Fertilisation, both natural and by assisted reproduction techniques (ART), needs the dual support of the sperm not only for the messages it carries but also for being as a messenger cell and carrier of these messages. Nevertheless, in the era of intracytoplasmic sperm injection (ICSI) though, ...
In mammals, these gametes are the sperm and egg that eventually fuse to form the developing zygote. In yeast, meiosis is coupled to the process of sporulation, whereby the four haploid nuclei are retained within the confines of a single cell known as the ascus. The resultant spores that ...
Learn and discuss meiosis in spermatogenesis, seminiferous tubules, sperm cell precursors, and the anatomy of sperm. Related to this QuestionWhat are stem cells and what can they be used for? What are the major components of a sperm cell and what roles do they have in reproduction? Give exam...
What is the term for a male reproductive cell? What is the scientific name for sex cells? What do sex chromosomes do in somatic cells? How many sex cells are made from one body cell? Where are sex cells produced? The male gamete is called ___. In which structure do sperm cells devel...
The inheritance of the centrosome during human fertilization remains mysterious. Here we show that the sperm centrosome contains, in addition to the known typical barrel-shaped centriole (the proximal centriole, PC), a surrounding matrix (pericentriolar
Model fish species such as sticklebacks and zebrafish are frequently used in studies that require DNA to be collected from live animals. This is typically achieved by fin clipping, a procedure that is simple and reliable to perform but that can harm fish
The cells were placed in a gelatin-coated 12-well plate at a cell density of 2 × 105 cells/ml and incubated for 16–24 h at 37 °C in a humidified incubator with 5% CO2. The somatic cells of the testis attached to the gelatin plate, and the germ cells did not. The floating ...

However, we discovered that the Ar mutants showed no difference in testicular morphology, except thearaKO males exhibiting hypertrophic testes filled with mature sperm, which correlated with their higher gonad/body weight ratio (gonadal-somatic index; GSI) (Fig.1c, d). We found that even inarD...
