Cisgender men produce sperm in the testicles. It's from here that these male reproductive cells are released to inseminate the eggs women produce. Duncan says that repeated exposure to higher temperatures, such as those found in saunas, do inevitably have some effect on how much sperm is made by them. Testicles are located outside the body because they work better when they're cooler. If you're incubating them in a sauna then they don't work quite as well.
About one in seven couples in the UK will have difficulty conceiving, and about one in eight known pregnancies will end in a loss. As many as 29% of low-risk pregnancies will experience unforeseen complications.
Academia can be incredibly, overwhelmingly, demanding. Many feel that they have to dedicate all their time and energy to establishing and sustaining a successful career. But many don't want an all-encompassing career. And there are profound parts of life that can get pushed to the sidelines by these demands. And of course, for many, this includes parenthood. Today, we're going to speak with several researchers about the strain academia places on parents and those hoping to become parents.
The Trump administration really wants Americans to have more kids. President Trump, the self-proclaimed " fertilization president," has called for a new " baby boom." Transportation Secretary Sean Duffy says communities with big families should get more government funds. The on-again-off-again Trump ally Elon Musk, father of at least 14, has warned that "civilization will disappear" if we don't get busy.
Women in fertility treatment often feel they can't catch a break; the issues keep stacking up, cycle after cycle, complication after complication, diagnosis after diagnosis. It can feel like jumping through one hoop only to find three more waiting. Living in a state of fight or flight becomes the norm. What makes it even harder is that this pressure builds quietly over time.
While standard at-home ovulation tests predict fertile days by tracking estrogen and Luteinizing hormone (LH), they don't measure the hormone that confirms your ovulation, which is progesterone metabolite PdG. Inito allows women to measure estrogen, LH, progesterone (PdG), and FSH on a single test strip. Inito's AI models interpret these levels to reveal fertility hormone patterns, track fertile days, and confirm ovulation.
Business Insider has spent a year reporting on the true cost of a cancer diagnosis for young Americans. Cancer cases are rising for people in their 20s, 30s, and 40s, derailing finances and future plans at a pivotal stage of life. Dozens of patients have told us they're navigating relationships, fertility decisions, early parenthood, and career growth alongside treatment. They're paying medical bills and for all the unexpected costs along the way.
When my uncle was president, the fertility rate in this country was 3.5%. Today, it is 1.6%. The replacement rate, in other words the amount of fertility that you need in order to keep your population even, is 2.1%. We are below replacement right now. That is a national security threat to our country and we know why this is happening, and President Trump is addressing the root causes through his MAHA agenda of reducing endocrine disruptors, the exposure to chemicals that decrease fertility.
A breakthrough was announced last week in the world of fertility science. Scientists took skin cells from a human and used them to make egg cells. Yes, you read that right: skin made an egg. They then fertilised the egg with sperm by IVF and took it to the stage where it could be implanted into a womb.
One of the biggest platforms for Gen Z and millennials is TikTok. It's so popular that even my mother, who is in her 90s and doesn't own a smartphone, has heard of it-which gives TikTok the credibility it deserves. In the early days, TikTok was simple: short videos and fun lip-sync/dance skits. Nowadays, TikTok has become messier, more relatable, and closer to our lived experience-and those accounts attract the masses.
Through millennia of artistic expression and within the natural world, the ubiquitous spiral continues to mesmerize. In ancient traditions, the form often represents cycles. The triskele, for example, consists of three interlocking spirals thought to symbolize death, life, and rebirth or the triad of mind, body, and spirit. Spirals also emerge naturally in seashells and plants, sometimes linked to the concept of the golden mean, also known as the " divine ratio."
Men with higher sugar intake showed worse sperm health. The review evaluated data from healthy adult males and found that those consuming more than seven sugar-sweetened drinks per week saw a 22% drop in sperm concentration.
At first, she didn't notice, but as the months passed, the presence of her menses started to feel like a letdown. 'Everything looks fine! Your numbers are great. Just be patient, keep trying. Give it time,' was the rallying call from her OB/GYN.
"I started my womenswear label, properly, [when] I was about 14 or 15. I sold my first piece in Temple Bar when I was 15 and then opened my first stall when I was 16 - paid my way through school and college on that market."
