Takehiko Ogawa
is a Japanese urologist and developmental biologist, known for his pioneer research on In vitro spermatogenesis, ''in vitro'' spermatogenesis. He is Professor of Proteomics at Graduate School of Medical Life Science, Yokohama City University. Contribution In 2011, Ogawa and his colleagues succeeded to produce functional sperm from spermatogonial stem cells with the testis of mouse using an organ culture method, which was the first demonstration of mammalian. The result could change views about fertility and spermatogenesis and result in new diagnostics for male infertility as well as treatment and follow-up of patients with cancer. In 2014, his research group reported that a sample of frozen testicle has been used to produce live offspring in experiments on mice, and this breakthrough could have important implications for boys with cancer who become infertile due to chemotherapy treatments. Biography Ogawa received his M.D. in 1985 and his doctorate in Pathology in 1989 from Yokoha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Urologist
Urology (from Greek οὖρον ''ouron'' "urine" and ''-logia'' "study of"), also known as genitourinary surgery, is the branch of medicine that focuses on surgical and medical diseases of the urinary-tract system and the reproductive organs. Organs under the domain of urology include the kidneys, adrenal glands, ureters, urinary bladder, urethra, and the male reproductive organs (testes, epididymis, vas deferens, seminal vesicles, prostate, and penis). The urinary and reproductive tracts are closely linked, and disorders of one often affect the other. Thus a major spectrum of the conditions managed in urology exists under the domain of genitourinary disorders. Urology combines the management of medical (i.e., non-surgical) conditions, such as urinary-tract infections and benign prostatic hyperplasia, with the management of surgical conditions such as bladder or prostate cancer, kidney stones, congenital abnormalities, traumatic injury, and stress incontinence.
