Luteectomy in early pregnancy. A report of three cases.

The exact day in early pregnancy when the corpus luteum could be dispensed with without deleterious effects on the pregnancy has been a matter of some dispute. It seems that there is a difference regarding the prognosis of the pregnancy if luteectomy or oophorectomy is performed where the corpus luteum alone could be dispensed with somewhat earlier. Three cases are presented. In case one luteectomy was performed at the end of week six or day 42 according to Naegele's rule. Plasma progesterone values decreased initially but increased steadily thereafter. No abortion occurred. Patient No. two was oophorectomized unilaterally at day 53 on the side where the corpus luteum was situated. She aborted three days later. Patient No. three was oophorectomized in the same was as patient No. two at day 49 and treated with Progesterone substitution thereafter. No signs of threatening abortion could be seen.
