Journal of assisted reproduction and genetics, 2012•SpringerPurpose The purpose of the present study was to investigate the impact of
lipopolysaccharide (LPS) on follicle-stimulating hormone (FSH), luteinizing hormone (LH)
and their receptors during preimplantation days of pregnancy. Method The PBS or
lipopolysaccharide (LPS) was injected intraperitoneally in the pregnant females on day 0.5
of pregnancy and serum, embryos, ovaries and uterine horns were collected on days 1.5,
2.5, 3.5, 4.0, 4.125, 4.33 and 4.42 of pregnancy. Result (s) In the LPS-treated pregnant …

Purpose
The purpose of the present study was to investigate the impact of lipopolysaccharide (LPS) on follicle-stimulating hormone (FSH), luteinizing hormone (LH) and their receptors during preimplantation days of pregnancy.
Method
The PBS or lipopolysaccharide (LPS) was injected intraperitoneally in the pregnant females on day 0.5 of pregnancy and serum, embryos, ovaries and uterine horns were collected on days 1.5, 2.5, 3.5, 4.0, 4.125, 4.33 and 4.42 of pregnancy.
Result(s)
In the LPS-treated pregnant females, the secretion of FSH and LH is disturbed with respect to normal pregnancy. Furthermore, the expression of FSHR mRNA in embryos and ovaries, LHR mRNA in embryos and uterus get modulated in response to LPS during preimplantation days of pregnancy.
Conclusion(s)
The disturbance in the serum level of FSH and LH in response to LPS leads implantation failure in mouse which suggests that these gonadotropins plays an integral role in the process of the successful implantation. This study also suggests a possible nongonadal role of FSHR and LHR in LPS-induced implantation failure in the mouse.
