Foretog som den første i Verden ægudtagning ved hjælp af ultralydscanning. Det var i 1980. Før den tid blev æggene taget ud ved laparoskopi (kikkertoperation)

 

Ved de første ægudtagninger med ultralyd, blev der scannet og stukket gennem huden på maven.

tog æggene ud ved den behandling, der førte til Danmarks første reagensglasbarn, som blev født i 1983. Det var den metode, som blev brugt ved den første fødsel på verdensplans efter ægudtagning med ultralyd. 

var den første i Danmark til at følge æg-blærenes vækst med ultralydscanning og den første til at følge livmoderslimhindens vækst gennem menstruationscyklus

 

Livmoderslimhinden (mellem pilene) som den ser ud ved ultralydsscanning før ægløsning.

 

Follikel (ægblære) lige før ægløsning. Ses mellem pilene og er 19 mm. i tværmål.

har udviklet en metode til screening for testikelkræftforstadier

 

Ultralydsprint af normal tekstikel.

 

Ultralydsprint af "risiko tekstikel" . Den er mindre, mørkere og med hvide prikker, sammenlignet med den normale.



har forsket i scanning af bitestiklen

udviklede en befrugtningskapsel, til at lægge op i livmoderen efter at æg og sædceller var deponeret i den. Metoden blev afprøvet, men resulterede ikke i graviditet

 

2 befrugtningskapsler med forskellig vægtykkelse; begge er 1,5 cm. lange.



forsøgte som den første i Verden at føre æggene tilbage ved punktur gennem maven (Australien 1986)

har taget medicinsk doktorgrad i IVF behandling

 





Forsker akuelt i ultralydsscanning af brystet og i samarbejde med Århus og Herlev Universitetshospitaler i undersøgelse for HPV i brystkræft væv.
