Taking some 'extreme' examples of semen analysis parameters will help put the probability of conception of infertile couples in perspective. About half of couples unable to have children have a male infertility problem. The analysis will also help determine if low sperm count or sperm dysfunction is the reason behind infertility. Aitken and his group many years ago demonstrated a correlation between sperm movement characteristics and sperm fertilizing ability as evaluated by the zona pellucida-free hamster egg penetration test. Despite the sometimes dramatic changes in concentration, this man's intrinsic fertility potential was unchanged. It is not been convincingly demonstrated that sperm morphology correlates with the ability of couples to conceive with either sexual intercourse or intrauterine insemination IUI.

No prior fertility history. First, the semen must be kept at body temperature. Often the test needs to be repeated so the initial abnormal result can be confirmed. While a decrease in morphology can be associated with a decreased probability of conception, this is one instance in which there is probably no effect on the chances of conception and the morphology can be safely ignored. Laboratories performing sperm "counts", in general, vary in the details that they provide the physician requesting the "count". Results for at-home tests are usually available within 10 minutes. There are 44 autosomes and two sex chromosomes.
FertilityIQ: Sperm How to Interpret the Semen Analysis
The technique could one day be used to treat male infertility. Semen analysis Quality statement Services analysing semen samples use methods and reference values in accordance with the most recent World Health Organization laboratory manual. Many couples experience problems with infertility when trying to conceive. A normal result is more than 5 sperm penetrations per ovum. Increased risk of cancer among azoospermic men.
Briefly, volume is the amount of fluid that comes out when a man ejaculates. Sometimes, a macroscopic examination of a sperm specimen shows a high percentage of round cells in addition to sperms. Where SCSA is felt to be potentially helpful in resolving a problem or answering a clinical question, arrangements to obtain the test are carried out. Definitions of terms used in this quality statement Reference values The results of the semen analysis conducted as part of an initial assessment should be compared with the following World Health Organization reference values: Testicle Biopsy A testicular biopsy can be used to diagnose lumps, causes of infertility, and obtain sperm for in vitro fertilization.
