In-Vitro Fertilization Turns 30!

Happy 30th Birthday in-vitro fertilization! That’s right, it’s a big b-day for anyone conceived via IVF, especially Louise Brown, the world’s first IVF baby. Her parents, Lesley and John, had tried for nine years to have a child (sounds like fun), when they heard about experimental fertility research being conducted at Cambridge University. Physiologist Robert Edwards and gynecologist Patrick Steptoe were pioneering the “test-tube” baby and the Brown’s volunteered to try the controversial method. Three decades later, they’re among many IVF success stories. Over the years, 115,000 babies have been born in the U.S. alone thanks to IVF and just this summer, the fertility miracle helped a 70-year old woman conceive in India! As for Louise, who works as a shipping company administrator, she is a mother herself, to a healthy 18-month-old boy, which she was able to conceive naturally. Her younger sister Natalie Brown is also a notable achievement — she was the first IVF baby to give birth and she too was able to conceive without medical aid. Needless to say, the Brown kids are so grateful to the groundbreaking scientists that they consider them to be their granddads. And thanks to them, now everyone can have eggs scrambled, sunny side up, and even fertilized! [AFP]

    Obesity Can Cause Fertility Problems

    There’s been a dramatic increase in obesity in the U.S. over the past 20 years, and a new study from researchers in Scotland suggests obesity might be inhibiting men’s fertility. Past studies have shown that this is the case with women, and this new study, which looked at sperm samples from 5,000 men and divided them into groups based on the Body Mass Index, found that those with a normal BMI (20 to 25) had higher levels of normal sperm than those who were overweight or obese. Underweight men also had fewer normal sperm, “but there were not many underweight men in Scotland,” said Ghiyath Shayeb, the lead researcher. He and his team have a couple ideas about what could cause the issues in overweight men, and they either think fat tissues influence the metabolism of sex hormones, or the increase in fat may cause a rise in body temperature and result in overheating. Sperm is best produced at a temperature two degrees cooler than the normal body temperature — who knew? [CBS News] Keep reading »

    Sexual Preference From A Fertility Gene?

    One of the questions in the nature vs. nurture regarding homosexuality is if homosexuality is hereditary, and those in same-sex relationships can’t reproduce, why hasn’t homosexuality disappeared? A new Italian study might explain part of this. According to findings from the University of Padova in Italy, homosexuality in males might be caused by the same genes that increase fertility in females. This would mean that in the same family, if a male inherited this gene, he would be gay, and if a female inherited this gene, she would be more fertile and possibly give birth to more babies than normal, making up for her brother’s lack of offspring and passing on the gene. Now, this conclusion seems to make sense for gay men, but not for lesbians, and the researchers think there’s an entirely different explanation for that. [LiveScience] Keep reading »

    Girl Must Decide Whether To Use Mother’s Eggs Before She’s 18

    This is a strange and sad story. A ten-year-old girl in England has Turner syndrome, a condition that generally causes infertility because an X chromosome is missing. When the girl was 7, her mother had some eggs harvested so that if her daughter wanted, she could have a child that would be related to her (it would actually be her half-sister or half-brother) and not have to wait for ages to receive a donor egg. The problem is that egg-freezing laws only allow the storage of an egg for 10 years, so before the girl turns 18, she has to decide whether or not she wants to conceive a baby made from her mother’s egg right then. She would have to get pregnant before she can vote, and she probably wouldn’t have a guy in her life who would want to be the father of her children! Members of Parliament and doctors are urging ministers to change the law because IVF legislation hasn’t been updated in 18 years. Her best option would be to have the eggs fertilized by donor sperm and then frozen, which would buy her at least another 10 years before she’d have to get implanted with an embryo.

    Grow Your Own Baby

    It’s alive, it’s aliiiiiiive! German scientists have successful inseminated rats with Franken-sperm, the first lab grown man-juice. Genetics researchers at the University of Goettingen have developed fetuses through embryonic stem cells. Which means if they can transfer this technology to humans, getting pregnant could come self-contained in a chick’s package with no male necessary. While this process won’t give men a biological tie to the child, it could conceive one from two women, using the stem cells from one lady and the egg from the other. Amazing! The process is still a little shaky, as only 12 out of 65 mice eggs were actually fertilized, and of those, seven died within five months of birth. So, the docs are working out the kinks in the faux-sperm system and a team is even going to England to begin research with human stem cells, since Germany has laws preventing mad scientists from using people parts that way. Dr. Wolfgang Engel is hopeful and promises, “If it works in the mouse, I’m sure it will also work in the human.” [The Sydney Morning Herald]
