Is in vitro maturation of oocytes retrieved ex vivo from ovarian tissue an effective fertility preservation technique in the presence of organic ovarian cysts?

OBJECTIVE(S): In vitro maturation (IVM) of oocytes retrieved ex vivo from ovarian tissue (OTO-IVM) could be an additional source of mature oocytes with the potential to optimise medical fertility preservation (FP) after oophorectomy. It is often undertaken at the same time as the ovarian tissue cryopreservation (OTC). In the presence of an organic ovarian cyst, OTO-IVM could prove to be the only technique available to permit FP since ovarian stimulation, transvaginal ovarian needle puncture or future ovarian tissue graft are contraindicated. However, the presence of an organic cyst could alter follicular growth and the number of retrievd oocytes. Our study aims to assess the efficiency of OTO-IVM in such situations. STUDY DESIGN: Retrospective, observational study involving 20 female patients with FP by OTO-IVM between May 2017 and November 2021 at the University Hospital of Toulouse. Oocytes retrieved "ex vivo" were transferred to an IVM medium with HP-hMG, LH and HSA and then vitrified after 24 to 48 h of IVM. Data analysis was performed on the total population and comparatively between patients who had or did not have an organic ovarian cyst. RESULTS: The indications included 15 oncologic and 5 non-oncologic indications. Ten had an organic ovarian cyst on the retrieved ovary. The number of retrieved oocytes was 17.4+/-12.0 in the absence of cyst vs 4.1+/-6.3 in the presence (p = 0.003). The number of vitrified mature oocytes was 5.8+/-5.3 in the absence vs 1.1+/-2.2 (median = 0) in the presence of a cyst (p = 0.03). Ninety percent of the patients with an organic cyst had less than two vitrified mature oocytes. The mean maturation rate was 34%, not significantly different between the two groups. We found a correlation between serum AMH level and the number of mature oocytes: ρ:0.47 CI95 = [0.02; 0.76]; p = 0.04. CONCLUSION(S): OTO-IVM is an additional source of mature oocytes to optimise FP after oophorectomy. However, in the presence of an organic ovarian cyst on the retrieved ovary, the exocrine, paracrine and endocrine functions of the ovary are impaired. As such, the number of immature oocytes obtained is highly impacted and appears to be insufficient to be able to propose systematically this technique in such situations.

Fertility and sexuality of women with inflammatory arthritis.

OBJECTIVE: This study aimed to evaluate the impact of the four main types of inflammatory arthritis (rheumatoid arthritis (RA), ankylosing spondylitis (AS), psoriatic arthritis (PA), juvenile chronic arthritis (JCA)) on female fertility. DESIGN: We performed a monocentric observational study, which took place in the Reproductive Medicine Department and the Rheumatology Department of the Toulouse University Hospital. An anonymous questionnaire was sent to patients aged 18-50 with RA, AS, PA or JCA who were diagnosed before the age of 40 and who consented to participate in the study. A section of the questionnaire was completed using the medical file of each patient. RESULTS: Of the 521 eligible patients, 202 (39 %) answered the questionnaire. Before being diagnosed with a rheumatic disease, 87 % of patients with a desire for pregnancy had a spontaneously obtained live birth, compared to 75 % after (P < 0.05). However, this decrease only concerned RA (90 % before diagnosis vs 68 % after; P < 0.05). This difference was due to a lower rate of pregnancies achieved, but the number of miscarriages did not increase. Moreover, for patients who managed to conceive, the time required for conception did not increase, regardless of the type of rheumatic disease they had. Two thirds of patients reported a decrease in the frequency of sexual intercourse after diagnosis, mainly (75 %) because of the pain relating to the disease. CONCLUSION: Our study shows a trend of decreased fertility in patients with RA, perhaps due to sexual problems, while no impact of AS and PA on the ability to conceive was found. This impact on fertility didn't seem to be related to the decrease of sexuality. Multidisciplinary care including treatment from a rheumatologist, gynecologist and sexologist would appear essential in order to provide RA patients with the necessary information concerning their fertility, answer their questions about pregnancy and thus optimize their care.
