Semen predictors of in vitro fertilization and embryo cleavage

Article Abstract:

In vitro fertilization is the process by which a female egg is fertilized by male sperm, outside the body, to produce an embryo that is then placed inside the uterus. Although this process is used primarily in cases of female infertility, male infertility can also benefit from this process. The characteristics of sperm will determine the success of in vitro fertilization for couples thinking about in vitro fertilization because of male infertility. The quality of sperm of 76 patients were analyzed to determine the best variable for a successful embryo cleavage which indicates a viable embryo. The results of the swim-up method of sperm analysis revealed that at least 10 million sperm per milliliter, capable of swelling in a low salt solution (hypoosmotic swelling test) is needed for successful in vitro fertilization. It is suggested that this test, which is easy to perform, be a preliminary screening test in patients considering this method of fertilization.

A simplified method of timing frozen embryo transfers

Article Abstract:

The timing of when to transfer frozen embryos into a woman's uterus in conjunction with in vitro fertilization may be simplified by artificially controlling the menstrual cycle with hormone replacements without depressing the function of the pituitary gland. Embryos should be transferred at a certain time in the menstrual cycle to increase chances of implantation and successful pregnancy. Researchers compared the use of three hormone replacement treatments, one of which did not include reduction of pituitary function, in the transfer of 366 frozen embryos. All three achieved comparable pregnancy rates, suggesting that reduction of pituitary function is not necessary in promoting pregnancy. The hormone used to reduce pituitary function is expensive.
