Sperm size ferret

Five domestic ferrets previously maintained for 12 weeks under a 16L:8D photoperiod were electroejaculated weekly for 15—65 weeks while continuing to be exposed to the prolonged light cycle. Two ferrets sustained spermatogenesis for 20 and 26 weeks, while sperm production in the remaining males either was sporadic or decreased, remained depressed and then increased to peak levels observed in other males. Regardless of the temporal spermatogenesis patterns within males, the number of electroejaculated spermatozoa with residual cytoplasmic droplets or abnormal acrosomes increased in all ferrets over time. Diluted ejaculates meeting artificial insemination criteria were deposited intravaginally or by transabdominal laparoscopy into the uterine horns of females treated 0 or 24 h earlier with 90 i.

Frozen Sperm Offer a Lifeline for Coral - The New York Times

A near-extinct species has been reinvigorated with fresh genetic material donated by a male that has been dead for 20 years. There may be a new hope for endangered species around the world. The critically endangered North American black-footed ferret population has been injected with fresh genetic material, thanks to a sperm donation made over 20 years ago. Although Scarface died 20 years ago, his genetic material had been kept in frozen storage against future need. Now, eight baby ferrets have been born -- some of which are Scarface's offspring. Their research was published last week in the journal Animal Conservation.

As corals go, Fungia is fairly reliable, usually releasing its sperm and eggs two days after the full moon. Today was Day 3. The recalcitrant corals sat outdoors in water-filled glass dishes, arranged in rows on a steel lab table.

University of Wyoming researchers studied inbred domestic ferrets and determined the mammals have low genetic diversity on a global scale, according to a paper recently published in Evolutionary Applications. This type of domestication can result in only a few individuals contributing to the gene pool of the domestic species, followed by a further reduction in genetic diversity when animals are bred for human-desired traits. Without genetic diversity, animals are at risk of genetic disorders and disease. Additionally, the mechanism for increasing cancer rates in pet ferret populations is currently unknown.
