in this study, chromosome analyses were performed on 70 infertile azoospermic and oligospermic (<20 million/ml) men, and also cultures of peripheral blood lymphocytes by high resolution banding method were analysed as well. it is revealed 8 (11.43 percent) men with chromosomal abnormality. there were 31.4 percent patients with azoospermia and 68.6 percent with oligospermia from several thousand...

The most common cause of pregnancy losses is chromosomal anomalies. Fetal chromosomal anomalies are found in 90% preembryonic losses, 50% first trimester abortions, 2/3 malformed embryos, and 1/3 malformed fetuses. Considering all pregnancy losses, the rate 50%...

early identification of fetuses with chromosomal abnormalities enables health care providers to form an appropriate management plan for each patient. the main objective of this study was to determine the role of ultrasonography in screening and identifying fetuses at risk for chromosomal abnormalities. a retrospective review of 6480 patients from the obstetrics and gynecology ward of firouzgar ...

BACKGROUND The presence of a congenital anomaly is associated with increased childhood cancer risk, likely due to large effects of Down syndrome and chromosomal anomalies for leukemia. Less is known about associations with presence of non-chromosomal anomalies. METHODS Records of children diagnosed with cancer at <20 years of age during 1984-2013 in Washington State cancer registries were lin...

Background & Aims: Chromosome abnormalities are a major cause of miscarriage and neonatal mortality. The present study aimed to determine the association of fetal and parents chromosomal abnormalities with congenital anomalies. Methods: A cross-sectional study was performed in a tertiary referral center (Afzalipour Hospital) over 16 months period (2011-2012). The study groups consisted of 77 fe...
