Q. Can hypogonadism become a problem in younger men? What are the symptoms of hypogonadism in men?

A. Hypogonadism in males, a condition with many possible causes, is due to decreased function of the testicles. Male hypogonadism causes impaired sex hormone (androgen) production and sperm development. Its manifestations are determined primarily by the age of onset.

Q.I am allergic to the latex in condoms. What do you suggest I use to have safe sex? I need something that will work. I have always been told to use lambskin, but I am scared that it isn’t going to protect me well.

During intercourse, semen is ejaculated into the vagina, where the sperm can then travel through the cervix and uterus up into the Fallopian tubes to fertilize an egg. In some cases, the egg is already in the tube awaiting fertilization; in others, the sperm (which can live for up to 72 hours) wait in the Fallopian tubes for an egg to be released.
