Abstract

Neem oil is a natural product from the seed-kamel of the "wonder tree" Azadirachta indica. In addition to its various applications in the treatment of different ailments, it also possesses spermicidal and post-coital antifertility properties. Therefore, a study was undertaken with a purpose to know its contraceptive effect on the biochemical composition of uterine fluid, which is a composite of secretions from the endometerial gland and serum transudates, which is responsible for making internal biochemical melieu of uterus suitable for sperm Capaciation, fertilization, implantation and as a histotroph for developing blastocyst, uterine contractibility and fertility.

Abstract

Natural selection has provided the mammal with a rich variety of signaling systems, each of which couples environmental variation with appropriate neuroendocrine responses. Therefore the complicated processed of mammalian reproduction occurs in harmony with exhisting dietary factors and different aspects of physical environmental. In recent years the study of low nutrients and their metabolism as well as various environmental factors effect reproductive processes has gained a great momentum., several research articles reveal that environmental factors and nutritional status directly or indirectly modulate reproduction in mammals. In general the male reproductive system show much more resistance to malnutrition and photoperiodic length of environmental factors alone influences the seasonal changes in testicular volume in sheep as earlier reported by Martin (1984).

Abstract

Human Seminal plasma is the nongemetic portion of an ejaculate at the time of insemination which acts as a fluid for the transport of male gamates in the female reproductive tract by acting as a buffered medium. It contains nutrients for spermatozoa in a species specific volume and density. Seminal quality is a classic index for male fertility. Earlier reports indicates that antibodies of the ABO-system of blood group affect the human spermatozoal metabolism.
