Paterna Biosciences, a startup based in Utah, says it has successfully produced functional human sperm from stem cells in a laboratory setting. The company used this lab-grown sperm to create visibly healthy-looking embryos. The achievement could one day assist men with specific infertility issues in having biological children.

Paterna Biosciences announced that it has identified the precise instructions required to transform sperm-making stem cells into normal, mature sperm. This process marks a significant step in lab-based reproduction techniques, according to the company. The Utah-based firm claims the resulting sperm is functional and capable of fertilization, as demonstrated by the embryos produced in their experiments. The embryos appeared healthy under visual inspection, though further testing for viability remains ongoing. This development targets infertility challenges faced by men, potentially offering new options for biological parenthood. Paterna Biosciences positions the technique as a potential solution for certain types of male infertility, building on advances in stem cell research. No independent verification of the results has been detailed yet, but the startup's claims highlight progress in biotech fertility solutions.

보건부 전문가 패널이 파킨슨병과 중증 심장병 치료를 위한 유도만능줄기(iPS) 세포 유래 재생 의료 제품 2개를 조건부로 승인했다. 이는 노벨상 수상 줄기세포 기술의 상용화에서 세계 최초 가능성을 나타낸다. 소규모 임상 시험에서 안전성과 추정 효능이 확인된 이번 승인은 7년 내 사후 시장 검증을 요구한다.

New 3D maps reveal early DNA structure in embryos

Researchers have discovered that DNA in newly fertilized eggs forms a structured 3D scaffold before the genome activates, challenging long-held assumptions. Using a new technique called Pico-C, scientists mapped this organization in fruit fly embryos. A related study shows that disrupting this structure in human cells triggers an immune response as if under viral attack.

Two gene-editing baby startups shut down after less than a year

R3 Bio proposes 'organ sacks' to replace animal testing

A billionaire-backed biotech startup, R3 Bio, is developing genetically engineered 'organ sacks'—whole organ systems without a brain—as an alternative to animal testing. This idea comes as the Trump administration phases out animal experimentation across the federal government. A cofounder states the long-term goal is to create human versions.

Bundestag strengthens rights of biological fathers

2026년 02월 26일 AI에 의해 보고됨

The Bundestag has passed a law making it easier for biological fathers to assert their paternity legally. The reform implements a ruling by the Federal Constitutional Court and lowers hurdles for unmarried fathers. The long fight of one father contributed to this success.

Prosecutors seek to charge clinic owners for reproductive exploitation

Prosecutors in Córdoba have requested to charge the directors of Fecundart and Nascentis clinics, a lawyer, and an administrative employee with the crime of “reproductive exploitation”. The investigation uncovers an alleged recruitment of vulnerable women seeking financial gain, under the false claim of an altruistic spirit, to build a multimillion-dollar business targeting infertile couples.
