Coping with Infertility
Coping with Infertility
There is an alarming increase in the number f childless couples in India. but they need not lo lose hope!
by AMresh k Tiwary
| According to a recent survey conducted in nine Indian cities, out of the 2,562 people who participated in it, nearly 46 percent were found infertile. Results from another parallel survey conducted among 100 infertility specialists showed that nearly 63 percent of the infertile couples belonged to the child-bearing age (31-40). |
As life runs on the fast lane, a monster called infertility slowly makes inroads into the lives of urban India giving more and more young couples sleepless nights and problems in having a child.It is rather ironic that from a time when family panning drives launched in the 1970’s were the Government’s prime focus, the country has come to a point where suddenly young and modern India seems to be caught in the ever-increasing problem of infertility.
A trip through the infertility roller-coaster seems inevitable for many such hard hit couples who soon after marriage realize how uphill a task getting pregnant can be nowadays! With the crisis brewing at a rapid rate, almost 30 million couples in the country suffer from infertility, making the incidence of infertile couples to be 10 percent. Today, the number of Indian couples turning to artificial methods to conceive has gone up considerably.
However, keeping infertility at bay is not impossible at all and all that is required is pursued tenacity, consistency and will in our day-to-day activities. But before we go any further to delve deep into the problem, it is important to understand what exactly is infertility and how does one define it?
Every human being wishes to procreate and historically infertility has been like a curse for any individual affected by it. Couples may find it difficult to conceive naturally due to different reasons. The ART (Assisted Reproductive Technology) consists of a comprehensive programme that is offered to such couples.
Explains Dr Sonia Malik, programme director, Southend Fertility and IVF, New Delhi, and president, Indian Fertility Society, “Assistance can be given to both men and women depending on the cause of infertility. Infertility management involves detailed investigations to reach a logical diagnosis and then specific treatment. Infertility centres provide comprehensive infertility management/ART programme to patients. The various forms of treatments like Intrauterine Insemination (IUI), In Vitro Fertilization (IVF), Third Party Reproduction and Intracytoplasmic Sperm Injection (ICSI) are in vogue these days.”
Intracytoplasmic sperm injection (ICSI, pronounced “eeksee” or “icksy”) is an in vitro fertilization procedure in which a single sperm is injected directly into an egg. The technique was developed by Gianpiero Palermo around 1991 in Brussels. Today it has become the treatment of choice for men with weak sperms that cannot travel themselves into the egg.
Approximately 40% of infertility in couples can be attributed to male sub fertility. ICSI has raised hopes of these couples. This method of treating predominantly male-factor infertility has been a breakthrough, and it has established itself as the preferred method of treatment in the field of assisted reproduction.
When can ICSI be performed?
ICSI is an amazing procedure that can be performed with ejaculated sperms or even with sperms retrieved from the epididymis or testis! Men with obstruction in their passages can father a child by using their own sperms that have been extracted by a surgeon. ICSI can also be offered to patients of previous IVF failures due to failed fertilization and patients with unexplained infertility. ICSI is different from conventional insemination since we clean away the follicle cells from around the eggs and an embryologist chooses the sperm to be injected. A small number of eggs do not tolerate the injection procedure and you can expect that about 5% of eggs die as a direct result of ICSI. However, fertilization rates, embryo quality and pregnancy rates are the same as for couples who do not have ICSI.
How is ICSI performed?
The process involves the injection of a single sperm within the ooplasm of the oocyte. Following the first ICSI birth in 1992 thousands of babies have been born around the world. Sperms for ICSI can be obtained from ejaculation, even when only few are present, or through surgical retrieval from epididymis or testis.
Microinjection is normally performed under a specialized microscope with the aid of a micromanipulator which allows small movements under high magnification. The scientist/embryologist sits on the ICSI station, looks either directly into the microscope or at a monitor that magnifies the image and then injects the egg by moving two manipulators that look and function like joysticks. He holds the oocyte with one hand and injects through the other.
IVF
Reproduction is the process wherein there is fusion of the male and female gametes resulting in the exchange of genetic material, thus forming a new individual with an entirely different genotype.
Mammals reproduce through sexual reproduction but technology now allows mammals to reproduce “asexually” through the process of in vitro fertilization. In this technique, the entire process of fertilization takes place outside a woman’s body. This involves extracting a woman’s eggs, fertilizing the eggs in the laboratory with sperm, and then transferring the resulting embryo (s) into the woman’s uterus through the cervix (embryo transfer) where it can develop. Most couples transfer two embryos; however, more may be transferred in certain cases. IVF is the most common form of ART and it is often the treatment of choice for a woman with blocked, severely damaged or absent fallopian tubes.
Evaluation and preparation of a couple
Proper evaluation of infertile couple before IVF is very important for the success of IVF and prevention of complications. Any ART procedure should be preceded by traditional fertility workup and at this stage it should be decided whether ART should be instituted, postponed for other treatment modalities or refused to the couple. Once the patient has been selected to undergo ART treatment, thorough testing of patient should be undertaken to correct any problems which may lead to IVF failure. At this stage, it should also be decided whether specific procedure such as egg, sperm or embryo donation is required.
Infertility is defined as difficulty in conceiving or becoming pregnant, despite having regular sex without contraception for two years in a row. The time a couple takes to conceive could vary from days to months. Also earlier infertility was largely seen as only ‘a female problem’ with women easily becoming the target of social scorn.
Dr Gauri Aggarwal, Fertility Specialist, Yashoda Super Speciality Hospital, Ghaziabad, says, “Such a theory no more exists and the time when women were solely battling the blame for being barren has become a part of the bygone era! There have been enough research revelations that have attributed the male for the cause of infertility and there is a general realization that implicating a woman with prejudice would only result in robbing the root cause of the issue. Now, one in every five men between the age group 18-25 is found to suffer from low sperm count – one of the main cause of infertility.”
With the problem having become widespread what are the reasons one may ask? Irregular and low sperm count, hampered sperm delivery and poor motility of sperms are prominent causes of infertility in men. Some other medical reasons such as obesity and lifestyle disorders that includes diet imbalance, addiction to smoking or alcoholism, sedentary existence, or mental and emotional stress also contribute to poor sperm count.
Dr Sonia Malik says, “On the other hand, polycystic ovary disease (PCOD), a condition characterized by excess production of hormones and lack of ovulation coupled with hectic lifestyle and job stress lead to conception problem amongst women. Primary ovarian insufficiency (POI) is another cause of ovulation problems. POI occurs when a woman’s ovaries stop working normally before she is 40. Other than the above changing lifestyle patterns, strenuous work schedules and stressful surroundings are some major reasons responsible for tilting the scale towards the inability to conceive. With an increase in stress and fatigue men and women often suffer from a steady decrease in the libido which has lately become an issue of concern for many.”
Having said that all is not gloom and to enable a hassle-free normal pregnancy it is prudent to adhere to certain precautionary measures on a day-to-day basis. The general preventive measures like maintaining weight, avoiding cigarettes, alcohol, reducing stress, increasing intake of nutritious diet, though very vital, may sound clichéd, but, certain factors that impact fertility in both men and women are being ignorantly dismissed.
High testicular temperature is increasingly attributed as a cause for male infertility. Scientific studies have indicated that prolonged use of mobile phones can significantly affect male infertility. Exposure to any type of intense and prolonged radiation is known to harm sperm production.
Although ovaries in women are protected in the interior of their body, testisis located outside, not for aesthetic reasons, but for functional ones. Testicular temperature should be lower than the body temperature and anything distorting this may harm male fertility.
Thus, it would be wiser for men to wear loose underwear and pants and have frequent breaks when working in the sitting position continuously. Resting laptop computers on lap raises the scrotum’s temperature, say researchers, and hence it is better to avoid using mini computers on laps literally!
Though physical exercises are imperative, great caution is required especially when it comes to specific sports where testis is not properly protected in men. Testicular injuries must always be treated without any delay lest it may result in long-term consequences on fertility.
According to Dr Sowjanya Aggarwal, infertility & IVF specialist,Max Super Speciality Hospital, Vaishali, another issue of concern is the declining libido among urban couples which has emerged as one of the main causes that has come to engulf couples living in the cities. Hectic schedules, poor work life balance, constant tension and increase in travel time leading to low levels of libido and less sexual activity among couples comes across as the biggest hindrance in conceiving nowadays. As stress levels are usually high among urban couples, poor eating habits and increase in medical conditions such as diabetes lead to lack of quality and quantity of sperms and eggs. Thus habits such as smoking, tobacco consumption, frequent drinking, unhealthy food habits and no exercise need to be immediately done away with.
It could also be shocking to know that products like furniture polish, all-purpose cleaners, bug sprays, bathroom cleaners and room deodorizers may contain chemicals that could diminish conception by 33%. Organic, non-toxic alternatives are anytime a better option.
Dr Sowjanya Aggarwal said, “Paint thinners, household glues and oil paints can be toxic and negatively affect fertility increasing risk for miscarriage when pregnant. If a ‘sniff test’ indicates strong and offensive smell it’s only better to avoid them. Women should be wary of paraben, a preservative found in most of the cosmetics, from shampoo to moisturizers to lipsticks. Parabens belong to a group called xenoestrogens, or false estrogens that could induce infertility”.
Cow’s milk, especially that which is milked when the animal is pregnant is rich in fertility enhancing hormones. Plastic needs to be avoided. Hormones leach more when unhealthy plastics are hot and wet. And finally, a good sleep is the most ideal as 80 per cent of ovulation occurs between midnight and 4 am. Interrupted sleep could weaken immunity, disrupt reproductive hormone levels and hinder ovulation.
Scheduling the doctor’s appointment periodically is the best thing to do to assess your current fertility status and address any problems before you start trying to conceive. For those not being able to conceive despite years of effort, Assisted Reproductive Technology or artificial means of conception can come as a huge rescue.
In case of male infertility the treatment options available are medical – with hormones, multivitamins and antioxidants which give results for a period of three months and surgical through varicocele ligation in properly selected cases; IUI (Intrauterine Insemination) and IVF or In Vitro Fertilization in the case of women. But it is pivotal to consider the age factor as the older you are, the more difficult conception is.
Male infertility programme
The last century saw rapid advances in the management of the infertile male both in diagnostics and treatment. The WHO gave guidelines for a proper semen examination and based on that treatment was decided.
Today, male infertility programme involves not only the standard testing procedures like semen analysis but also special tests to determine the fertilizing potential and quality of the sperm. This is called the DNA fragmentation test. Occasionally, we find that all sperms in a sample are non–motile but we are not sure of its viability. In such cases, we carry out the HOS test. In patients who are azoospermic on testing, testicular fine needle aspiration is undertaken. If this too does not show sperms in the sample, we proceed to a testicular biopsy. The sample is checked for sperms and if positive, it is frozen or cryopreserved till the wife is readied for ICSI. Men who have mild infertility can be offered IUI but those that have weak sperms are treated by either IVF or ICSI and recently IMSI.
Third party reproduction
Third party reproduction refers to the use of oocytes, sperm, embryos or uterus that has been provided to a couple/single individual (called intended parents) by a third person (donor) in order to help them/him or her to become a parent.
According to the present Indian guidelines on ART drafted by the ICMR, all donors except the surrogate need to be anonymous to the commissioning couples. The ICMR guidelines also state that this activity of supplying various gametes and surrogates will not be carried out by the IVF centre but separate entities called ART banks. All the legal issues are also the responsibility of these banks. Once the requirement is fulfilled, the medical fitness of the donor is assessed. After fulfilling the various formalities, the couple and their donor/surrogate is taken into the third party programme.
Recurrent pregnancy loss programme
There is nothing more painful than losing a pregnancy repeatedly! It is not only devastating for the patient but also the treating doctor. RPL is defined as a situation where a woman has lost three or more than three pregnancies. In fact, RPL may be caused by chronic infections like genital tuberculosis.Majority of recurrent failures whether at implantation or later pregnancy is due to an impaired blood circulation within the pelvis, especially the uterus. The cause for this may vary.
Doctors carry out tests to rule out the cause of RPL and accordingly treat the patient. In case the patient has a genetic cause, the patient and her husband are informed regarding the defect and counseled regarding future implications. Endocrinal causes like PCOS can also be the reason and needs to be tackled by taking insulin lowering medication. There is no need to go through extensive testing after a single pregnancy loss. This could have happened by chance and one should not worry about it.
“The time when women were solely battling the blame for being barren has become a part of the bygone era! There have been enough research revelations that have attributed the male for the cause of infertility and there is a general realization that implicating a woman with prejudice would only result in robbing the root cause of the issue. Now, one in every five men between the age group 18-25 is found to suffer from low sperm count – one of the main cause of infertility.”

Interview
“There should be strict guidelines regarding sperm donors”
Dr Sonia Malik, President of the Indian Fertility Society and Programme Director of South End Fertility & IVF, is one of the pioneers of fertility treatments in North India with her first centre at Holy Angels Hospital, Vasant Vihar, New Delhi, starting in 2001. With over 10,000 IVF cycles, Dr Malik has successfully been able to bring the joy of parenthood to several couples from India and abroad.

Dr Malik has a keen interest in academics and is also the chairman of the Infertility Committee, FOGSI (Federation of Obstetricians and Gynaecologists Society of India). She is a scientific collaborator at the Reproductive Research Centre, Cleveland Clinic, USA. Dr Malik has also served as the past president of the Indian Menopause Society.
With a degree in medicine from Rohtak Medical College, Dr Malik went on to gain international experience in Iran and Saudi Arabia before setting up her practice in Delhi. Her areas of interest are reproductive endocrinology, reproductive immunology, genital tuberculosis and premature ovarian failure. Under her guidance, Southend Fertility & IVF has a strong presence in Delhi and NCR and is now opening centres across North India.
Childless women in several countries are looking for fertility clinics abroad due to several problems they place in their own countries. With a young population, India can meet the demand. If we can embrace organ transplant, why can’t we have sperm banks? Dr Sonia Malik,speaks about such challenges to Double Helical.
Q: Do you think it is morally wrong to donate sperms?
Ans: It is ethically as well as morally correct to donate sperms provided it is done in the right manner following all the rules and regulations. There is no harm in helping others realize their dream.
Q: What kind of rules and regulations come into play when one goes to donate his sperms?
Ans: We need to follow all rules and regulations strictly because it is very important for the recipient couple as well as for the offspring born as a result of sperm donation. The donor should be medically, physically and mentally fit and free of any disease so that the offspring born is healthy. At the same time, all the legal and confidentiality issues should be given due importance and consideration.
Q: What should health regulators and policy-makers do in order to bring about necessary policy changesto facilitate sperm donation?
Ans: There should be strict guidelines as to who can be a sperm donor and for how many times and these should be strictly adhered to. All the required medical tests should be done and all the samples should be routed through the proper authorized sperm ART banks after the quarantine period is over.
Q: Do you think India can fill in the sperm shortage gap in countries like Britain and the US, suffering from such shortages? Please explain.
Ans: Yes, India can fill in the gap merely because of population ratio. But why is there a shortage of sperms in other countries? Is it because of strict rules there or apprehension of people to donate sperms there?If that is so then what are the reasons of apprehension there and free availability of sperms in India? The policy-makers must look into that. No rules and regulations should be violated.
Q: Generally, donors are paid for donating sperms. How is the amount paid?
Ans: The amount varies from place to place and in my knowledge it ranges from Rs 500 to Rs 3,000. The variation is mainly because of their looks and educational qualifications.
Q: Sperms are a major source of infections, including HIV/AIDS. So, what are the vital things to be kept in mind while sourcing them?
Ans: Before taking the sperms for donation one should be very sure about the medical history and screening of the donor with regards to all the viral markers. Preferably they should be repeated after at least 3 months and then the sample released so as to be sure of the window period.
Q: How do you differentiate healthy sperms from the unhealthy ones?
Ans: Healthy sperms are the ones where the semen analysis fulfils all the criteria set by the WHO for count, motility, morphology etc. Semen should be free of any infection. Of course, if we come to know whether the donated sperms have ultimately resulted in a pregnancy then they are the healthiest sperms.
Q: Do you think the youth should donate sperms? How would you encourage them?
Ans: It is entirely a personal decision and how one looks at it because sperm or egg donation is not comparable to something like blood donation where a stronger message can be sent across. One can guide the youth and counsel them or make them more aware through social media like the movie Vicky Donor did.
