CHEHREIE, Shima; RABZIA, Arezou  y  FARHADI-MESTERKHANI, Mohammad. Maternal Water Deprivation Affects the Spermatogenesis of the Offspring Rats. Int. J. Morphol. [online]. 2013, vol.31, n.1, pp.156-161. ISSN 0717-9502.

Prenatal stresses such as water deprivation affect developmental process of embryo. This study evaluated the effects of water deprivation in pregnant mother on histological parameters of testis of offspring. Pregnant rats were divided into two groups (control and experimental). In experimental animals, water was removed from the ewes for 48h at the end of third trimester of gestation (19-21th days). Histopathology and histomorphic analysis and also TUNEL assay on offspring's testes were performed at pubertal age (60 days). The sperm motility either compared between two groups. The results showed that prenatal water deprivation induced histopathological alteration such as epithelium vacuolization, sloughing and detachments (P<0.01). Morphometrical data showed that prenatal water deprivation decreased tubular diameter and reduce epithelium height (P<0.01). Johnsen's score showed poor spermatogenesis in experimental group (P=0.001). The percent of germ cell apoptosis was increased in offspring's testes of rats born to mothers exposed to stress during pregnancy (P=0.000). The increased number of Multinucleated cells in the seminiferous lumen (P=0.000) in parallel with decreased number of sertoli cells (P=0.03) showed adverse effect of prenatal water deprivation on blood testis barrier. Present study revealed that prenatal water deprivation had injurious effect on developmental process of testes that affects on both germ cells and sertoli cells and had noxious effect on sperm parameters. These data confirm that prenatal stress disrupts normal spermatogenesis of offspring.
