BACKGROUND Thioglycolic acid (TGA) is widely used in the hairdressing industry, which mostly caters to women. Recently, TGA has been reported to impair several organs, especially reproductive ones such as testes and ovaries. The reproductive toxicity of TGA on females has become an issue that cannot be neglected. METHODOLOGY/PRINCIPAL FINDINGS In the present work, superovulated female mice we...

ABSTRACT The objective of this study was to quantify the superovulatory response and embryo production Brazilian Bergamasca sheep evaluate link follicular condition before treatment, as a reference for selection donors with potential superovulation. Follicular population twenty-three evaluated by ultrasound during metestrus phase estrous cycle divided into groups low, medium high population. Su...

The success rates of assisted reproduction techniques are still unsatisfactory. Relatively few in vitro cultured embryos reach the blastocyst stage. The purpose of the study was to evaluate the protective potential of epidermal growth factor (EGF), insulin-like growth factors 1 and 2 (IGF-I, IGF-II) and stem cell factor (SCF) on in vitro development of pre-implantation mouse embryos exposed to ...

Mouse oocytes can be obtained via superovulation or using in vitro maturation although several factors, including genetic background, may affect response. Our previous studies have identified various mouse species as models to understand the role of sexual selection on the evolution of sperm traits and function. In order to do comparative studies of sperm-oocyte interaction, we sought reliable ...

The aim of this study was to examine the effect of thyroxine on ovulation in immature rdw rats and the fertilization and development of the eggs. Serum thyroxine concentrations at 30 days of age were significantly lower in rdw rats than in normal rats (P < 0.001), and greatly increased after thyroxine replacement therapy (P < 0.001). Although few eggs (1-5 +/- 1-2) were obtained from immature r...

Philemon buceroides is a bird that very difficult to breed in captivity. This paper escribes the breeding efforts have been carried out. The aims of study are for knowing how it captivity and as suggestion conservation in-situ ex-situ. Efforts conducted by supplying Pregnant Mare Serum Godadotrophin (PMSG) hormone Estrogen artificial insemination birds sexually mature at least one year old phys...

On a worldwide basis, more than 750,000 embryos are produced annually from superovulated donors and more than 450,000 embryos are produced using in vitro techniques. Superovulation and embryo collection are done as frequently as every 30 days. Cryopreservation and direct transfer of frozen-thawed embryos results in pregnancy rates near that of fresh embryos. Since the zona pellucida-intact in v...

Artificial insemination (AI) subfertility is an indication of failure of AI with frozen-thawed sperm classified as normal by conventional semen examination. Recently, 8 AI-subfertile Japanese Black cattle (S1-S8) were identified using the routine AI test or in vivo fertilization test, which included AI with frozen-thawed sperm of superovulated females and subsequent non-surgical recovery of pre...

Poverty, a complex, multidimensional, and universal problem, has been conceptualized as income and material deprivation. In this article, we discuss poverty and related factors in Turkey. The absolute poverty line for Turkey was US$ 4 per capita per day. Turkey was ranked 92nd out of 177 countries with moderate human development in the 2006 Human Development Report. The individual food poverty ...
