R-164. Assisted fertilization in cases of chromosomal abnormality

Cytogenetic Analysis of Referral Cases with Growth Failure and Clinical Suspicion of having Chromosomal Abnormality

  Background and Objective: Failure to thrive (FTT) is a sign that describes a particular problem rather than a diagnosis and explain growth failure or more advanced failure to gain weight appropriately. The aim of this study was to determine the prevalence and type of chromosomal abnormalities in patients presented with FTT. Materials and Method: One hundred FTT cases with clinical impressio...

Chromosomal Abnormality in Men with Impaired Spermatogenesis

Chromosomal Abnormality in 500 Referred Cases in Bahrain

Main Outcome: 134 (27 %) patients had abnormal karyotype, 97 (19 %) patients had numerical abnormalities and 37 (7 %) had structural chromosomal abnormalities. The majority of patients with numerical abnormalities (66 %) were Down Syndrome or trisomy 21, 4 % were having trisomy 13, and 4 % were having trisomy 18. Cases of X chromosome abnormalities were found in 13 % of the abnormal causes, whi...

the chromosomal abnormality of failed fertilized human oocytes in an in vitro fertilization program

background: the high fertilization failure after ivf treatment cycles could be related to chromosomal abnormalities. this study was carried out to assess the frequency of chromosomal abnormality on human oocytes lacking signs of fertilization 18-20 h after insemination . materials and methods: on day one, 18-20 h after insemination (ivf), fertilization was confirmed when two pronuclei (normal i...

Consanguinity and chromosomal abnormality

BACKGROUND: Consanguinity is defined as the marriage between close relatives. The deleterious effects associated with consanguinity may be caused by the expression of rare recessive genes inherited from common ancestors. AIMS AND OBJECTIVES: The present study was undertaken to analyze the effect of consanguinity on chromosomal abnormality (CA). METHODS AND MATERIALS: During last 6 years period,...
