However, whilst there may, of course, be medical reasons for not getting pregnant that could be affecting your ability to conceive, it is important not to worry about this prematurely. The amount of time it can take for couples to conceive can vary significantly. If you have only been trying for six months to a year and if there are no known contributory factors, then generally there should be no cause for concern. If you do discover that there are medical reasons for not getting pregnant, such as conditions including amenorrhea , PCOS , endometriosis or low AMH levels for women, low sperm motility or testicular varicocele for men, there are fertility treatments available to help you still conceive. There are many medical and health-related issues that can affect fertility and ability to conceive.
Semen analysis as an integral part of infertility investigations is taken as a surrogate measure for male fecundity in clinical andrology, male fertility, and pregnancy risk assessments. Clearly, laboratory seminology is still very much in its infancy. In as much as the creation of a conventional semen profile will always represent the foundations of male fertility evaluation, the 5th edition of the World Health Organization WHO manual is a definitive statement on how such assessments should be carried out and how the quality should be controlled. A major advance in this new edition of the WHO manual, resolving the most salient critique of previous editions, is the development of the first well-defined reference ranges for semen analysis based on the analysis of over recent fathers. The methodology used in the assessment of the usual variables in semen analysis is described, as are many of the less common, but very valuable, sperm function tests. Sperm function testing is used to determine if the sperm have the biologic capacity to perform the tasks necessary to reach and fertilize ova and ultimately result in live births. A variety of tests are available to evaluate different aspects of these functions.
Semen is the yellow-white fluid that is released from the penis at the time of ejaculation. Semen is composed of seminal fluid and sperm. Sperm are the male reproductive cells that fertilize a female egg. A semen analysis will be performed on all specimens prior to cryopreservation. The analysis examines the color, viscosity how thick the semen is , and the time until the specimen liquefies.
