Conventional multiple or microdissection testicular sperm extraction: a comparative study.
BACKGROUND Testicular sperm extraction (TESE) with ICSI is becoming the first-line treatment for non-obstructive azoospermia (NOA). Recently, the sperm retrieval rate (SRR) by microdissection TESEExpand

Prediction of successful outcome of microdissection testicular sperm extraction in men with idiopathic nonobstructive azoospermia.
PURPOSE Microsurgical techniques in testicular sperm extraction can improve sperm retrieval in patients with nonobstructive azoospermia (NOA). However, spermatozoa retrieval rates have still beenExpand

Primary structure of the human follistatin precursor and its genomic organization.
Follistatin is a single-chain gonadal protein that specifically inhibits follicle-stimulating hormone release. By use of the recently characterized porcine follistatin cDNA as a probe to screen aExpand

Follistatin gene expression in the ovary and extragonadal tissues.
Follistatin is a glycosylated single-chain protein originally isolated from porcine follicular fluid. It specifically inhibits the secretion of FSH from the pituitary. We have now isolated andExpand

Salvage microdissection testicular sperm extraction after failed conventional testicular sperm extraction in patients with nonobstructive azoospermia.
PURPOSE TESE is considered the best procedure for identifying a tubule for spermatozoa retrieval. This technique improves the SRR to around 50%. However, it has been unclear whether it is useful inExpand

Clinical comparison of successful and failed microdissection testicular sperm extraction in patients with nonmosaic Klinefelter syndrome.
OBJECTIVES Testicular sperm extraction (TESE), together with intracytoplasmic sperm injection, has become the treatment of choice for patients with nonobstructive azoospermia related to nonmosaicExpand

Chromosomal variants among 1790 infertile men
Abstract Background: The largest cytogenetic survey involving infertile men was undertaken to clarify whether chromosomal abnormalities, including autosomal abnormalities, affect semen qualities.

Mapping of eight testis-specific genes to mouse chromosomes.
We previously identified eight testis-specific genes using antibodies raised against testicular germ cells. They are expressed during spermatogenesis and are presumed to be involved in testicularExpand

Ejaculated spermatozoa in patients with non‐mosaic Klinefelter’s syndrome
Background : Non‐mosaic Klinefelter patients are generally azoospermic and there is no therapy to improve the spermatogenesis. Some patients have a few spermatozoa in their ejaculates, which can beExpand

Comparative study on evaluation methods for serum testosterone level for PADAM diagnosis
The International Society for the Study of the Aging Male (ISSAM) recommends that a diagnosis be based on a patient's total testosterone (TT), calculated free testosterone (cFT), or calculatedExpand
