spermatogenesis造句
31, CONCLUSION:Disturbance of spermatogenesis and damage of sertoli cell are the main morphological change of diabetic testis, lipid peroxidation and NO may be involved in it.
32, The expression of genes are subject to meiotic sex-chromosome inactivation(MSCI) during spermatogenesis, but lots of gene transcripts are reactivated in postmeiotic.
33, Objective:To estimate the number of spermatids generated by one primary spermatocyte and thus evaluate the efficiency of meiosis during spermatogenesis in normal adult men.
34, To investigate the relationship between spermatogenesis disorder and genetic defects of patients with azoospermia or severe oligospermia.
35, However, in cryptorchid testis, in which most germ cells undergo apoptosis, only a few of SRG4 is observed, suggesting that SRG4 may be as a specific marker to evaluate the process of spermatogenesis.
36, The effects of artificial cryptorchism on spermatogenesis in rats were analysed by using HE staining and in situ DNA 3, -end labeling technology.
37, The expression of sperm-specific genes is necessary in spermiogenesis , and the genetic polymorphism of these genes may impair spermatogenesis, leading to male infertility.
38, In the spermatogenesis, Sertoli cell showed the typical ultrastructure features of steroid hormone secreting cell.
39, During spermatogenesis two pairs of basal body-axoneme complexes originated from centrioles are found in the spermatocyte and they are separated completely from each other at interkinesis.
40, Objective:To further explore the regulatory role of the spermatic nerves in spermatogenesis by investigating effects of testicular denervation on sexual hormone levels.
41, However, focal spermatogenesis and severe oligozoospermia have been found in a few cases of 47, XXY, too.
