Your 6th house (of health) is ruled by Capricorn....... showing that you may have some troubles with skin, hair, nails, knees, legs, bones/skeletal system, and/or your back (all governed by Capricorn).
Capricorn is ruled by Saturn, and your Saturn is in your 2nd house in Libra ---- which indicates also, that you could be experiencing issues with diabetes, ovaries/prostate, kidneys, veins, or buttocks
(all ruled by Libra).
It also suggests that any kind of treatment(s) you may have could be very expensive!
Is any of this the issue that you're dealing with right now?
Regarding fertility, as requested; your 5th house (of children) is ruled by Sagittarius and also holds your Mars in Capricorn.
Ruler of Sagittarius is also in your 2nd house, Jupiter, and is Squaring your Mars -------- which suggests that there may be some issues regarding fertility, or that you are consciously putting off having children (possibly, again, due to finances which the 2nd house is responsible for..) Or when you do have children, it could cost you much money to take care of them.
Also, if you are a man, that your sex-drive and/or anger, if not properly maintained,
could negatively impact your life financially.... (think law-suits, etc, as Jupiter rules over Law). If you are a woman, Mars squaring Jupiter could show that you have troubles with men in your life... as in you may feel that you attract men who arent very positive.
In any case, because you also have Saturn Squaring Mars, you may feel restricted sexually.. which inhibits your ease of having children.
Though there is still hope that you may have children! But it may take more active work on your part to make it happen, and parenthood may possibly come at an older age than the majority.
