Semen analysis is an integral part of the workup of couples consulting for infertility. The availability of semen renders possible direct examination of male germ cells, giving precious data that are not accessible for female germ cells. Altogether these data give indications on the testicular function and of the integrity of the male genital tract. Normal values of semen parameters have been issued by WHO in that are generally used as reference.
The Fertility Institutes offers the highest standard of reproductive medicine. Egg freezing can free you from the biological clock to extend your age of fertility. Our clinics offer leading IVF Programs with expert fertility evaluation and answers. Advanced PGD genetic screening of embryos for over hereditary diseases. One of the biggest concerns of couples involved in an infertility work up relates to the status of the male partner's sperm evaluation. While the thorough evaluation of sperm and sperm function should be given high priority in any infertility evaluation, we have found from our web page interactions with patients that often times the couple are told very little related to test results in this area. Or, in other cases, we hear of couples being told about "high numbers" of "abnormal" sperm, or "low" numbers of "good" sperm with little additional information about what those results mean to their chances for conception.
Cadmium is a major environmental toxicant that is released into the atmosphere, water and soil in the form of cadmium oxide, cadmium chloride, or cadmium sulfide via industrial activities, such as the manufacturing of batteries and pigments, metal smelting and refining and municipal waste incineration. In the present study, we investigated the effects of cadmium exposure on sperm quality parameters, fertilization capacity and early embryonic development. Our study showed that in vitro incubation of human or mouse sperms with cadmium for a long time up to 24 hours could significantly decreased sperm motility in a concentration- and time-dependent manner. Exposure to cadmium in the environment for a short term 30 min did not affect sperm motility but significantly reduced in vitro fertilization rate. We also evaluated the effects of cadmium at concentrations of 0.
