Bệnh vô sinh ở nam giới có chữa được không?

sẽ có tinh trùng (của chính mình) từ in 3D...

Much of the woes (đau buồn, phiền muộn, nỗi thống khổ) and struggles (cuộc đấu tranh, chiến đấu) of starting a family center around women and their fertility (khả năng sinh sản) issues. But for a third of all heterosexual couples grappling with infertility, the problem lies squarely with the man. Faulty sperm (tinh trùng khiếm khuyết) tends to be the No. 1 culprit. Around 10 percent of infertile men (and 1 percent of all men) suffer from azoospermia (không có tinh trùng), a condition in which sperm is completely absent in the semen. While there are treatment options available, like medication (thuốc điều trị) or surgery (phẫu thuật), these methods aren’t an option for some men who can’t make sperm at all. So some scientists are instead turning to the world of 3D printing to solve azoospermia.

In a new study published March 16 in the journal Fertility and Sterility Science, Canadian researchers 3D-printed live and functional human testicular cells (tế bào tinh hoàn) for the first time ever. This accomplishment likely lays the groundwork for solving sperm-associated forms of male infertility in the future.

Azoospermia comes in two forms—obstructive and non-obstructive. The former has a simple fix: Surgeons unblock or create the tubes that carry sperm from the testes out to the rest of the male reproductive system.

But with non-obstructive azoospermia—the most severe form of the condition—men aren't making sperm at all, and that could be due to many different reasons, some of which can be genetic like Klinefelter syndrome (where less testosterone is made because there’s an extra X chromosome) or hypogonadotropic hypogonadism (không dậy thì, where puberty is delayed or completely absent). Solving this problem first required understanding what was happening deep down at the cellular level.
