Severino Antinori

Severino Antinori is a biology topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Severino Antinori rather than just read about it. In short: Severino Antinori (born 6 September 1945 in Civitella del Tronto) is an Italian gynecologist and embryologist. He has publicly taken controversial positions over in vitro fertilisation (IVF) and human cloning.

Key takeaways

  • Severino Antinori belongs to biology; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Severino Antinori to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Severino Antinori from memory before moving on to harder problems.

Reference excerpt

Severino Antinori (born 6 September 1945 in Civitella del Tronto) is an Italian gynecologist and embryologist. He has publicly taken controversial positions over in vitro fertilisation (IVF) and human cloning. On 13 May 2016 Antinori was arrested and accused of kidnapping a woman, and stealing her ovules. He began his career interested in veterinary biology. He studied at the University of Rome La Sapienza, graduating in 1972 with a degree in medicine. Initially he worked in gastroenterology, but following a lecture by Patrick Steptoe he re-trained in obstetrics and gynecology, moving into reproductive and infertility work from 1978. He set up his own clinic in Rome in 1982. In 1986, he pioneered the use of the ICSI (intracytoplasmic sperm injection) process in Italy. From 1989 he extended IVF to women who had passed the menopause. In 1994 he assisted Rossana Della Corte, aged 63, in becoming pregnant. She became one of the oldest women in history to give birth. In May 2006 it was announced that 62-year-old East Sussex child psychiatrist, Patricia Rashbrook, was seven months pregnant after being treated by Antinori, who said that 62 or 63 was the upper limit for IVF in healthy women. He commented that he would only consider couples with at least 20 years' life expectancy left for fertility treatment. Josephine Quintavalle, from Comment on Reproductive Ethics (CORE), accused Rashbrook of selfishness and said it would be extremely difficult for a child to have a mother who is as old as a grandmother. In May 2009, after it was announced a 66-year-old woman was pregnant he criticised her decision saying that he felt she was too old and may not live long enough to raise her child.

Human cloning Antinori publicised his interest in human cloning from 1998; working with Panayiotis Zavos he argued in favour of cloning as an opportunity for infertile couples, who cannot use other methods. Genetic material from the father would be injected into an egg, which would then be implanted into the woman's womb to grow. The resulting child would, in theory, have exactly the same physical characteristics as the father. Antinori told an Italian newspaper that more than 1,500 couples had volunteered as candidates for his research programme. In November 2002, Antinori announced that he had successfully used cloning to induce pregnancy in three women, with the birth of the first child expected in January 2003. He refused to give the identities of the women or details of where they lived, and mainstream scientists and doctors expressed scepticism about his claims. On Thursday 25 October 2001, the BBC aired its Horizon programme in which Antinori and Zavos were the vocal proponents of human cloning. They promised they would produce the first human clones "within a year". The claim was refuted by Professor Lorraine Young of the Roslin Institute following her pioneering work with Doctor Ian Wilmut which culminated in the creation of Molly and Dolly, the worlds first cloned mammals. Young had discovered that the reason cloning was an inherently flawed technique was due to the process scrambling the positioning of DNA-associated methyl molecules which controlled the timing of DNA expression. Young warned Antinori and Zavos that they had "no understanding" of the issues and were "missing everything" with regard the fidelity of a repeatable cloning process. She further predicted that cloning was a technology that may never be successfully harnessed. Antinori and Zavos failed to heed the warnings of Professor Young and other specialists, and as of May 2020 have failed to lend credence to their claim of having been successful in cloning a viable mammalian embryo.

Charges of egg theft

In 2016, Antinori was arrested on suspicion of stealing eggs by removing them from a patient's ovaries without her consent under the guise of performing a procedure on her to remove an ovarian cyst. He had recently hired a Spanish nurse at his clinic, and then diagnosed her with an ovarian cyst for the sole purpose of harvesting her eggs without her knowledge. Antinori was arrested at Fiumicino airport, charged with aggravated robbery and causing personal injury, and placed under house arrest.

Worked examples

Example 1 — a first encounter with Severino Antinori

Start with the simplest possible case. Write down what Severino Antinori claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In biology, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Severino Antinori before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Severino Antinori ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Severino Antinori

In research
Severino Antinori appears in biology research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Severino Antinori in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Severino Antinori is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1945 births, Embryologists, Italian gynaecologists, so understanding it makes those chapters shorter.
In everyday life
Look for Severino Antinori outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
