BACKGROUND Tubal factor infertility is one of the main causes of female infertility. Although its sensitivity is low, hysterosalpingography (HSG) is remains the first-line method for evaluating tubal patency. AIMS To compare pregnancy rates in patients with HSG proven proximal or distal unilateral tubal occlusion, and unexplained infertility undergoing both controlled ovarian stimulation (COS...

BACKGROUND Intrauterine insemination (IUI) is one of the therapeutic approaches for infertility. The objective of this study was to evaluate DNA integrity and apoptosis role in success of IUI in both mild male and female factor infertility. METHODS PATIENTS WERE DIVIDED INTO TWO GROUPS: M (mild male factor; n = 29) and F (female factor; n = 31) undergoing single IUI. Ejaculates were analyzed ...

BACKGROUND The success of intrauterine insemination with donor semen (IUI-DI) is likely to be influenced by a number of variables, including age and ovarian stimulation (OS) regime. METHODS AND RESULTS A retrospective analysis of 1056 treatment cycles in 261 women (212 single heterosexuals and 49 lesbians) was conducted to assess the influence of these two variables on pregnancy outcome durin...

The use of ovulation induction combined with intrauterine insemination (IUI) as a treatment for subfertility in women with patent Fallopian tubes has increased in recent years. Little is known regarding the efficacy of this treatment in women aged >/=40 years. We reviewed our data in our ovulation induction with IUI programme for 168 consecutive patients aged >/=40 years undergoing a total of 4...

Introduction Recently, a new procedure for intrauterine insemination (IUI) in sows has been established (1,2). The procedure consists of a specially designed catheter that can be passed through the cervix allowing the deposition of sperm in the uterus. Using this technique, the number of spermatozoa per dose can be reduced by up to 1 billion spermatozoa. It has been demonstrated that the IUI te...

INTRODUCTION Male infertility factor is defined if the total number of motile spermatozoa (TMSC) < 20 × 10(6)/ejaculated, and unexplained infertility if spermiogram is normal with normal female factor. THE AIM of this study was to determine the predictive value of TMSC for spontaneous pregnancy (ST) and pregnancy after treatment with intrauterine insemination (IUI) in couples with male factor...

Background: Intrauterine insemination with ovarian stimulation (IUI-OS) is a first-line treatment for couples unexplained infertility. Individual participant data meta-analysis (IPD-MA) the gold standard evidence synthesis. Aim: To compare effectiveness and safety of gonadotrophin, Letrozole clomiphene citrate (CC) to explore treatment-covariate interactions important baseline characteristics i...
