India will overtake China as the world’s most populous country by 2023, equal to data published by the United Nations in July 2022. Going further, India is expected to raise this gap. By 2050, China’s population is expected to fall to 1.317 billion (from 1.426 billion by the end of 2022), while India will touch 1.668 billion (from 1.412 billion by the end of 2022).
While these figures are concerning, there is moreover some good news on the horizon. India’s lineage rates have once dropped significantly. Since 1990, India’s total fertility rate (TFR) has halved. Equal to the OECD, TFR refers to “total number of children born to each woman if she were to live to the end of her child-bearing years and requite lineage to children in structuring with the prevailing age-specific fertility rates.”
Moreover, India’s total fertility rate currently stands at two, which is unelevated what they undeniability the replacement level (2.1), as per the National Family Health Survey.
In other words, India’s population will not only stabilise but fall given that new births will not be worldly-wise to match deaths. Of course, there are significant inter-regional variations, but this data does seem to indicate the significant progress of population tenancy measures in India.
As one of the first countries to introduce an official programme of lineage control, the Indian state has long recognised the need to stabilise and reduce our population. Having said that, the Indian state’s history with population tenancy has been a mixed bag at best.
The worldwide refrain is that overpopulation has held when India’s developmental aspirations. While this vein has led to some positive developments, there have been some egregious errors and violations withal the way with Indian women largely validness the brunt of state action.
However, one of the standout results of India’s population tenancy policy was the emergence of Saheli (Centchroman), the world’s first non-steroidal lineage tenancy pill, launched in 1995 under the National Family Welfare Programme. The pill was the product of two decades of rigorous research led by Dr Nitya Anand, a prestigious organic chemist, at the Central Drugs Research Institute (CDRI), Lucknow.
As a pill that was to be consumed once a week, this oral contraceptive drug gave many Indian women the self-rule of choice. Here’s the unenduring story of how this happened and the scientist overdue it all.
The first pill
Unlike implants, condoms or surgical sterilisations, lineage tenancy pills, which interfere with the biological processes involved in pregnancy, are the least intrusive and most constructive as well.
In 1951, Carl Djerassi, an Austrian-born Bulgarian-American pharmaceutical chemist, and his colleagues George Rosenkrantz and Luis Miramontes, ripened the first lineage tenancy pill. This was a revolutionary step in the history of population tenancy considering it helped millions of women make their own decisions well-nigh pregnancies.
According to an explainer by D Balasubramanian in The Hindu, “What this pill does is to inhibit ovulation or the release of the egg. Additionally, it moreover tends to make the vaginal fluid thicker and increasingly viscous. As a result, the sperm from the male is unable to meet the egg and fertilise it. An important point well-nigh using the pill is that it must be taken daily.”
If the subject does not take the pill for two weeks, it could result in pregnancy upon sexual intercourse. However, this pill has a series of side effects including nausea, gory between periods and other potential complications considering it contains a steroid component.
But there was telescopic for largest quality pills. Fast forward to the 1960s, and the Government of India, tabbed upon its scientists to develop alternatives. Stepping up the plate, Dr Nitya Anand and his team at CDRI, Lucknow, began developing solutions.
Studying past publications, they discovered a molecule tabbed ethamoxytriphetol (also known as MER-25), which among other things, exhibited “anti-fertility effects in animals”. However, this particular molecule did not possess the relevant potency and had some serious side effects.
Undeterred, Nitya Anand and his colleagues began developing flipside solution. Equal to Balasubramanian, Nitya Anand and his colleagues started “with MER-25 as the base, synthesised a variety of molecules and tried each of them for antifertility activity”.
“After several attempts, they hit upon the right candidate in 1971. Its chemical structure is shown in the twin figure. Since it belongs to the chroman family and was made at the Central Drug Research Institute, they christened it Centchroman,” widow Balasubramanian.
In a increasingly detailed explainer, the Council of Scientific and Industrial Research stated:
Among several chemicals/compounds, Centchorman (Ormeloxifene) was derived from benzofuran and ethamoxytriphetol (alias MER-25) compounds as an orally taken lineage control/family planning drug without several years of perseverance and nonflexible work of Dr Nitya Anand & team in 1971. The Centchroman was tested in laboratory experimental animals, rats, dogs, and monkeys for preclinical (before human use) contraceptive purposes. Further, the preclinical harmful effects/toxicity have moreover been tested on laboratory experimental animals such as rats, beagle dogs, rhesus monkeys, and rabbits and found safe. There were several clinical trials (safety of a drug or chemical) on women surpassing it was tried for unstipulated population use by the then competent validity of India Drug Regulatory Guideline in 1990.
In unrelatedness to the pill ripened by Djerassi, the Centchroman was to be taken weekly since it remained well undivided in the soul for many hours. The pill ripened at CDRI moreover does not disturb a woman’s hormonal wastefulness since it does not stupefy ovulation. What the pill does is prevent the process of implantation (when a fertilised egg attaches to a woman’s uterine lining). Going further, the pill can be taken without sexual intercourse. It possesses no steroidal component (thus possessing none of the associated side effects), and if a woman chooses to discontinue using it, she can regain fertility.
The unshortened process took nearly three decades. In 1990, Indian regulators tried Centchroman. Hindustan Latex Life Care, a public-sector undertaking (PSU) and Ahmedabad-based Torrent Pharmaceuticals were given licences to manufacture it with the name ‘Saheli’ (meaning sexuality friend). The World Health Organization (WHO) too tried the pill, giving it the technical name of ormeloxifene, and sold it worldwide as Novex-DS or Sevista.
Life and times
Born on 1 January 1925 in Lyallpur (Faisalabad) in present-day Pakistan, Nitya Anand grew up in a household surrounded by education. His father, Shri Bhai Balmukund, was a physics professor at a local college, while his mother served as the honorary principal of flipside institution for her work in training widows and other destitute women in handicrafts.
Besides social work, his parents were urgently involved in the self-rule struggle. Without earning his bachelor’s stratum in Lahore, he left for Delhi to well-constructed his MSc in chemistry from the once prestigious St Stephen’s College, pursuit which he left for Mumbai to do his research work in organic chemistry at the University Department of Chemical Technology (UDCT), Mumbai.
Earning his PhD in 1948 under the mentorship of Prof K Venkataraman, who incidentally moreover christened him ‘Nitya Anand’ from ‘Nityanand’, he moreover went on to obtain flipside PhD from St John’s College, Cambridge University under Prof Alexander (later Lord) Todd.
In an interview with Sansad TV, Dr Nitya Anand said, “We wanted to squint at the recent developments in biological sciences. I was very much interested in biological sciences right from the beginning. And professor Todd, who became a Nobel laureate and Lord Todd [later on], was one of the upcoming scientists in the field of chemical biology…That [stint] prepared me very well for what I was going to work on drug discovery research later.”
Amid all these wonk achievements, his family had to withstand the brunt of Partition. By 1947, his father had just retired and decided to stay in Pakistan. “He was tightly involved in social work. So, he decided to stay when in Pakistan considering there’d be lots of people who need his help [including] the Hindu families or plane other Muslim families…So he decided that they will stay when in Lyallpur. But conditions became difficult for people to stay when although Lyallpur was still pretty quiet till the end of August 1947,” he said on Sansad TV.
“But then the conditions started getting worse. I was in [a] panic. I was in Bombay and I knew increasingly well-nigh what was happening virtually me than they in Pakistan did. So, I decided that we must bring them out now and coming through other channels was difficult. Luckily, I had a very tropical friend who was working with Tata Airlines. His family was moreover in Lyallpur. So, I decided to take a plane, flew to Lyallpur and brought them out,” widow Dr Nitya Anand.
Upon landing in Lyallpur, his family had to vacate the house they had resided in for 50 years in just 2 hours and left everything behind. Undoubtedly, there was a mismatch of emotions. Without all, India was rhadamanthine an self-sustaining country without years of struggle.
“I still remember when the plane crossed the Wagah border, my father and mother heard the pilot say that ‘we have crossed into the India border’. They didn’t think well-nigh what they had left behind, but [that] ‘oh now we are in self-sustaining India’ and that is the kind of unconfined feeling which all three of us had…That’s a kind of unconfined feeling in an self-sustaining India,” he recalled.
After he returned to India in late 1950 pursuit his second PhD in the United Kingdom, and a short stint at Delhi University, he joined the Medicinal Chemistry Division of the newly inaugurated Central Drug Research Institute in March 1951.
In a tribute to him, Dr AK Saxena and Dr CM Gupta, senior officer bearers at CDRI, wrote, “Dr Anand started his research work at CDRI with the diamond and synthesis of sulphones and sulphonamides for leprosy. In this pioneering work, he made full use of the understanding of crucial factors in drug diamond such as transport wideness membranes, the biology of the parasite and pathology of the disease through a multidisciplinary approach.”
Dr Anand never stopped learning. To strengthen his skills remoter in drug research, he plane undertook post-doctoral training under a Rockefeller Foundation Fellowship in 1958 with professor Bernard D Davis at Harvard Medical School. And he never stopped contributing.
Throughout his career, he published increasingly than 400 research papers, received increasingly than 130 national and international patents and plane authored two books.
Wished Dr Nitya Anand, Former Director CDRI & doyen of Indian pharma on his 96th birthday and received his blessings as always. He is a powerhouse for all the scientists and energises us just by his presence.#HappyNewYear2021 and weightier wishes for a wonderful decade ahead. pic.twitter.com/XliKUthPVD

“An important outcome of Dr Anand’s scientific contribution was the megacosm of trained medicinal chemists. He has supervised well-nigh 90 students for their PhD degrees, the last one in June 2003, and many post-docs. Many of these now occupy senior research positions in R&D Labs of Academia and the Pharmaceutical Industry,” wrote Dr Saxena and Dr Gupta.
Until his retirement as director of CDRI in 1984, Dr Anand played a pivotal role in turning the institution into a globally-recognised centre for drug discovery and development, “especially for tropical diseases (malaria, filaria), contraception and drugs from medicinal plants, areas of special national relevance.”
He moreover well-considered the Government of India on formulating drug policy for nearly four decades while moreover consulting for other scientific institutions.
In 2012, he was awarded the Padma Shri for his contributions. An institution and nation builder, he should receive greater recognition for his hair-trigger contributions to Indian health and science.
