Deep learning enables robust assessment and selection of human blastocysts after in vitro fertilization

npj Digital Medicine, 2019
Visual morphology assessment is routinely used for evaluating of embryo quality and selecting human blastocysts for transfer after in vitro fertilization (IVF). However, the assessment produces different results between embryologists and as a result, the

Expression and potential roles of HLA-G in human spermatogenesis and early embryonic development. [PDF]

PLoS ONE, 2014
As one of the non-classical major histocompatibility complex(MHC)-1 antigens, Human Leukocyte Antigen G (HLA-G), has been suggested as a prognostic marker to identify the embryo developmental potential. In the present study, we investigated the potential

THE INFLUENCE OF RADIATION ON HUMAN FERTILITY [PDF]

Reproduction, 1968
The number of children born to 180 females exposed to abdominal fluoroscopy in connection with an attack of intussusception in infancy or childhood was compared to the number born to women who were treated for the same disease without fluoroscopy. No difference was found between the number of children born or the age distribution of birth between the ...

Effect of Lepidium meyenii on in vitro fertilization via improvement in acrosome reaction and motility of mouse and human sperm

Reproductive Medicine and Biology, 2019
Purpose The direct effects of Lepidium meyenii (Maca) on sperm remain unclear. Herein, we examined the direct effect of Maca on in vitro fertilization. Methods We examined the fertilization rate in a mouse model and the rate of acrosome reaction in sperm

#35 : Tail-First Sperm Injection Significantly Improved the Fertilization Rates More Than the Head-First Sperm Injection Regardless of the Elasticity of the Oocyte Membrane Following Piezo-ICSI

Fertility & Reproduction, 2023
Background and Aims: Little information is available for investigating the effect of the direction of sperm injected into the cytoplasm on clinical results for human oocytes following intracytoplasmic sperm injection (ICSI).

Smoking, haptoglobin and fertility in humans

Tobacco Induced Diseases, 2003
A prospective study on two samples of consecutive puerperae (total n degrees 667) from two populations has been carried out in order to investigate the possible effect of smoking habit on relationship between fertility and haptoglobin phenotype.In both populations the negative association previously reported between age of pueperae and Haptoglobin *1 ...

Rapid response of arbuscular mycorrhizal fungal communities to short-term fertilization in an alpine grassland on the Qinghai-Tibet Plateau [PDF]

PeerJ, 2016
Background: The Qinghai-Tibet Plateau (QTP) is home to the vast grassland in China. The QTP grassland ecosystem has been seriously degraded by human land use practices and climate change. Fertilization is used in this region to increase vegetation yields
