First discovery of sperm
Human sperm were first discovered by a student of Antonij van Leeuwenhoek in 1677 in the city of Delft . The name of the student is not known for certain: he is variously written up as Ludwig Hamm, van Hamm or von Hammen. According to some writers he is a Dutchman, to others a German. One day he brought to the acknowledged master of microscopy, Leeuwenhoek, a bottle containing semen and pointed out that small animals could be seen moving about in the ejaculate. Van Leeuwenhoek went on to study the seminal emissions from a wide range of sick and healthy men; in the semen of them all the odd creatures could be detected. He described his findings to the Royal Society in London
I have seen so excessively great a quantity of living animalcules that I am much astonished by it. I can say without exaggeration that in a bit of matter no longer than a grain of sand more than fifty thousand animalcules were present, whose shape I can compare with nought better than with our river eel. These animalcules move about with uncommon vigour and in some places clustered so thickly together that they formed a single dark mass. After a short time they separated. In fine, these animals astonished my eye more than aught I had seen before.
Of course at the end of the seventeenth century there was still a mystery as to what sperm actually were. Some thought them to be parasites in the seminal fluid - and saliva and urine and other bodily secretions were quickly examined in the search for more sperm. Others thought them coagulating agents.
A student of Leeowenhoek (below, with his microscope) is credited with the first discovery of sperm. Right up to the end of 17th c., male spermatozoa was surrounded by mystery. Right, as it was understood by Uartsoeher (1655 1725).
Sperm as a discovery
The first discovery of sperm was made by one student which name is not known exactly. He started to study semen as little animals moving quickly in the ejaculate. His first thought was that only sick men have it. But it was found that sperms are also present in healthy men’s ejaculate. The student described them like living beings moving about with a very high speed. In some places they are thickly together and form a single dark mass. But then they separate.
You can imagine that in the seventeenth century such discovery was extraordinary thing. All scientists started to examine sperm and their thoughts were very different. Only in the nineteenth century the sperm was called fertilizing and coagulating agent.
As for the first sperm banks they are found in Iowa City and Tokyo , in 1964.
Most famous nymphomaniac in antiquity
Valeria Messalina of ancient Rome almost certainly wins this one; indeed her name (the "Messalina complex") has been used as a synonym for nymphomania. With her insatiable sexual appetities she acted as prostitute and seducer. She married Claudius when only sixteen; it has been speculated that she started an active sex life when she was thirteen or fourteen. If she fancied a man, Claudius would order him to submit to her whims: it was useful being married to an emperor. Dio Cassius has declared that she kept her lustful husband well supplied with housemaids for bedfellows. She often enjoyed herself in the local brothel - female sexual enhancement.
First famous nymphomaniac
The first and most famous nymphomaniac in antiquity was Valeria Messalina. Her name is also used as a synonym for nymphomania. She started her sex life at the age of thirteen or fourteen and married Claudius when she was sixteen-years-old. She acted as a prostitute. When she liked somebody her husband ordered him to become her lover. Also Valeria Messalina often visited the local brothel.
Youngest sexually potent male
The earliest ejaculation remembered by any of the "apparently normal males" surveyed by Kinsey was at the age of eight: this age was noted by three males. The history was also taken of one unusual boy, a Negro interviewed when he was 12, who reckoned he first ejaculated at the age of six. A clinician had diagnosed the boy as "idiopathically precocious in development." In the literature- Kinsey quotes three cases - there are clinical instances of still younger ages. Non-motile sperm have been detected in urine after prostate massage at four and half years. Kinsey opts for eight as the earliest reliably recorded ejaculation.
Earliest ejaculation
As for the youngest sexually potent male, it was the boy of eight years. The specialists call him “the apparently normal male”. But the history knows the twelve year boy who started to ejaculate at the age of six. This phenomenon is called "idiopathically precocious in development." Also, according to the medical literature there is the case when ejaculation occurred after prostate massage at four and half years.
