Yasemin Yilmazer et al.
Infertility affects 15% of all couples worldwide and 50% of cases of infertility are solely due to male factors. A decrease in motility in the semen is considered one of the main factors that is directly related to infertility. The use of s...
Has the concept of polyspermy prevention been invented in the laboratory? [0.03%]
多精子阻止的概念是否是在实验室里发明的？

There is no evidence, nor need, for a fast block to polyspermy in animal oocytes. The idea that oocytes have evolved a mechanism to allow the entry of one spermatozoon and repel all others has, however, gained consensus over the last centur...
Protective efficacy of Nerium oleander extract on spermatogenesis in streptozotocin-induced diabetic rats [0.03%]
夹竹桃提取物对链脲佐菌素诱导糖尿病大鼠精子发生的影响研究
Afrooz Karimi,Farhad Kohpeyma,Ebrahim Asadi et al.
Afrooz Karimi et al.
Men with diabetes frequently experience spermatogenic dysfunction, which is the most significant sign that diabetes has harmed their ability to reproduce. The effect of various doses of the hydro-alcoholic extract of Nerium oleander leaves ...
The identification and classification of candidate genes during the zygotic genome activation in the mammals [0.03%]
哺乳动物合子基因组激活过程中的候选基因的识别与分类
Kaiyue Hu,Wenbo Li,Shuxia Ma et al.
Kaiyue Hu et al.
Zygotic genome activation (ZGA) is a critical event in early embryonic development, and thousands of genes are involved in this delicate and sophisticated biological process. To date, however, only a handful of these genes have revealed the...
Rreb1 is a key transcription factor in Sertoli cell maturation and function and spermatogenesis in mouse [0.03%]
Rreb1是小鼠支持细胞成熟和功能以及精子发生的的关键转录因子
Zhu Wu,Xu Chen,Tong Yan et al.
Zhu Wu et al.
Spermatogenesis is a developmental process driven by interactions between germ cells and Sertoli cells. This process depends on appropriate gene expression, which might be regulated by transcription factors. This study focused on Rreb1, a z...
Comparative study of intracytoplasmic sperm injection using the traditional holding and the oocyte-holding pipette without aspiration [0.03%]
传统吸持法和非吸入卵母细胞吸管的胞浆内精子注射法的对比研究
Francisco Vergara,Javier Fernández,Concepción Pedrosa et al.
Francisco Vergara et al.
Despite the high level of standardization of the intracytoplasmic sperm injection (ICSI) technique, there are some aspects that deserve special attention and should still be improved. The major drawback of the technique is its invasiveness,...
Ultrastructural study: in vitro and in vivo differentiation of mice spermatogonial stem cells [0.03%]
小鼠精原干细胞体内外分化的超微结构研究
Zahra Bashiri,Mansoureh Movahedin,Vahid Pirhajati et al.
Zahra Bashiri et al.
Mouse testicular tissue is composed of seminiferous tubules and interstitial tissue. Mammalian spermatogenesis is divided into three stages: spermatocytogenesis (mitotic divisions) in which spermatogonial stem cells (SSCs) turn into spermat...
Structural and metabolic cumulus cell alteration affects oocyte quality in underweight women [0.03%]
