Fertility preservation in patients undergoing gonadotoxic treatments: a Canadian Fertility and Andrology Society clinical practice guideline

The management of young patients with cancer presents several unique challenges. In general, these patients are ill prepared for the diagnosis and the impact on their fertility. With the improved survival for all tumour types and stages, the need for adequate fertility counselling and a multidisciplinary approach in the reproductive care of these patients is paramount. Recent advances in cryopreservation techniques allow for the banking of spermatozoa, oocytes, embryos and ovarian tissue without compromising survival. This Canadian Fertility and Andrology Society (CFAS) guideline outlines the current understanding of social and medical issues associated with oncofertility, and the medical and surgical technologies available to optimize future fertility.

[What issues, changes and adaptations for French ART centers in the context of the new bioethics law?]

OBJECTIVE

This review intends to introduce the changes of the new Bioethics law in the reproductive field and its application in French ART centers.

MATERIAL AND METHODS

The review details the main provisions of the Bioethics Law of August 2nd 2021 as well as the three decrees published since: the first one on September 29th 2021, which specifies in particular the age conditions to benefit from ART and self-preservation of one's gametes; another decree on December 31st, 2021, to set the terms and conditions for gamete self-preservation activities for non-medical reasons and the last decree on April 14th 2022, relating to the allocation of donated gametes and embryo donation.

RESULTS

Since the law of August 2nd, 2021, access conditions to assisted reproductive technology (ART) have evolved in France. Previously based on pathological infertility or the risk of transmission of a serious disease, ART is now intended to respond to the parental project of a couple formed by a man and a woman, two women or an unmarried woman. With the widening of access conditions, the use of gamete donation will likely increase. The upcoming raise of children born from gamete donation has led the legislator to question their right to access their origin. From September 1st 2022, adults born from gamete donation will be able to request a special administrative authority in order to access the donor's non identifying data (age, physical characteristics, family and professional situation, motivation for the donation…) and/or the donor's identity. Moreover, the new bioethics law opens up the possibility of autologous gamete cryopreservation without medical reasons, under specific age conditions, in order to carry out an assisted reproduction technique later. If gametes are not used, autologous gamete preservation could also allow an increase in gamete donation. However, the modification of gamete donation conditions could suggest a short term decrease in donors' number. Finally, the new bioethics law further opens up research on human embryos and embryonic stem cells.

CONCLUSION

The arrangements introduced by the Bioethics Law promulgated on August 2nd, 2021 represent a major revolution in the field of Reproductive Medicine and are expected to transform the practices of reproductive biology centers and CECOS in France.

Oocyte Retrieval during Laparoscopic Vaginoplasty to Reduce Invasiveness in the Treatment of Mayer-Rokitansky-Küster-Hauser Syndrome

STUDY OBJECTIVE

To evaluate the treatment of patients with Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome with a combination of oocyte retrieval and surgical vaginoplasty in a single laparoscopic procedure.

DESIGN

A case series.

SETTING

The study was conducted at 2 tertiary referral facilities for MRKH syndrome in Milan, Italy, between July 2017 and September 2018.

PATIENTS

Eleven patients presented with MRKH and required surgical vaginoplasty while expressing a desire for future fertility.

INTERVENTIONS

Two experienced surgeons and an expert in assisted reproductive technology performed concomitant vaginoplasty according to the modified technique of Davydov and laparoscopic oocyte retrieval for gamete cryopreservation.

MEASUREMENTS AND MAIN RESULTS

Before the procedure, patients underwent extensive counseling and gave written consent. At the start of surgery, 10.4 ± 4.4 (mean ± standard deviation [SD]) oocytes were retrieved laparoscopically, and 8.8 ± 3.1 (SD) mean mature oocytes were cryopreserved. After oocyte retrieval, the steps of the modified Davydov technique were followed. The total operative time was 116 ± 16 minutes (mean ± SD), and no intraoperative/postoperative complications were observed.

CONCLUSION

This is the first report of combined oocyte retrieval and vaginoplasty for patients with MRKH syndrome. The approach was found to be feasible in patients with a desire for future fertility. It is our belief that physicians treating patients with MRKH should refer patients to centers with expertise in both vaginoplasty and assisted reproductive technology.

Fertility Preservation for Transgender Adolescents

PURPOSE

To describe fertility preservation (FP) utilization by transgender adolescents within a pediatric gender clinic between July 2013 and July 2016.

METHODS

A retrospective chart review was conducted to abstract demographic and clinical information among adolescents initiating gender-affirming hormones, including patient age at initial FP consultation, birth-assigned sex, race/ethnicity, and outcome of FP consultation.

RESULTS

In our sample of 105 transgender adolescents, a total of 13 (seven transgender men and six transgender women) between the age of 14.2 and 20.6 years were seen in formal consultation for FP before initiating hormones. Of these adolescents, four completed sperm cryopreservation and one completed oocyte cryopreservation.

CONCLUSIONS

Rates of FP utilization among transgender youth were low, which is consistent with a recently published report of FP utilization among transgender youth at another pediatric institution. Identified barriers to FP in our sample included cost, invasiveness of procedures, and desire not to delay medical transition.
