Evaluation of the effects of feeding male mice with palm, fish and sunflower oil on sperm characteristics and sex ratio of offspring

Beheshteh Abouhamzeh; Reza Youssefi; Vahid Akbarinejad; Ehsan Mirsadeghi

Volume 11, Issue 4 , December 2020, , Pages 319-323

  Several studies have indicated that feeding female animal with fatty acids could result in alteration of offspring sex ratio; however, there is little information available regarding the effect of feeding male animal with fatty acids on sex ratio of offspring. The aim of current study was to investigate ...  Read More

Effect of extracellular matrix on testosterone production during in vitro culture of bovine testicular cells

Vahid Akbarinejad; Parviz Tajik; Mansoureh Movahedin; Reza Youssefi

Volume 8, Issue 1 , March 2017, , Pages 7-13

  Testosterone is believed to play a significant role in spermatogenesis, but its contribution to the process of spermatogenesis is not completely understood. Given that extracellular matrix (ECM) facilitates differentiation of spermatogonial stem cells (SSCs) during culture, the present study was conducted ...  Read More

Enhancement in colonization of bovine spermatogonial stem cells following addition of knock-out serum replacement to culture medium

Reza Youssefi; Parviz Tajik; Mansoureh Movahedin; Vahid Akbarinejad

Volume 7, Issue 4 , December 2016, , Pages 275-280

  Enrichment of cell suspension with germ cells prior to injection into recipient seminiferous tubules is of importance in spermatogonial stem cells (SSCs) transplantation. Knock-out serum replacement (KSR) has been reported to enhance the proliferation of murine SSCs and human embryonic stem cells. The ...  Read More

Effects of diets supplemented by fish oil on sex ratio of pups in bitch

Faramarz Gharagozlou; Reza Youssefi; Vahid Akbarinejad

Volume 7, Issue 2 , June 2016, , Pages 105-110

  The present study was conducted to evaluate the effect of fish oil supplementation prior to mating on secondary sex ratio of pups (the proportion of males at birth) in bitches. Sixty five bitches (German Shepherd, n = 35; Husky, n = 30) were enrolled in the study. Bitches (140-150 days post-estrus) were ...  Read More

Stem Cells
The role of fibroblast growth factor receptor 2 (FGFR2) in differentiation of bovine spermatogonial stem cells (SSCs)

Vahid Akbarinejad; Parviz Tajik; Mansoureh Movahedin; Reza Youssefi

Volume 7, Issue 2 , June 2016, , Pages 149-153

  The receptors 1 and 2 of fibroblast growth factor (FGFR1 and FGFR2, respectively) have been observed in all types of testicular cells. Culture on extracellular matrix (ECM) has been observed to lead to initiation of differentiation in spermatogonial stem cells (SSCs). The present study was carried out ...  Read More

Androgen receptor blockade using flutamide skewed sex ratio of litters in mice

Faramarz Gharagozlou; Reza Youssefi; Mehdi Vojgani; Vahid Akbarinejad; Ghazaleh Rafiee

Volume 7, Issue 2 , June 2016, , Pages 169-172

  Maternal testosterone has been indicated to affect sex ratio of offspring. The present study was conducted to elucidate the role of androgen receptor in this regard by blockade of androgen receptor using flutamide in female mice. Mice were randomly assigned to two experimental groups. Mice in the control ...  Read More
