Dear Dr G, I have turned 60 and am a healthy chap who exercises and watches his diet regularly.

Dear Dr G, I am a 66-year-old man starting a new relationship. Despite entering my later years, I refuse to slow down and engage in my career and exercise regularly to stay healthy.

Infertility is defined as the inability of couples to conceive after one year or more of active sex without contraception.

Dear Dr G, I read with interest last week's article on the "reversal of misfortune in infertility". My wife and I do not have any fertility issues, but we are reconsidering our family planning and hope you can help.

Dear Dr G, My wife and I have a dilemma in life, and we are hoping for a solution.

Dear Dr G, My wife and I are both in our early thirties. We have been trying for a baby since we got married three years ago but there has been no positive outcome.

Dr G talks about the Intrauterine Contraceptive Device (IUCD).

Dear Dr G, I hope to put Dr G on the spot to mediate our dilemma in deciding who should take on sterilisation as the final chapter of our family planning. My wife and I are in our early forties and blessed with two teenage kids.

Dr G talks about the withdrawal technique as a form of contraception.

I am a firm believer in safe sex. Not that I am promiscuous or worried about sexually transmitted infections but my primary concern is contraception and avoiding unwanted pregnancies.

I understand that, as a urologist, you tend to answer questions related to men's health. However, I hope you can take the opportunity to discuss contraception.

Dear Dr G, I am writing to you burdened by guilt over my past sexual encounters, hoping you can help me resolve this remorse.
