background: recurrent abortion is defined as three or more consecutive pregnancy losses. we aimed to determine the relationship between male sperm parameters and hypo-osmotic swelling score and recurrent abortion. we also studied whether washing of spermatozoa and intrauterine insemination in patients with recurrent miscarriage and low score hypo-osmotic swelling test in male partners could imp...

background: recurrent abortion is a difficult medical problem happening in about 1-2% of fertile women. most spontaneous miscarriages which happen in the first and second trimesters are caused by chromosomal abnormalities. objective: the present study tries to find the rate of chromosomal abnormalities in couples with recurrent pregnancy loss. materials and methods: in total 165 couples were re...

Background & Aims: It is believed that uterine septum, because of its effect on infertility and recurrent abortion is very important and pregnancy outcome is obviously improved by hysteroscopic metroplasty (HM). In this study, the probable relationship of uterine septum dimensions (length and width) with infertility and recurrent abortion has been investigated. Methods: This clinical trial was ...

background: recurrent spontaneous abortion impacts almost 1% of couples. the sera from women with unexplained recurrent spontaneous abortion (ursa) have toxic effects on embryos that grow in the uterus. therefore, the abnormal condition of the uterus may also affect sperm qualities. objective: the objectives of this study were to search if these sera could induce dna denaturation in sperm nucle...

objective: this study determined the chromosomal constitution of recurrent spontaneous abortions by comparative genomic hybridization (cgh) analysis of fetal samples. material and methods:   forty pregnant women with early recurrent pregnancy losses aged 21 to 42 years old from tehran university of medical sciences affiliated hospitals entered in this descriptive study. hibridization analysis o...

the measurment of various cytokines may provide a different tool for evaluation of the immune system. recent investigations have shown that the number and function of peripheral natural killer cells (nk- cells) increase during early pregnancy in women with a history of unexplained recurrent spontaneous abortions (rsa). nk-cells activity may be responsible for some cases of rsa. the objective of...

background: miscarriage is one of the most common pregnancy complications for which various causes have been defined, such as genetic factors, infectious, metabolic, endocrine systemmal function and immune system undesired responses. the early development of embryo occurs in oviduct and uterine tube from which some factors such as growth factors, glyco-proteins and factors those stimulate devel...
