Naturally-occurring anti-sperm antibodies (ASA) in men can affect fertility by various mechanisms. Some of them are mainly related to the extent of the sperm autoimmunization (e.g., sperm-agglutination and impaired cervical mucus penetration); others are also related to immunoglobulin (Ig)-isotype (e.g., complement-mediated sperm injury through the female genital tract), or to antigenic specifi...

Using a prospective design over three complete menstrual cycles, 147 heterosexual and 89 lesbian women made daily recordings of their basal body temperature (BBT), cervical mucus status, menses, and completed a daily checklist of various sexual behaviors (including sexual self-stimulation and sexual activity with a partner). They also gave their age, height, weight, age at menarche, number of p...

PURPOSE To evaluate the effects of oral contraceptives (OCs) on uterine contractility using cine MRI, and correlate the kinematic findings with the static findings. MATERIALS AND METHODS Healthy female volunteers of reproductive age (23 taking OCs, and 15 not) were evaluated at mid-cycle. MR images were obtained with a 1.5T magnet, with 60 serial images taken every three seconds by half-Fouri...

Present study was designed to assess the effect of catalase on post-thaw semen quality parameters (SQPs), sperm kinematics, antioxidant and oxidative stress profiles cholesterol efflux in mithun (Bos frontalis). A total 25 ejaculates were selected based biophysical each sample split into four equal aliquots diluted (to get final concentration 60 million spermatozoa per mL) with TCG extender con...

The concentrations of immunoglobulin A (IgA) and immunoglobulin G (IgG) were estimated in cervical mucus from 115 patients attending a clinic for sexually transmitted diseases. The patients were divided into two groups; those using combined estrogen/progestogen oral contraceptives, and those with presumed normal ovulatory cycles. Gonorrhea, trichomoniasis, candidosis, and herpes genitalis were ...

The outcome of Kremer testing has been evaluated daily, during the mid-cycle, in 15 healthy women over three menstrual cycles, using a permanent and a variable normal, male donor. There was a significant correlation (r = 0.539; t = 6.33; P less than 0.001, n = 100; Spearman rank correlation with correction for ties) between the results obtained with the two men. The best Kremer test results wer...

Examination of immunity disorders at the system and local levels in pregnant women with persistent mycoplasma infection has been carried out. The analysis has revealed depression of circulating in blood CD3+ and CD4+, increase of CD16+ and CD19+, decrease of activated CD25+ and ready to adaptation CD95+ lymphocytes. Studies of the concentration of cytokines at the local level (cervical mucus) i...
