I am 34 and have been married for 3 years. I am trying to conceived for the past 2 years without success. I am told that the baldness medicine, propecia, which my husband has been taking for the last few years could affect fertility, Is it true? A Propesia contains the drug called finasteride which acts by causing a decline in the male hormonal activity and thus reducing hair loss. Previous studies have shown that it does not affect male fertility. However, recent findings have indicated otherwise. This drug does cause infertility and sexual problems. By reducing the blood levels of the male hormone, testosterone it may result in the following: · Erectile dysfunction · Loss of sexual desire · Inability to ejaculate to reach orgasm. · Reduction in the sperm count · Poor semen quality Studies have also shown that after stop consuming the medication, sexual functions and sperm quality may gradually restored in most patients. As you are trying to conceive, it is advisable to discontinue the medication especially if his reproductive functions are compromised.

I have been smoking for the past 15 years. I just got married and intend to start a family soon. Can smoking affect my sperm? Will my wife’s fertility be affected also? She is a non-smoker. Yes. Smoking can negatively affect your fertility as well as your wife's. Research studies have shown that smoking is associated with: · Reduced sperm count: Sperm count refers to the number of sperm found in a measured quantity of semen. · Decreased sperm motility: Sperm motility indicates the swimming capabilities of the sperm. If sperm cannot swim properly, fertilisation of the egg will be affected. · Fewer normal shaped sperm: Normal shaped sperm is necessary for the conception of a healthy baby. · Increased incidence of damage to the sperm DNA: Sperm with damaged DNA may lead to problems with fertilization, embryo development and implantation, resulting in an increased risk of miscarriage. All these negative effects are attributed to the toxins found in cigarettes,the lower the zinc levels in the semen and the reduced production of male hormones by the testis. Scientists have also demonstrated that the effects of smoking are proportionate to the number of cigarettes smoked. The heavier the smoker, the worse the semen quality. But if he quits smoking, chances of successful fertility treatment may improve. A lower rate of success for IVF (in-vitro fertilization) treatment is found in couples if the male partner smokes. The miscarriage rate is higher and there are increased risks of birth defects and cancer in the offspring. Damaged sperm DNA is probably the cause. Fertility of the wife may also decrease because of the exposure to the second-hand smoke. The quality and quantity of the eggs are affected by the toxins in the cigarette smoke. One study found that second- hand smoke reduced the number of eggs retrieved in an IVF cycle by 46 percent. If you intend to start a family, you should stop smoking straightaway.

I am 31 year old male and have been suffering from gout for the past 5 years. I am on colchicine, a long term medication. Will the disease affect my sexual health and fertility? Gout is a condition where the joint is inflamed due to deposits of sharp, crystallized uric acid. Uric acid is a by-product when our body breaks down purines, the type of proteins found in some foods and beverages like liver, red meat, seafood, peas, and beer. Uric acid is usually absorbed in the blood, processed by the kidneys, and eliminated in the urine. But when we eat too much food containing purines or when the kidneys are malfunctioned and do not excrete the uric acid properly, it starts to accumulate in the blood. Eventually, this build-up leads to deposition of uric acid crystals in the joint causing pain, redness, heat, and swelling. The joint commonly affected is the big toe. But other joints in the knees, wrists, fingers, and elbows can be affected as well. Generally, gout does not affect sexual health and fertility. Occasionally, it can cause erectile dysfunction (ED) and the medication used in the treatment may result in infertility. Studies have shown that men with gout are at higher risk of developing ED. Should ED develop, it is also more likely to be severe. Scientists believe that the lining cells of the blood vessels in the penis are damaged by the high blood uric acid levels. Men with gout are also more likely to drink more alcohol, be overweight, or have medical conditions like diabetes, high blood pressure, heart disease, chronic kidney disease, and depression. All these conditions are linked to ED. Besides, pain from gout also makes sexual intimacy uncomfortable, further aggravating fertility issues. Colchicine, which is the drug of choice in the treatment of gout, can cause suppression of the production and maturation of the sperm and the egg. There are scientific reports suggesting that long term consumption of colchicine can lead to azoospermia (absence of sperm).

Pre-pregnancy check assesses whether the mother is fit to carry the pregnancy to term, whereas fertility health check examines the various fertility-related issues of the husband and wife and evaluates their fertility potentials. Fertility health check involves an in-depth interview of the couple on the age, duration of trying for a baby, frequency of intercourse, contraceptive method used, sexual history including exposure of sexually transmitted diseases, and lifestyle habits such as drinking and smoking. The man will also be asked on previous surgery or injury to the testes. The woman will be asked if she had previous termination of pregnancies, ectopic pregnancies, miscarriages, or previous pelvic surgery as well as the menstrual history. A physical examination of the couple will be done with special emphasis on the reproductive system. This is followed by a pelvic scan with ultrasound in the female. After the consultation, blood tests (including hormonal profile) according to the woman’s menstrual cycle will be taken and an appointment for semen analysis given. The results will be reviewed with the couple within 2 weeks of the first consultation. Additional tests may be customised depending on the profile of the couple. With the interviews, physical examination and detailed investigations and analyses of the results, the fertility potential of the couple can then be ascertained. If there are any cause of concern, fertility treatment options will then be discussed

I work near radars. Does the exposure affect fertility? Does it increase the chances of getting a male foetus? To understand how radio-frequency radiation emitted by the radar affects a man's fertility, it is important to know how sperm is produced . Sperm is produced in small coiled tubes in the testicles . These tubes packed like coiled spaghetti and number more than 750, may reach up to 50 cm in length when dissected out . Sperm takes about 72 days to grow and they are stored in another part of the testicle called epididymis. They remain there for about 15 to 25 days, mature and develop the ability to swim. If the sperm are not ejaculated, they eventually die and are absorbed by the body. In theory, radar irradiation can affect fertility in the following ways: · It can stop or slow the production of sperm. · It may change the shape of sperm . These sperm may have trouble swimming or lack the ability to fertilize the egg. · It can cause changes in the DNA of the sperm. Sperm with damaged DNA may not be able to fertilize an egg; even if it does fertilize the egg, the development of thefoetus may be affected resulting in a miscarriage or foetal abnormalities. Large research studies of the effects of radar irradiation on the sperm and fertility are very few . Some scientists found lower sperm counts in personnel exposed to radar, but others did not findsuch effect. Recent studies by researchers in China concluded that radar radiation inflicted damage to the male reproduction system by causing significant changes to sperm motility and shape, butsuggested that when the exposure stopped, the sperm quality would return to normal. Another study also found that navy personnel working with radar and/or sonar were more than twice as likely to have reduced fertility. Whether radar exposure would increase the chances of getting a male offspring, limited studies suggest that there is no such gender bias.

My husband was diagnosed as having diabetes 1 years ago. He is 35 and is on diet control with oral medications. Will diabetes affect his fertility? A. Diabetes can affect male fertility in various ways. They include: · Reduced sperm quality: Studies have shown that diabetes can cause damage to the genetic materials of the sperm. This will reduce the chances of fertilisation and increase the risks of miscarriage and foetal abnormalities even when conception occurs. · Erectile dysfunction(ED): Diabetes affects the nerve supply and blood circulation to the penis. This results in difficulty in getting or maintaining an erection. Some of the medications used in the treatment of diabetes may also cause ED. · Retarded ejaculation or delayed ejaculation: The loss or reduced sensitivity in the penis as the result of nerve damage from diabetes will lead to ejaculation problems. · Low testosterone levels in the blood have been shown in one out of four men with type 2 diabetes. This can lead to low sperm count, ED and decreased sexual drive. · Retrograde ejaculation: The damage to the nerve supply of the bladder muscles that control the opening of the urinary passage causes the backflow of the semen into the bladder. Hence,the sperm may not be able to deposit in the vagina during ejaculation.

I am 34 years old and trying to conceive. I am diagnosed as having type 2 diabetes. My doctor has been monitoring my blood levels of HbA1c which is 9.6 % at present. He told me I should wait a while till the levels drop to 6.5% or lower before I try to get pregnant. Why should it be so? What is HbA1c? What does the percentage represent? Keeping the blood sugar levels under control is very important for diabetic patients who are trying to conceive. This is because uncontrolled diabetes during pregnancy may have serious consequences affecting the baby such as miscarriage, premature birth, stillbirth and having a big baby requiring Caesarean section. When sugar is absorbed into the body from the food, it is circulated in the bloodstream as glucose . A certain amount of glucose gets attached to the haemoglobin, a protein in the red blood cell that carries oxygen. The compound formed is called “glycated” haemoglobin or HbA1c. The amount attached is directly proportional to the total amount of blood glucose present in the body and is expressed as a percentage of the total haemoglobin. As the life span of the red blood cells is 8-12 weeks, measurement of HbA1c is used to assess the average blood glucose levels over that duration. This provides a useful gauge of blood sugar control in diabetic patient. In healthy people, the HbA1c level is less than 6% of total haemoglobin. Your level of 9.5% is high and indicates that your diabetes is not well controlled. Studies have demonstrated that the complications of diabetes can be reduced or prevented if the HbA1c level can be kept below 6.5%. Since you are planning to become pregnant, you should be monitored with HbA1c monthly to help monitor your diabetes control. Meeting the target of 6.5% or below will help minimise the risk of the baby developing congenital malformations or ​other complications during pregnancy. As your level of HbA1c still high, you are advised to avoid becoming pregnant until good diabetes control is achieved and sustained.

My previous boyfriend infected me with gonorrhoea for which I have been treated. I am now married and have been trying to have a baby without success. Could the cause of infertility be due to gonorrhoea? Gonorrhoea is a common sexually transmitted disease cause by a bacterium Neisseria gonorrhoeae. It can infect both men and women. In many women, the infection can occur without much symptoms. The symptoms, if present, may include Painful or burning sensation while passing urine Increased vaginal discharge Painful sex Irregular periods Abdominal pain Fever Gonorrhoea can be treated successfully with antibiotics. But if left untreated or if the treatment is inadequate, the infection can cause serious consequences such as pelvic inflammatory disease. The bacteria can travel from the cervix (neck of the womb) up the womb to the fallopian tubes, causing inflammation and scars in and around the tubes. This leads to tubal blockage which prevents the sperm from fertilizing the egg resulting in infertility.

My wife and I have been married for 3 years with no children. We are trying to conceive. What are the nutrients in my diet that can boost my fertility? Eating a balanced and nutritious diet can boost your fertility by maintaining a healthy reproductive system. The following nutrients are known to help or improve sperm health. Vitamins: Vitamins are powerful antioxidants that protect the sperm from the damaging effects of free radicals, the unstable molecules linked with cell destruction. High levels of free radicals will affect sperm function and viability. The following vitamins are important for sperm health: Vitamin A is important in preventing sluggish sperm. It is found in leafy greens, carrots, red peppers, and apricots. Vitamin B : o Folic acid can boost sperm health. Food sources include liver, lentils, beans, asparagus, spinach, collard greens. o B12 has been shown to increase sperm counts. Food sources include fish, crab, clams, oysters, liver, beef, and eggs. Vitamin C has been shown to improve sperm quality, preventing them from clumping together, making them more motile. It is abundant in vegetables and fruits. Vitamin E is found in nuts, seeds, vegetable oils, leafy greens and fortified cereals Coenzyme Q-10 is a vitamin-like substance found in oily fish, like salmon and tuna, meats, and whole grains. Amino acid: L-carnitine is an antioxidant important for normal sperm function. It has been shown to help normalize sperm motility in men with low sperm quality. Food rich in L-Carnitine are found in meat, poultry, fish,nuts, seeds, and vegetables, including artichokes, asparagus, broccoli, Brussels sprouts, garlic and parsley. Trace minerals: Zinc is important for male fertility. Increasing zinc levels in infertile men has been shown to boost the sperm number and quality and improve its function. It can be found in oyster, shellfish, beef, pork, sesame seeds, pumpkin seeds or green peas. As zinc can be damaged by cooking it may be consumed by eating the food raw. Selenium is an antioxidant involved in the motility of the sperm. It is found in whole grains, lentils, fish, meat and eggs. Omega-3 fatty acids: Fatty fish like salmon and sardines are rich sources of omega-3 fatty acids. You can also get omega-3 in plant-based foods, like flaxseed, walnuts, canola oil, and fortified products such as eggs.

Are there any early “warning” signs that could indicate a potential fertility issue later on? Though not specific, some early warning signs that could signal a potential fertility issue later include the following: If the woman · Has very irregular periods, · Has menstrual pain which gets worse in severity and duration with time · Has smelly and yellowish discharge · Has persistent spotting in between periods · Has severe discomfort or pain during sexual intimacy · Has had abdominal surgery Or if the man · Has had many sexual partners before marriage · Has had Sexually transmitted infections · Has had previous surgery for hernia or undescended testis · Is a heavy smokers or alcoholic These are conditions that might affect the couple’s future fertility. They should go for early fertility checks. You can also check your “fertility potential” by doing a fertility index test (a self-test) on our home page.

I am 40 years old and have been married for 10 years with 2 children. Recently, I experienced some difficulty in erection. Will any change in lifestyle help me overcome this problem? I am not keen on taking medicine? You are suffering from erectile dysfunction (ED) or 'impotence.' This is the inability to keep the penis erect or firm enough for sexual intercourse. Don’t ignore it as this can be an early warning sign for more serious health problems such as diabetes and cardiovascular disease. There are many causes of ED. But the most common lifestyle-related causes are smoking, obesity and stress. Making lifestyle changes may improve ED and your overall health. These include: 1. Exercise regularly: A study from Harvard University showed that a 30- minute walk a day would reduce the risk of ED by 41%. Other studies suggested that moderate exercise helped obese men with ED improve their sexual performance. Kegel exercises, by strengthening the pelvic floor muscles, can improve erection. 2. Eat a well-balanced diet: In the Massachusetts Male Aging Study, eating a diet rich in fruit, vegetables, whole grains, and fish and reducing the intake of red and processed meats and refined sugar, lessened the likelihood of ED. Food fortified with vitamins, especially Vitamin B12, helps ED in older people. 3. Regular medical check-ups: Reduction of blood sugar, cholesterol, triglycerides and blood pressure have been known to help lower the risk of ED. 4. Maintaining a healthy weight: This is a good strategy for avoiding ED. Obesity raises risks for vascular disease and diabetes, the two major causes of ED. 5. Stop smoking and avoid excessive alcohol consumption. 6. Reduce stress: Learn how to relax. Give yourself some "quiet time "and get enough rest and sleep. This will help your body recover from stressful events and ED.

Q.I am trying to conceive for about 6 months I have been taking soya bean milk every morning and bean curd and tofu frequently, thinking that soy products are good for health. Recently, friends have been advising me to avoid soy products. How does soy affect fertility? A. Soy contains plant-derived female hormones called isoflavones. They have a very weak effect on human body and have been used in relieving  people with menopausal symptoms. Experimental animal studies have suggested that eating large amounts of soy might reduce fertility. But these results may not be applicable to the human beings. A few reports did suggest that high levels of isoflavones may decrease female fertility by interfering with the levels of pituitary hormones which stimulate the growth of the egg and ovulation. But the quantities of soy products eaten were extremely large and the statistics in countries in East Asia where soy products are consumed often showed that the birth rate is similar to, if not, were more than, in countries where soy is not normally consumed. Studies also did not find variations in fertility from soy consumption in healthy couples indicating that normal intake of soy is basically harmless.
