About this study
The investigators retrospectively analysed the complication rate of ultrasound guided transvaginal oocyte retrieval (TVOR) from all the procedures performed between 1996 and October 2016 in a tertiary level university based fertility clinic.
Read the detailed description
Ultrasound guided transvaginal oocyte retrieval (TVOR) is nowadays gold standard techniques to collect oocyte after ovulation induction in Assisted Reproductive techniques (ART). It is a very safe technique with infectious complications of any kind occurring in just 1% (Bennett et al.) of all procedures, vaginal bleeding in 0 to 1.3% of the procedures (Ludwig et al., Bodri et al., Aragona et al.) and vascular, gastrointestinal and genitourinary (Grynberg et al. and Catanzarite and al.), injuries being extremely rare (Bennett et al.). Case reports account also for rarer complications such as ovarian abscess formation (Kelada \& Ghan and Sharp et al.) pseudoanerysm formation (Bozdag et al. and Jayakrishnan et al.), uroretroperitoneum (Fiori et al.).
The rational of thestudy is to provide the percentages of complication from TVOR of the Fertility Center of Humanitas Research Hospital, also considering the development in time of technologies and techniques in Assisted Reproduction. Another rational is inquire whether there is any risk factor for such complications in order to try to prevent them in future procedures. The investigators performed a retrospective observational study including all the transvaginal oocyte retrieval procedures performed between 1996 and October 2016.
The data have been collected from the Humanitas Fertility Center' Department database (ART.it). Because of the retrospective nature of this study, a specific informed consent was not necessary.

Questions about this trial
What is this clinical trial studying?
An observational study of In Vitro Fertilization, run by Istituto Clinico Humanitas.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 21 Mar 2019. Status can change between updates, so confirm with the study contact before making plans.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
complications rate (time frame: 20 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT03282279, which also lists 12 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Mar 2019.
