Let's now explore this window further to find out when was the best time.The egg once released have a lifespan of twelve (12)hours. The egg therefore, needs to be fertilized in this twelve- hour period for conception to occur. The sperm on the other hand can survive as much as 5 days in the reproductive duct. Unhygienic sexual practices can lead to pathologic conditions like urinary tract infection. Langer-Giedion syndrome just isn't normally genetically inherited. It happens as a result of random occurrences during the advance of either eggs or sperm in a parent of the affected individual. There is no previous history of the syndrome inherited line. In rare cases, individuals inherit the chromosomal deletion coming from a parent who has this issue. Langer-Giedion syndrome can be an autosomal dominant condition since just having one copy of the mutated chromosome 8 in each cell is enough to contain the disease.
