Example sentences for: spermatogenesis

How can you use “spermatogenesis” in a sentence? Here are some example sentences to help you improve your vocabulary:

  • Indeed, p53 controls the low-level damage-dependent premeiotic checkpoint which facilitates DNA repair during spermatogenesis [ 25 ] . Gametogenesis is inherently error-prone [ 26 ] and subject to mutations [ 27 ] . Nevertheless, it is imperative to avoid genotoxic complications that could become integrated into the germline.

  • The adult testis is a complex organ consisting of numerous different somatic cell types as well as germ cells at all stages of spermatogenesis from the gonocyte stem cells to the mature sperm cells [ 18 ] . Consequently, several unique gene populations, including those involved in the regulation of meiosis, as well as those specific to the various testicular cell types, are expressed in the testis.

  • , [ 10 12 13 14 15 ] ]. It is thought to regulate spermatogenesis and sperm maturation by maintaining high androgen levels in the testis and epididymis [ 16 17 ] and has been proposed as a biochemical marker for Sertoli cell function and formation of blood-testis barrier [ 12 18 ] . More recently, cell surface receptors for ABP and its liver-derived homolog sex hormone-binding globulin (SHBG) were identified in several androgen target tissues, suggesting that these extracellular steroid-binding proteins may have a much broader, hormone-like function [ 19 20 21 ] .

  • [19] cloned fog-2 , a gene required for spermatogenesis in hermaphrodites but not in males.

  • Normal spermatogenesis represents a precisely regulated balance between continuous cell proliferation and concomitant programmed cell death, apoptosis [ 1 2 3 4 ] . More than 50% of the germ cells die during their normal developmental process [ 5 6 ] . Apoptosis in the testis of rodents is detected as early as the 14 thembryonic day [ 7 ] . After birth, an early apoptotic wave of germ cells during a critical pre-pubertal period (around 3-4 weeks) [ 8 ] may be required for determining the subsequent normal pattern of spermatogenesis [ 3 ] .
