Obstructive and Non-Obstructive Azoospermia

, 2012
Azoospermia is defined as the complete absence of spermatozoa upon examination of the semen [including capillary tube centrifugation (CTC), strictly confirmed by the absence of spermatozoa issued in urine after ejaculation]. The presence of rare spermatozoa (

Correlation of serum FSH and rate of testicular sperm retrieval in non-obstructive azoospermia

Indian Journal of Endocrinology and Metabolism, 2023
Background: Sperm retrieval from men with azoospermia has evolved in recent times, providing patient hope for fulfilling their dream of having their own genetic child through testicular sperm extraction followed by intracytoplasmic sperm injection (TESE ...

IGFBP5 Restores Endometrial Receptivity and Rescues Implantation Failure in Polycystic Ovary Syndrome

Advanced Science, EarlyView.
Impaired endometrial receptivity contributes to the poor pregnancy outcomes in women with PCOS. The authors found that decreased endometrial IL‐22 levels and disrupted STAT3‐IGFBP5 signaling pathway contributed to impaired endometrial receptivity. Supplementation with IL‐22 or IGFBP5 exerts a protective effect on implantation failure in PCOS‐like mice,

Azoospermia: a Genomic Review [PDF]

, 2017
Azoospermia or the absence of sperm in semen is one of the sperm disorders that results in male infertility. There are two types of azoospermia, the first one isazoospermia caused by obstruction of the vas deferens (obstructive azoospermia) and the ...

Human spermatogenic failure purges deleterious mutation load from the autosomes and both sex chromosomes, including the gene DMRT1 [PDF]

, 2013
Gonadal failure, along with early pregnancy loss and perinatal death, may be an important filter that limits the propagation of harmful mutations in the human population.

Testicular histopathology and its association with germ cell numbers, serum concentrations of reproductive hormones, and semen quality

Andrology, EarlyView.
Abstract Background It is well‐established that spermatogenesis, semen quality, and reproductive hormones are interlinked. It is, however, less well‐described how various specific testicular histopathologies are linked to reproductive hormones and semen quality.

The use of deidentified organ donor testes for research

Andrology, EarlyView.
Abstract Our knowledge of testis development and function mainly comes from research using mammalian model organisms, primarily the mouse. However, there are integral differences between men and other mammalian species regarding cellular composition and expression profiles during fetal and post‐natal testis development and in the mature testis ...
