Anti-abortion activists camped out near his hospital, which an NHS doctor confronted, claimed that women seeking medical care were being "bullied" by them.
This week, outside Glasgow's Royal Hospital for Children, Dr. Greg Irwin dealt with protesters during a 40-day "vigil.".
The organization is linked to the US anti-abortion group 40 Days of Life.
Scotland is expected to pass a law allowing "buffer zones" to prevent protesters from congregating close to medical facilities.
After leaving his hospital to address the group on Wednesday, Dr. Irwin, a paediatric radiologist, was featured on the front pages of Scottish newspapers.
He explained: "I tried to explain the significance of the protest to a new protester, a middle-aged man I hadn't seen before.
"I told him it was upsetting patients and staff, and I asked him to consider whether this was what he should be doing.
"Hopefully, he will realize that I was sincere when I asked him not to bring up the protest again and shook his hand at the conclusion of our one-sided conversation. ".
The protesters initially started outside the structure, at Glasgow's Queen Elizabeth University Hospital. Prior to six or seven years.
When Dr. Irwin challenged the group in the past, he claimed he always got the same response that they were "holding a vigil" or "trying to help women.".
He continued, "The main impact of the protests is to upset staff members and patients emotionally.
"One in three women will use abortion healthcare, so judgmental demonstrations outside the hospital have a real and unfavorable impact, especially on these staff members.
"However, they also have an impact on other staff members, including myself, who find it upsetting to learn that there are protesters outside the hospital intimidating patients as they enter.
"This has bothered me throughout the protest period because it is such an unbelievable act of cruelty and unkindness. ".
A Supreme Court decision in December made it possible for Scotland to enact a new law creating safe access zones outside abortion clinics.
According to the court, the legislation creating these zones in Northern Ireland did not "disproportionately interfere" with the rights of protesters.
Scottish legislation would be approved as soon as possible, according to then-Minister of Women's Health Maree Todd.
The first region of the UK to adopt legislation governing buffer zones around abortion clinics is Northern Ireland.
The Abortion Services Safe Access Zones (Scotland) Bill, sponsored by Scottish Green MSP Gillian Mackay, has been gaining support from the Scottish government.
In order to provide women with access to services without fear, harassment, or intimidation, it would be possible to establish 150m (492ft) zones outside of health facilities.
Previously, a US anti-abortion group declared that it would support the legal challenge.
The bill should be "the most fairly balanced it can be," according to the faith-based legal advocacy group ADF UK, which opposes buffer zones.
Similar proposals for safe access zones in England and Wales were supported by MPs in October, but they are still pending in Parliament.
International vigils are organized by the US-based campaign organization 40 Days for Life. .
One of 12 in the UK, the protest in Glasgow is set to end on April 2.
