-renewal factor enables continuous sperm production

Unlike women, who are born with all the eggs they'll ever have, men can continue to produce sperm throughout their adult lives. To do so, they require a constant renewal of spermatogonial stem cells, which give rise to sperm.

Ancestral molecule from bacteria-like cells may offer evolutionary insight on sexual reproduction

A study from Karolinska Institutet in Sweden, among others, presents the theory that egg-sperm fusion, a crucial feature of sexual reproduction in plants and animals, may have originated from an ancient form of genetic exchange that involved the fusion of bacteria-like microorganisms called archaea.

Commercial DNA databanks transform how people involved in donor conception seek information

People conceived by sperm and egg donation, as well as their parents and donors, are making use of commercial genetic DNA testing in a variety of ways little considered in earlier reports, according to the interim results of a qualitative study presented here at ESHRE's 38th annual meeting in Milan.

Biologists shed light on the evolution and consequences of selfish genetic elements

The human genome is littered with "selfish genetic elements," which do not seem to benefit their hosts, but instead seek only to propagate themselves.

"Selfish chromosomes" explain why most human embryos die very early on, study suggests

New research by a scientist at the Milner Center for Evolution at the University of Bath suggests that "selfish chromosomes" explain why most human embryos die very early on. The study, published in PLoS, Biology, explaining why fish embryos are fine but sadly humans' embryos often don't survive, has implications for the treatment of infertility.

Study suggests a potential tool to help improve fertility treatment outcomes

Screening sperm may help identify potentially harmful new genetic mutations and help fertility specialists prevent them from being passed on to offspring, shows a preliminary study published in eLife.

Study highlights the non-inferiority of frozen sperm for intrauterine insemination treatments

Patients having intrauterine insemination for fertility treatment can be reassured that the use of cryopreserved sperm instead of fresh is not associated with inferior outcomes.
