Introduction:

The "mashua", Tropaeolum tuberosum, is a plant species native to Peru. Research carried out has proven its effects on the fertility of mammals.

Objective:

To evaluate the biological action of the aqueous solution of T. tuberosum in the development of preimplantation embryos of Mus musculus and the reproductive capacity of male Mus musculus.

Methods:

Preclinical experimental study of cases and controls. The sample consisted of 32 mice, the case group was made up of 24 mice grouped into three groups, each one of 8 mice, to whom aqueous extract was administered ad libitum, at a concentration of 50 g / Kg of body weight for 8, 16 and 35 days respectively, the control group consisted of 8 mice, who received only tap water. Each group of males were crossed with females of fertile age, the presence of a vaginal plug indicated day 0 of embryonic development. At 72 h the uterine horns and oviducts were perfused and the degree of development, condition and preimplantation embryonic morphology of Mus musculus were evaluated until reaching the blastocyst stage.

Results:

Statistically significant differences were found between the case and control groups. Our results show that the administration of aqueous solution of T. tuberosum to male mice alters the reproductive quality of the mouse, affecting the ability of the embryo to develop normally until the blastocyst stage.

Conclusion:

The aqueous extract of Tropaeolum tuberosum (mashua) affects preimplantation embryonic development and reproductive capacity in male Mus musculus
