Unilateral congenital ovarian and partial tubal absence: Report of four cases with review of the literature

Ectopic pregnancy after IVF in a patient with unilateral agenesis of the fallopian tube and ovary and with endometriosis: search of the literature for these associations

“…Although it is known that the incidence of ectopic pregnancy is higher in pregnancies after IVF (from 2.1 % to 8.6 %) [14,15], the incidence in cases of unilateral absence of ovary and tube it is not known. A couple of interesting, but unproven, hypotheses could explain the ectopic pregnancy of this case, either as associated with the presence of endometriosis causing abnormal tubal ciliary function [16,17], or the agenesis of one fallopian tube could be correlated with the inefficiency of the other as well [2,4,12,18].…”

A Case of Congenital Unilateral Partial Absence of Fallopian Tube

“…Recently, two similar cases of ovarian and tubal absence due to adnexal torsion were reported 11,15) , one case of unilateral ovarian absence with a twisted fallopian tube 11) and one case of a unilateral fallopian tube defect with twisted adnexa (ovary and infundibulopelvic ligaments) 15) . As for the frequencies of these conditions, Uckuyu et al reported three cases of partial tubal absence, and the incidence of three in 2,550 (one in 850) females underwent laparoscopy or laparotomy at their institute 16) . Our comprehensive literature research, including 19 cases reported by Nawroth, showed that only three out of 30 patients with partial absence of the fallopian tube were complicated with ipsilateral ovarian absence (one case with absence of the proximal portion and two cases with absence of the distal portion of the fallopian tube) 3,8,9,15−21) .…”

“…However, the absence of any other anatomical structures such as uterine or renal abnormalities would suggest that torsion or a vascular accident, rather than a developmental anomaly, is the likely cause 16) . The unilateral absence of a fallopian tube, in conjunction with a normal contralateral tube and uterus, may have less influence on infertility.…”

Unilateral ovarian hypoplasia—A report of two cases

“…Several authors have reported congenital ovarian agenesis in the setting of normal or abnormal fallopian tube development [1][2][3][13][14][15][16][17][18]. However, the number of reports is small and knowledge about these developmental anomalies is limited.…”

“…However, the number of reports is small and knowledge about these developmental anomalies is limited. There are few data in the literature on unilateral ovarian hypoplasia [12,15].…”
