You do not have permission to edit this page, for the following reasons:

This IP address has been blocked from editing Wikipedia.
This does not affect your ability to read Wikipedia pages.
Most people who see this message have done nothing wrong. Some kinds of blocks restrict editing from specific service providers or telecom companies in response to recent abuse or vandalism, and can sometimes affect other users who are unrelated to that abuse. Review the information below for assistance if you do not believe that you have done anything wrong.

The IP address or range 44.201.0.0/16 has been blocked (disabled) by ‪ST47‬ for the following reason(s):

The IP address that you are currently using has been blocked because it is believed to be a web host provider. To prevent abuse, web hosts may be blocked from editing Wikipedia.
You will not be able to edit Wikipedia using a web host provider because it hides your IP address, much like a proxy or VPN.
We recommend that you attempt to use another connection to edit. For example, if you use a proxy or VPN to connect to the internet, turn it off when editing Wikipedia. If you edit using a mobile connection, try using a Wi-Fi connection, and vice versa. If you are using a corporate internet connection, switch to a different Wi-Fi network. If you have a Wikipedia account, please log in.
If you do not have any other way to edit Wikipedia, you will need to request an IP block exemption.

How to appeal if you are confident that your connection does not use a web host's IP address:
If you are confident that you are not using a web host, you may appeal this block by adding the following text on your talk page: ((unblock|reason=Caught by a web host block but this host or IP is not a web host. My IP address is _______. Place any further information here. ~~~~)). You must fill in the blank with your IP address for this block to be investigated. Your IP address can be determined here. Alternatively, if you wish to keep your IP address private you can use the unblock ticket request system. There are several reasons you might be editing using the IP address of a web host (such as if you are using VPN software or a business network); please use this method of appeal only if you think your IP address is in fact not a web host.

Administrators: The IP block exemption user right should only be applied to allow users to edit using web host in exceptional circumstances, and they should usually be directed to the functionaries team via email. If you intend to give the IPBE user right, a CheckUser needs to take a look at the account. This can be requested most easily at SPI Quick Checkuser Requests. Unblocking an IP or IP range with this template is highly discouraged without at least contacting the blocking administrator.

This block will expire on 23:54, 31 July 2024.

Even when blocked, you will usually still be able to edit your user talk page, as well as email administrators and other editors.

For information on how to proceed, please read the FAQ for blocked users and the guideline on block appeals. The guide to appealing blocks may also be helpful.

As a young man, Ratnam began his career as a [[Pre-registration house officer|houseman]] (trainee medical officer) at the [[Singapore General Hospital]] in 1959. He also began teaching at the [[University of Singapore]] in 1963.

After obtaining his M.R.C.O.G (and later, the F.R.C.S.) in 1964 in England, he was appointed to the post of Professor and Head of the Department of Obstetrics and [[Gynaecology]] in [[Singapore]], a post which he held for 25 years.

In 1972, Ratnam's Obstetrics and Gynaecology department received the accolade as being one of "13 research centres in human reproduction in the world", recognition conferred by the [[World Health Organization]].

In 1970 he was made Chief Examiner and Director (1972) of Postgraduate Medical Studies at the [[National University of Singapore]]. He was a member of the editorial boards of several learned journals, including the International Journal of Obstetrics & Gynaecology, and International Journal of Prenatal and Perinatal Studies.

He also led conception of the first [[in-vitro fertilization]] process in Asia, in 1983. He tried out IVF experiments on [[rat]]s prior to his first, successful attempt on using IVF to conceive babies.

In 1987, he also pioneered the procedure of giving birth to a baby born from frozen [[embryo transfer]]. He was part of a team of clinicians and scientists which led to the world's first [[microinjection]] baby via human ampullary [[Cell culture|coculture]] in 1991.<ref>((cite book|title=The History of Obstetrics & Gynaecology in Singapore|url=https://books.google.com/books?id=s5GYGAAACAAJ|year=2003|publisher=Obstetrical & Gynaecological Society of Singapore|isbn=978-981-4045-68-1|pages=498–502))</ref>

Ratnam also contributed to gynaecology through research. He had credit to 378 research papers in the referred International Journals, 232 research papers in the referred local and regional journals, including nineteen non-referred journals.

His career as a research scientist and teacher continued at the National University of Singapore despite his official retirement in 1998, as [[Emeritus]] Professor of [[Gynaecology]] and [[Obstetrics]]. He was a world authority on sex change operations, developing new techniques for [[transsexualism]], [[embryo replacement]], in vitro and controlled fertilisation.

His work with transsexual patients was shown in a documentary called "Shocking Asia".  In this documentary, he was shown talking about his background with transsexual patients.  He talked about how he first got involved with "the problem" (referring to the patient's penis) and how he used [[cadaver]]s to come up with his technique of sexual reassignment surgery.  It also shows his assistant, Dr Lim, taking some final pictures of a patient before her surgery.

==Personal life==
Professor Ratnam suffered a stroke in December 1999. He developed heart complications and passed away from pneumonia at 6.55 p.m. on 6 August 2001 in the [[National University Hospital]] of [[Singapore]] at the age of 73.<ref name="auto"/>

Many of his former students are now members in the O&G field including the current head of department at the National University Hospital, Dr P. C. Wong. He  was a [[Hindu]] during his lifetime. He had two children; one son and one daughter. A centre at [[Camden Medical Centre]] was named after him, SSR International (Private International). The centre is currently run by his nephew C. Anandakumar.
