"OBV occurs at an intersection between institutional violence and violence against women during pregnancy, childbirth and the postpartum period," she said.
A point that was nailed by most speakers at the event was the unfortunate mistreatment of pregnant women by nurses during delivery.
Indeed, who can forget the January 2017 hashtag #nursesfromhell, in which an unidentified group of nurses bragged over horrific ways they handle 'difficult' women going to the hospital to deliver?
In 2016 the Ministry of Health, National Nurses Association of Kenya, the Federation of Women Lawyers and the American NGO Population Council published data showing one in five women giving birth in local hospitals is humiliated, abused and asked for a bribe.
"Women are physically and verbally abused while in delivery wards. They are treated as if they don't know anything and should only take instructions from those attending to them. We don't talk about it yet it is wrong," Wamuchomba said.
While the behaviour of the ill-mannered nurses is noteworthy, Dr Kihara - who is also the President of the International Federation of Gynaecology and Obstetrics (FIGO) - added that OBV goes beyond healthcare providers mishandling patients.
She said: "A lot of OBV occurs because of the healthcare system - the doctor-to-patient ratio, the number of trained health personnel, the availability of properly equipped hospitals, financing for healthcare, availability of medicines, and so on - is not properly functioning."
Dr Kireki Omanwa, the president of the Kenya Obstetrical and Gynaecological Society (KOGS), spoke at the event: noting that OBV has led to loss of lives in some instances.
"When a woman is not able to deliver safely, because they can't access the best possible maternity care, this too is OBV. As Obstetricians and Gynaecologists, we are well too versed on the life-and-death struggles inside maternity rooms in Kenya; especially in public hospitals," Dr Omanwa said.
"Postpartum haemorrhage (PPH) is the number one killer of pregnant women in Kenya. This is because in many cases medics don't even have medicines, tools and equipment to use in treating PPH. All these things deny Kenyan women a dignified and assured maternity process; which ideally should be a happy process of bringing forth new life," Dr Omanwa added.
On her own experience, Wamuchomba says that the nurses should have known that a woman in active labour has the same feeling that one has when they need to relieve themselves.
"Why didn't they inform me that the feeling is the same as that of wanting to go to the toilet?" she asks, rhetorically.
The MP came across the term OBV while on an official trip to South Africa while speaking to staff at a Centre for Legal Studies, in a South African University.
"I took immediate and keen interest and learnt that when you deny a woman the right to see her baby in the incubator because she has not paid hospital fees, that's OBV. When you detain a mother who has given birth, because they can't afford treatment, that's OBV.
"It occurred to me that we go through these things but don't even recognise that we are indeed being abused: that our fundamental rights as women giving birth are being trampled on," she says.

Wamuchomba has prepared a motion seeking for parliament to order the development of a policy paper around OBV.
"The motion will allow us to debate in the house. If members agree that we need proper legislation and policy around OBV, then we shall go ahead and have it done."
The meeting, attended by representatives from Kenya Human Rights Commission (KCHR), Amref, KOGS, KEWOPA, Members of Parliament, and OBV survivors, yielded ideas that Wamuchomba says would be important in developing laws and policies on OBV: "to make sure that it is criminalised and therefore punishable."
