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 related to particularities of each disease. This re...

The association of antisperm antibodies and autoimmunity or presence of gamma delta T cells in semen associated with men with ASA related infertility has been recognized as early as the early 90’s with specific correlation with antiphospholipid antibodies but it has been concluded in a review in 2002 by Mclachlan RI 2002 that since IUI/ICSI is the final answer there is no point in bothering abo...

OBJECTIVE To examine effects of nondescent of normal testis and of various orchidopexy techniques on antisperm antibody (ASA) production and histologic testicular lesions. DESIGN Experimental cohort study. SETTING Laboratories of surgical research and biology of reproduction, academic medical centers. PATIENT(S) Lewis rats, immature and adult. INTERVENTION(S) Eighteen-day-old rats (6 gr...

Male factors account for 20%-50% of cases of infertility and in 25% of cases, the etiology of male infertility is unknown. Effective treatments are well-established for hypogonadotropic hypogonadism, male accessory gland infection, retrograde ejaculation, and positive antisperm antibody. However, the appropriate treatment for idiopathic male infertility is unclear. Empirical medical treatment (...

Some previous studies have identified bacteria in semen as being a potential factor in male infertility. However, only few types of bacteria were taken into consideration while using PCR-based or culturing methods. Here we present an analysis approach using next-generation sequencing technology and bioinformatics analysis to investigate the associations between bacterial communities and semen q...

The present study was taken to characterize molecular weights of sperm specific polypeptides antigenic to rabbits and calf with the aim to assess their immunoreactivity with IgG antibodies in sera from immuno-infertile cows. Seropositivity for antisperm IgG antibodies in 75 repeat breeder and 15 pregnant control cattle was tested by cellular ELISA using washed spermatozoa antigen from 4 bulls. ...

According to the microcosmic Syndrome Differentiation, immunological infertility is recognised as Kidney Yin Deficiency-Hyperactivity of Fire Syndrome. Zhibai Dihuang Pills, a recipe of Chinese medicinal herbs, was used to treat the infertile couples with antisperm and/or antizona pellucida antibodies in their blood serum. It was found that after the treatment, the antibodies were converted to ...

Clinically, antibodies against sperm are found in 3% to 12% of men who undergo evaluation for infertility and can be found in the serum, seminal plasma or sperm-bound. As antibodies in the serum cannot logistically bind to sperm unless they transudate into semen, these immunoglobulins are considered clinically less important than sperm-bound antibodies. The presence of anti-sperm antibodies in ...

BACKGROUND The aim of this study was to investigate the effects of sleep duration and bedtime on sperm health, and the possible mechanism involved. MATERIAL AND METHODS We randomly divided 981 healthy Chinese men into groups according to research-set bedtimes (A=8-10 PM, B=after 10 PM, and C=after midnight) and sleep durations: group 1=<6.0 h (short), group 2=7.0-8.0 h (average), and group 3=>9...
