Assessment of anti-sperm antibodies in couples after testicular sperm extraction

Clinical and Investigative Medicine, 2011
Purpose Testicular spermatozoa can be retrieved successfully by the testicular sperm extraction (TESE) procedure and used for intracytoplasmic sperm injection. Disruption in the blood-testis barrier can lead to the production of antisperm antibodies (ASA).

Effect of butorphanol in combination with xylazine during castration of calves: A randomised trial under field conditions

Veterinary Record, EarlyView.
Abstract Background In horses, cats and dogs, the opioid butorphanol has been proven effective in management of visceral pain and for peri‐ and postoperative pain relief. The aim of this study was to evaluate physiological responses and indicators of noxious stimuli when adding butorphanol to xylazine for sedation of bull calves during surgical ...

An engineered epididymal cell line provides a sustainable source of functional extracellular vesicles for in vitro sperm preservation: A multi‐omics and functional study

VIEW, EarlyView.
ABSTRACT This study investigated the function of epididymal extracellular vesicles (EVs) in overcoming sperm post‐testicular modification deficiencies. Although EVs derived from the epididymis play a crucial role in intercellular communication and molecular exchange, there is limited research addressing how EVs released by in vitro cultured epididymal ...

Sperm retrieval techniques in azoospermic patients: PESA, MESA, TESA, TESE and MICROTESE [PDF]

Einstein (São Paulo), 2009
Azoospermia is defined as the absence of mature spermatozoa in semen analysis after centrifugation. The causes of azoospermia may be related to spermatogenesis defects and classified as non-obstructive azoospermia, or to the obstruction of the efferent ...

Trends in the Use and Indications for Intracytoplasmic Sperm Injection Between 2005 and 2017: A State‐Wide Descriptive Cohort Analysis

Australian and New Zealand Journal of Obstetrics and Gynaecology, EarlyView.
ABSTRACT Background Intracytoplasmic sperm injection (ICSI) was first developed to overcome male factor infertility. ICSI has increased in uptake globally, including in cases where its use is non‐essential for fertilisation. Aims To identify temporal trends in the use of, and indications for ICSI in an Australian context.

MAFB is dispensable for the fetal testis morphogenesis and the maintenance of spermatogenesis in adult mice [PDF]

, 2018
The transcription factor MAFB is an important regulator of the development and differentiation of various organs and tissues. Previous studies have shown that MAFB is expressed in embryonic and adult mouse testes and is expected to act as the downstream ...

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.
