Why do males with Cystic Fibrosis have a very small chance of having kids?

Does cystic fibrosis affect males or females more?

There is an even distribution between males and females however the effects of cystic fibrosis effect them differently. Unfortunately the majority of males are infertile but women have more of a chance to conceive.

Which Organs does the cystic fibrosis effects the lungs?

Mainly the lungs and pancreas. For males it clogs tubes in the testes.

Does cystic fibrosis affect more males?

No, cystic fibrosis affects males and females equally. It is an inherited genetic disorder caused by mutations in the CFTR gene, which can be passed down from each parent who carries a mutated gene.

Is cystic fibrosis more common in boys or girls?

i copied the following answer from health.howstuffworks.com Unlike some other genetic conditions, cystic fibrosisoccurs equally as often in men and women. The genetic mutation for cystic fibrosis occurs on chromosome 7 and is not impacted by gender. The severity of symptoms related to cystic fibrosis, however, does vary in men and women. In particular, girls with cystic fibrosis have more difficulty with meeting growth milestones and experience more lung-related problems compared to boys. Due to these more severe symptoms, women with cystic fibrosis have shorter life expectancies than men. It is estimated that men with cystic fibrosis live four to five years longer than women with cystic fibrosis, Moreover, under the age of 20, girls have a 60 percent greater chance of dying due to cystic fibrosis complications compared to males [source: Cystic Fibrosis Worldwide]. As a result, the prevalence of male adults with cystic fibrosis is greater than the prevalence of female adults with cystic fibrosis, suggesting a male advantage with the disorder. Cystic fibrosis researchers argue that this gender difference is the result of early-onset lung infections in girls. Girls appear to develop these infections earlier in life than boys, leading to more severe cystic fibrosis complications, and even death. Girls also appear to have greater difficulty maintaining a healthy body weight after puberty compared to males, which places girls at greater risk for cystic fibrosis complications. It appears that this gender gap can narrow if girls are provided with more intensive medical care. In fact, girls and women who receive regular intravenous antibiotics, regardless of their condition, have improved survival rates [source: Cystic Fibrosis Worldwide]. As a result, countries with excellent health care, such as Scandinavian countries, do not have a difference in the survival rate of men and women with cystic fibrosis. i hope it helps:)

Cystic fibrosis autosomal dominant?

hey I'm not positive but I believe that Cystic Fibrosis is autosomal. My reasonning for this is that there seems to be an equal number of females that have cystic fibrosis as there are males. I AM NOT POSITIVE.

Is cystic fibrosis sex or gene linked?

Cystic fibrosis is primarily a genetic disorder caused by mutations in the CFTR gene, which is located on chromosome 7. It is not sex-linked, as the gene responsible for cystic fibrosis is not located on the sex chromosomes (X or Y). Both males and females can inherit the condition if they receive two copies of the mutated gene, one from each parent. Therefore, cystic fibrosis is considered an autosomal recessive disorder.

What is survival rate for Cystic Fibrosis?

Cystic Fibrosis is a life threatening genetic disorder. More children are living into adulthood with better treatment options. The death rate is 100 percent, when the lungs and pancreas quit functioning.

Why are the sperm tubes of males blocked because of Cystic Fibrosis?

There is a lot of mucus build up in those tubes which does not allow for the tubes to be clogged.

Is cystic fibrosis sex-linked?

CF is a serious and chronic disease of the lungs, it has nothing to do with sex, except that it can affect both males and females.

Why does cystic fibrosis make people infertile?

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.

Why Males having a greater chance of hemophilia?

Hemophilia occurs in the X chromosome, and males are the genders that have the X chromosome.

How can a child with cystic fibrosis have two parents that do not have cystic fibrosis?

The parents will both have a specific gene defect. If they do there is then a 1 in 4 chance of them having a child with cf. so if you are considering having children you should have a blood test to find out if you are a carrier of the gene causing cf. hope that helps.
