Her 10-semester study was interrupted by a typhus infection and later for two years by the Russo-Japanese War, during which time she worked at a military hospital for women and children in Moscow.

In December that year, she married an Austrian physician and naval officer Friederik Groyer who had a medical practice in a Klimkovice spa, and started as his assistant.

[1][3] Later records show that Jenko Groyer worked as an unpaid physician at a state hospital in Ljubljana, with special permission of the executive government, while her husband moved to Matulji.

Her patients there were exclusively women, some influential residents there electing to support her struggle for professional recognition, among those the painter Lea von Littrow.

Jenko Groyer returned to Ljubljana and was entrusted vaccination against smallpox and later general medical service in the Grosuplje district.

After the war, she again faced bureaucratic hurdles in the newly formed Kingdom of Serbs, Croats and Slovenes to have her degree recognized, and had to take extra exams at the University of Zagreb.
