As long as the working apparatus is in order, most men assume themselves capable of fathering a child - and that’s a fair assumption, says obstetrician and gynaecologist DR CHRISTOPHER NG, whose fertility clinic offers help for the 15 percent of couples who experience problems in this area. In half of these couples, male infertility can be a contributing factor.
Apart from the well-known culprits alcohol, tobacco smoking and obesity, here are some other possible causes - an unlucky 13 of them:
To determine the cause in a particular case, scrotal ultrasound scanning, hormonal tests and chromosomal analysis are used. Semen analysis measures the number of sperm present and looks for any abnormalities in their shape and movement, also screening for sperm infections.
Surgery can correct a varicocele or repair an obstructed vas deferens, explains Dr Ng, and vasectomy can be reversed. In cases where no sperm are present in the ejaculate, sperm can be retrieved directly from the testicles or epididymis using sperm retrieval techniques as part of the IVF procedure. Sperm infections should be treated with antibiotics. Medication and counselling can improve erectile dysfunction or premature ejaculation, as can hormone replacement therapy, while multivitamins (A, C and E), zinc and l-carnitine can improve sperm quality and motility respectively. In the end, the couple may require assisted reproductive technology treatment; various forms of this are available.
