1. Male fertility potential alteration in rheumatic diseases: a systematic review
ABSTRACT Background Improved targeted therapies for rheumatic diseases were developed recently resulting in a better prognosis for affected patients. Nowadays, patients are living longer and with improved quality of life, including fertility potential. These patients are affected by impaired reproductive function and the causes are often multifactorial rel

2. Effectiveness of sperm washing by discontinuous density gradient centrifugation to remove antibodies bound to the sperm membrane
OBJECTIVE: We evaluated the effectiveness of sperm washing using the discontinuous two-layer density gradient centrifugation method to remove antisperm antibodies attached to the sperm surface. METHOD: We prospectively enrolled sixty-six men with unexplained infertility who were seeking evaluation. Each patient delivered one semen specimen for the study. W

4. Evaluation of gonadal function in male patients with antiphospholipid syndrome / Avaliação da função gonadal em pacientes do sexo masculino com síndrome antifosfolípide
INTRODUÇÃO. A síndrome antifiosfolípide (SAF) é uma condição trombofílica autoimune associada a títulos elevados e persistentes de anticorpos antifosfolípides. Caracteriza-se por tromboses em diversos órgãos, incluindo os testículos. OBJETIVO. Realizar uma avaliação global da função gonadal em pacientes masculinos com SAF primária (SAFP) e

5. Minor sperm abnormalities in young male post-pubertal patients with juvenile dermatomyositis
The objective of the present study was to identify sperm abnormalities in young male patients with juvenile dermatomyositis (JDM). In 2005, 18 male JDM patients, diagnosed according to the criteria of Bohan and Peter, were followed at the Pediatric Rheumatology Unit and Rheumatology Division, of our Institution. Of the 18 males, 11 were pre-pubertal and 7 we

6. Influence of antisperm antibodies in the semen on intracytoplasmic sperm injection outcome
OBJECTIVE: The aim of this study was to analyze the influence of autoantibodies against spermatozoa present in the semen on the outcome of in vitro fertilization with intracytoplasmic sperm injection (ICSI). MATERIALS AND METHODS: We performed a retrospective analysis of clinical and laboratorial data from a six year-period ICSI cycles. Screening for the pre

7. Gonadal evaluation in male systemic lupus erythematosus / Avaliação da função gonadal em pacientes do sexo masculino com lúpus eritematoso sistêmico
Objective: To assess gonadal function in male systemic lupus erythematosus (SLE) patients. Methods: Thirty-five consecutive male SLE patients (American College Rheumatology criteria) were prospectively evaluated for demographic, clinical features, previous and current treatment, urologic evaluation, testicular Döppler ultrasound, hormone profile, semen anal

8. Evolução e perfil dos anticorpos antiespermatozóides nos primeiros 180 dias em indivíduos vasectomizados / Evolution and profile of the antisperm antibodies during the first 180 days of the vasectomized individuals
The contraceptive method of vasectomy can be reversed, in certain circumstances, through surgical procedures; but the incidence of autoimmune antisperm humoral responses in some vasectomized individuals may impede attempts to restore fertility. In this context, investigations on the incidence and evolution of autoimmune responses in vasectomized individuals

9. Determinação da presença de anticorpos anti-espermatozoides no semen de casais submetidos a tecnicas de reprodução assistida
Antisperm antibodies (ASA) has been responsabilized as a well-stablished cause of male infertility. Conditions that disrupt the blood-testis barrier or changes in the female genital tract, could trigger its production. These ASA interfere in several steps of the fertilization, compromising the success of the assisted reproduction procedures. With the goal of

10. Antiidiotypic antibodies to sperm in sera of fertile women that neutralize antisperm antibodies.
The presence of antiidiotypic antibodies (ab-2) to sperm was investigated in the sera of fertile, infertile, and virgin women using sperm-specific anti-FA-1 monoclonal antibody Fab'.ab-2 were detected in 71% (17/24) of sera from fertile women and in none (0/12) of the sera from virgin females by the enzyme-linked immunosorbent assay, Western blot procedure,

11. Anti-sperm antibodies in homosexual men: prevalence and correlation with sexual behaviour.
The sera of 60 homosexual males were examined for the presence of antibodies to sperm using an indirect immunobead test (IBT). Six of 60 (10%) had antibodies of IgG isotype; in addition two of the six had antibodies of IgA isotype. The presence of antibodies was associated with the practice of unprotected receptive anal intercourse in the previous six months

12. Sperm-related antigens, antibodies, and circulating immune complexes in sera of recently vasectomized men.
Sera from 35 men were collected before and at timed intervals subsequent to vasectomy and examined for the presence of (a) antibody reactive with human spermatozoa, (b) sperm-related antigen, and (c) circulating immune complexes (CIC). Fewer than 10% of the men examined were ever positive for antisperm antibodies. However, sperm-related antigens were elevate
