Ectopic ovarian pregnancy after intracytoplasmic sperm injection with testicular spermatozoa - a case report

“…According to Marcus & Brinsden (1995), 4.5-6% of all cases of extrauterine pregnancy and 0.35% of all clinical pregnancies are ovarian pregnancies. Choi et al (2011) looked into 3081 cases of ectopic pregnancy and found that 49 were cases of ovarian pregnancy (1.59%), as similarly reported by Grimes et al (1983); Gaudoin et al (1996) and Raziel et al (2004).…”

Primary ovarian pregnancy: early diagnosis still a myth

Diagnostic surprises in early pregnancy: two case reports

“…Various hypothesis have been put forward like fertilization of ovum inside the ovary or implantation of fertilized ovum in ovary, PID, reverse migration of fertilized ovum, tubal diseases and thickened tunica albuginea, interference with release of ovum from ruptured follicles. [3][4][5] Additionally IVF and IUCD's are implicated to increase its incidence. 4 Treatment of almost all known ovarian ectopic pregnancies has been surgical.…”

“…[3][4][5] Additionally IVF and IUCD's are implicated to increase its incidence. 4 Treatment of almost all known ovarian ectopic pregnancies has been surgical. Although there are successful case reports with methotrexate management in hemodynamically stable and low HCG titre patients.…”
