I will try to keep this as short as possible. Background follows, or skip right to the main questions below. My apologies. I am a 51 year old male. Went to ER for blood in stool (10 years post colon cancer) and found obstructing kidney stone. They did an abdominal CT. During the ER visit, I vaguely remember them mentioning pneumonia. After treatment and discharge, I got my CT report from patient portal and for the portion of the chest that was captured on the abdominal CT, it says "Tree-in-bud opacities as well as mild groundglass opacity partially imaged at the superior segment of the left lower lobe. Mild bronchiectasis is also seen. Elevated right hemidiaphragm." After Googling this, I thought it was worth checking out. I called the pulmonary department at Johns Hopkins, which is where I have been treated for 10 years. They said that they would review the records and call me back about an appointment. The scheduler called me and made an appoint for me six weeks out. Researched the doctor and the only thing he does is adult Cystic Fibrosis. After many hours of obsessive Google, I do have many of the symptoms.

My questions are:

1. How common / uncommon is it to be diagnosed at age 51? I have had 20+ cancer screening CT's in the past 10 years, and other than mild pleural thickening the past two years, nothing abnormal.
2. I have read that in something like 98% of males, the vas deferens is absent or blocked. I have three children and had no issues conceiving. Is that possible with CF or with a late adult diagnosis, does the reproductive not happen until later in life.

Thank you in advance for your help.
