Dr Bertold Wiesner A UK sperm donor has fathered 600 children at his infertility clinic.
Dr.Wiesner is reputed to be a Pioneer in the field of Infertility Treatment.he reported to have been responsible for the birth of 600 Children.
Let us take the mean Ejaculation Value of 5 millilitres.
So Dr.Wiesner has used up 3000 millilitres for fathering the 600 children.
That is 3 ,THREE Litres!
“The force and amount of semen that will be ejected during an ejaculation will vary widely between men and may contain between 0.1 and 10 milliliters.[10] (By way of comparison, note that a teaspoon is 5 ml and a tablespoon holds 15 ml.) Adult semen volume is affected by the time that has passed since the previous ejaculation; larger semen volumes are seen with greater durations of abstinence. It is not clear whether frequent ejaculation increases,[11] reduces[12] or has no effect[13] on the risk of prostate cancer. The duration of the stimulation leading up to the ejaculation can affect the volume.[14] Abnormally low volume is known as hypospermia. One of the possible underlying causes of low volume or complete lack of semen is ejaculatory duct obstruction. It is normal for the amount of semen to diminish with age.”

Barry Stevens, a documentary film-maker from Canada, and David Gollancz, a London-based barrister, say that on the basis of recent DNA tests Dr Bertold Wiesner made up to two-thirds of the clinic’s total sperm donations.
In 2007, DNA tests on 18 people who had been conceived at the clinic between 1943 and 1962 showed that 12 of the group – two-thirds – were Dr Wiesner’s children, The (London) Sunday Times reported.
Using these results, Mr Stevens and Mr Gollancz believe that Wiesner, who died in 1972, must have fathered as many as 600 children.
“A conservative estimate is that he would have been making 20 donations a year,” Mr Gollancz said.
“Using standard figures for the number of live births which result, including allowances for twins and miscarriages, I estimate that he is responsible for between 300 and 600 children.”
That figure would dwarf previous records. Last year it emerged that one anonymous sperm donor in the US had fathered 150 children.
The Barton Clinic, set up by Dr Wiesner, a biologist, and his wife Mary Barton, a doctor, has long been surrounded by controversy because it was believed to have used sperm donations drawn from their small circle of academic friends.
In 2001, it was revealed Derek Richter, a neuro-chemist, fathered more than 100 of the clinic’s children.
After the British Medical Journal published an article from the couple on their work in 1945, a peer in Britain’s House of Lords denounced their activity as “the work of Beelzebub” and the then Archbishop of Canterbury called for their clinic to be outlawed.
