How Successful Is Surgical Sperm Retrieval in Klinefelter Syndrome?

open access: yesFrontiers in Reproductive Health, 2021
Klinefelter Syndrome (KS) is characterized by the presence of an extra X chromosome. It was first diagnosed in 1942 in a group of azoospermic men. KS is the most common chromosomal abnormality encountered in infertile men and accounts for more than 10 ...

Differences in Dynamics of Specific Antinuclear Antibodies and Their Susceptibility to B Cell–Targeting Treatment in Patients With Systemic Lupus Erythematosus

open access: yesArthritis &Rheumatology, EarlyView.
Objective The presence of antinuclear antibodies (ANAs) is characteristic for systemic lupus erythematosus (SLE). Antibody dynamics over time are thought to reflect the cellular source of ANAs and their therapeutic targetability. Anti–double‐stranded DNA (anti‐dsDNA) is the most prevalent and well‐studied of all ANAs, and fluctuations in anti‐dsDNA ...

Association of higher serum follicle-stimulating hormone levels with successful microdissection testicular sperm extraction outcomes in nonobstructive azoospermic men with reduced testicular volumes

open access: yesAsian Journal of Andrology
To investigate the impact of preoperative serum follicle-stimulating hormone (FSH) levels on the probability of testicular sperm retrieval, we conducted a study of nonobstructive azoospermic (NOA) men with different testicular volumes (TVs) who underwent

Sperm retrieval and fertilization in repeated percutaneous epididymal sperm aspiration [PDF]

open access: yesHuman Reproduction, 1998
Percutaneous epididymal sperm aspiration (PESA) for retrieval of spermatozoa for intracytoplasmic sperm injection (ICSI) is a new simplified technique in the treatment of men with obstructive azoospermia. There has been a fear that the PESA procedure, being blind, could cause damage to the epididymal duct system and make it impossible to retrieve ...

Efficacy of hormone pre‐treatment before ART to improve reproductive outcomes in infertile women with endometriosis: Network meta‐analysis of randomized controlled trials

open access: yesInternational Journal of Gynecology &Obstetrics, EarlyView.
Abstract Background Hormone pre‐treatment is still used before assisted reproductive technique (ART) in endometriotic women, but evidence supporting this recommendation is conflicting. Objectives To evaluate whether hormone pre‐treatment with gonadotropin‐releasing hormone (GnRH) agonists or progestogens could improve fertility in women with ...
