Over 95% of males with cystic Fibrosis are infertile. There are 3 reasons why this is true. 1) Often, the males lacks the pretense of his vas deferens, the tubes which move sperm from the testicles to the penis. 2) At other times, the vas deferens is blocked, and sperm are unable to pass through. 3) Finally, when there is a sufficient opening for the sperm to pass through, the sperm are insufficiently mobile and cannot make their way through the vaginal tract to the female egg.

How did Celine Dion make Canada a better place?
She doesn't make Canada (the country) better. She has made the lives of some Canadians (particularly those with cystic fibrosis) better. Celine has a personal connection to people affected by cystic fibrosis, as her niece Karine died at the age of 16 from it.

Can you get Cystic fibrosis?
Cystic fibrosis is a genetic disease and can only be inherited through genes. It all depends on your parents alleles. Let's say that the allele for cystic fibrosis is c. If your Mum has the allele Cc it means she is hetrozygous. If you Dad has the same allele he is also hetrozygous. When they had children, the two small c's could come together to make a child with the alleles cc. (This means that the child has cystic fibrosis and has homozygous reccessive alleles.) When they had children their alleles could also come together to make CC (homozygous dominant- this means that person doesn't carry an allele for cystic firbrosis and will never get it. This means that if that person had children with another person who has the alleles CC, their child wouldn't get it), or it could make a child with Cc alleles. The child with Cc alleles wouldn't get cystic fibrosis because the allele big C (dominant allele) over powers the allele small c (reccessive- the cystic fibrosis allele). Although this person doesn't have cystic fibrosis their children might because they carry the allele for cystic fibrosis, which is c.

What two parts of the body are affected by cystic fibrosis?
cystic fibrosis means there is too much fluid in the lungs and it makes it very hard for them to breathe. It also affects their growing and their digestive system because of the mucus. Unfortunately even a small cold can make them very sick because it affects the lungs. Unfortunately they usually die in their 30's and it is a very serious disease that more people need to be educated about.
How can you get cystic fibrosis?
For a baby to be born with Cystic Fibrosis, both parents must be carriers of the faulty CF gene. Where both parents carry the faulty gene, each child has a one in four chance of having CF, a two in four chance of being a carrier and a one in four chance of not having any CF genes.
Can Cystic fibrosis be prevented?
Cystic Fibrosis cannot be prevented. It is an inherited disease, so there is no possible way to prevent something inherited. One parent will be a carrier and so will the other parent, therefore resulting in the child having CF.
How do you explain cystic fibrosis to your seventh grader?
tell your child that its mucus in the body that is very hard to get rid of, and it will make one very sick
Why are people infertile?
They are many reason why people are infertile of them it is radiation.Long time radiation for any reason can make males infertile.Other causative agent can be genetic or physiologic. Using testosterone can make males infertile.
Is fibrosis residual a disease?
Cystic fibrosis is not a communicable disease , it is classified as a noncommunicable disease because it is a hereditary disease.
Is cystic fibrosis controlled by a dominant allele or by a recessive allele?
It is controlled by a recessive allele. The gene encodes a chloride ion channel that is required to make sweat, mucus and a few other things. One copy of the gene is sufficient to prevent cystic fibrosis, and it is only when both copies are defective that the person would have the disease and show symptoms.
How does a person inherit cystic fibrosis?
For a baby to be born with Cystic Fibrosis, both parents must be carriers of the faulty CF gene. Where both parents carry the faulty gene, each child has a one in four chance of having CF, a two in four chance of being a carrier and a one in four chance of not having any CF genes.
