 Our Stolen Future: Emerging science on sperm maladies
This procedure, while appropriate for the medical goals of a sperm donation or storage clinic, would invalidate the use of these data in trend analysis.
Suppose such a study identified significant differences in sperm density between geographic areas that cannot be explained by host factors (such as age and ethnicity) and personal behaviors (such as drinking and smoking)?
in their meta-analysis of sperm count changes in men from samples around the world (mostly from developed countries).

Semen, the fluid that carries the sperm, was analyzed using criteria accepted by the World Health Organization (WHO).
Her results were similar to what others found with Chinese men, but differ significantly from a French study.
"It's very difficult to compare sperm counts from one laboratory to the other," says Harry Fisch, MD, a urology professor at Columbia-Presbyterian Medical Center in New York.

 Genius Sperm Bank Information
Fairfax Cryobank is a traditional sperm bank that has a program, started in April, 1999, for clients seeking donors with a higher level of education.
Over the past decade, sperm banks have appeared around the world catering to women clients who care mostly about the physical appearance of the sperm donor.
The Repository for Germinal Choice in Escondido, California, was a sperm bank which selected sperm donors based mainly on scientific achievements and publications, and also on other criteria such as artistic and musical ability and various health criteria.

This damage may indicate that sperm whales are susceptible to decompression sickness and sudden surfacing could be lethal to them.
In contrast to the smooth skin of most other large whales, the skin on the back of the Sperm Whale is usually knobbly and has been likened to a prune by whale-watching enthusiasts
However, the brain is not large relative to body size.

 Sperm Whales
The Sperm whale has a robust body with corrugations in the skin giving it a shrivelled prune-like appearance.

 Wonders of the Seas: Sperm Whales
In fact, we know a lot about what Sperm whales don't do--but not very much else.
Sperm whales can most likely determine the size, direction and distance of prey, which helps them hunt deep below where there is no light.
For all we know, both theories could be right.

Your child will grow up knowing that the main reason their donor helped you bring children into your family was that he wanted children in his own life, even though he did not want to raise children himself.
Because the donor will know the 3 other biological mothers of his offspring, through the donor, you could be connected to other Lesbian households who are raising the biological half-siblings of your child.

 News in Science - Do sperm have a nose for eggs? - 28/03/2003
Hundreds of olfactory, or odour, receptors have been discovered but, despite their name, they are often found in body tissues other than the sensory neurons of the nose and are coupled to complex biochemical signalling pathways.
Human sperm have the ability to 'smell' and may even have a special receptor that allows them to sniff out an egg and make a beeline for it, a new study has found.
The researchers also identified an antagonist compound, called undecanal, that seems to inhibit the sperm response to the bourgeonal signal.

 SPERM WHALE
Sperm whales produce ambergris, a dark, waxy substance (related to cholesterol) that is produced in the lower intestines, and is sometimes found containing squid beaks.
Sperm whales use echolocation to catch their prey in the dark oceanic depths.
The meaning or purpose of lobtailing is unknown, but may be done as a warning to the rest of the pod or as some other type of communication.

 sperm on Encyclopedia.com
In higher animals the sperm is produced in the testis of the male; it is much smaller than the ovum and consists primarily of a head, whose nucleus bears the hereditary material (see chromosome) of the male parent, and a slender whiplike process (flagellum), which provides the motility necessary for fertilization in a fluid medium.

 Sperm Whales (Physeter macrocephalus)
Sperm whales are very difficult to study because they spend most of their time in open water, away from coastlines.
These sounds may be used for communication, or possibly echolocation.
Sperm whales have huge heads (40% of the body length) and possess the largest brain of any creature that has ever lived on Earth.

 Sperm Whale
The sperm whale, or cachalot, is one of the cetaceans, a group of marine mammals whose ancestors were probably land animals.
Approximately 700,000 sperm whales are thought to exist.
Sperm whales have no teeth in their upper jaw, but 60 in the lower jaw; these are about 20 cm long, weighing up to 2 or 3 kg each.

 MedlinePlus Medical Encyclopedia: Sperm
The male reproductive system creates sperm that is manufactured in the seminiferous tubules within each testicle.
The tip of the sperm head is the portion called the acrosome, which enables the sperm to penetrate the egg.
The head of the sperm contains the DNA, which when combined with the egg's DNA, will create a new individual.
