New microscopy may identify best sperm cells: Cutting-edge innovation pinpoints top candidates for assisted reproductive technology
New microscopy may identify best sperm cells: Cutting edge innovation pinpoints top candidates for assisted reproductive technology.
: New microscopic technology promises to be a game-changer in the field of reproductive assistance. A team of scientists has devised a new method of microscopy allowing scientists to perform clinical sperm analysis for in vitro fertilization without the use of staining, which can affect the viability of sperm samples.
IVF baby born from world’s oldest sperm
Little Xavier
Powell has been dubbed the world’s oldest baby after he was born from sperm
that was harvested nearly 23 years ago.
The baby boy
recently received the title from the Guinness World Book of Records, which said
that he was conceived at a fertility group in Queensland, Australia, on Sept 24
last year.
According to The Mirror UK, Xavier was born on June 17 this year to
Australian couple Alex Powell and Vi Nguyen via in-vitro fertilisation (IVF).
When he was
15 years old, Mr Powell was diagnosed with a rare type of cancer that affects
the lymphatic system – Hodgkin’s lymphoma.
Although he
was only a teenager at the time, his stepmother had advised him to freeze his
sperm before undergoing chemotherapy.
Sperm cells
can be easily damaged by chemotherapy as it kills cells that divide rapidly, an
article by the American Cancer Society explains.
The treatment
may also reduce the number of sperm cells, reduce their quality, and cause the
cancer patient to suffer from infertility.
After what Mr
Powell described as “an awkward session” at the sperm bank, a sample of his
semen remained frozen in the facility for over two decades.
He
subsequently made a full recovery from cancer and later met his wife.
The couple
decided to have a child through IVF in late 2013, and spent nearly a year as
well as half of the frozen sperm before getting pregnant with Xavier.
On his son’s
birth, Mr Powell said in an interview with 9News: “For me, it’s that sort of
feeling in life you want to relive every moment if you can.”
He added that
they might try for a second child using the same method.
Meanwhile, a
baby girl born in the United States in 2009 is believed to have been the
titleholder of ‘World’s oldest baby’ before Xavier’s arrival.
ABC News
reported that she was born 22 years after her father Chris Biblis froze his
sperm while battling leukaemia in 1986.
According to
medical experts, sperm frozen at -196 degrees Celsius can be stored and used
after an indefinite period of time.
In a report
by The Guardian UK, Alan Pacey, an andrologist at Sheffield University
elaborated: “There’s very little happening at the cellular level. There’s no
enzymatic activity, no DNA transcription and everything metabolic is switched
off.”
