The advent of technologies to genetically manipulate the mouse genome has revolutionised research approaches, providing a unique platform to study the causality of reproductive disorders in vivo. With the relative ease of generating genetically modified (GM) mouse models, the last two decades have yielded multiple loss-of-function and gain-of-function mutation mouse models to explore the role o...
Sir, We have read the article published in your journal by Taylor et al. (2014) with much interest. In this review the authors properly summarize the mechanisms, origins and incidence of chromosomal mosaicism in humans. The review is rigorous, exhaustive and very well-documented, and therefore we congratulate the authors for their work. Nevertheless, we find that some relevant information about...
In order to assess the role of the gonads and anterior pituitary gland in the production of poor quality semen of males with homozygous sickle cell disease (SCD) serum gonadotrophins, namely follicle stimulating hormone (FSH), luteinizing hormone (LH), prolactin and serum testosterone, were assayed radioimmunologically in 33 men with sickle cell disease and in 29 age-matched normal control subj...
Four boys with Fanconi's anaemia and growth hormone (GH) deficiency are reported. Case 1 had isolated GH deficiency and responded to HGH and to oxandrolone treatment. Case 2, his brother, had milder haematological and dysmorphic manifestations and maintained a low-normal growth rate without treatment in spite of laboratory evidence of GH deficiency. Case 3 had multiple hypothalamopituitary defe...
Changes in vaginal epithelium are known to occur during the normal oestrous or menstrual cycle and in ovariectomised animals in response to various hormones. However, vaginal changes due to exogenous gonadotrophins superimposed on the normal hormonal milieu as occurs in in vitro fertilisation programmes have not previously been demonstrated. Female rats were hyperstimulated with follicle stimul...
