Are the combined genotypes and haplotypes of VDR gene polymorphisms () associated with PCOS susceptibility and metabolic features of the disease? We performed a case-control study, including 46 women with PCOS and 48 controls. Genotypes of VDR genes were determined using the PCR-RFLP (restriction fragment length polymorphism) method. In all women, the waist circumference, parameters of lipid and glucose metabolism were evaluated. PCOS group presented higher waist circumference and visceral adiposity index (VAI) levels compared to controls. Total cholesterol, LDL-C and triglycerides had higher values in PCOS women. VDR- C/C (F/F) genotype had significantly higher odds of PCOS (adjusted OR = 6.27, 95% CI: 1.53-25.65). VDR- was associated with susceptibility to PCOS in the dominant model, the variant genotype (A/C-A/A) (A/a- a/a) had higher odds of PCOS than the wild genotype C/C (A/A) (adjusted OR = 3.15, 95% CI: 1.07-9.32). Haplotype analysis revealed that T-C- T (f-A-T) haplotype was statistically associated with lower odds of PCOS (adjusted OR = 0.10, 95% CI: 0.01-0.95). PCOS women with VDR-Fokl T/T (f/f) genotype had lower fasting glucose and higher VAI levels compared to C/T (Ff) or C/C (F/F) genotype. The present findings suggest the association between and polymorphisms and PCOS susceptibility. Moreover, T/T (f/f) genotype of VDR- could be a marker of decreased fasting glucose in PCOS. polymorphism did not reveal a relationship with PCOS susceptibility in our study population.

This is a commentary to a paper recently published in RBMOnline by Macklon and De Vos, in which they argue for a discontinuation of ovarian tissue freezing for fertility preservation in women with breast cancer. Instead, they suggest the use of oocyte vitrification following ovarian stimulation as the preferred method of fertility preservation. This commentary presents nine separate arguments that should be considered in the context of ovarian tissue freezing and fertility preservation in girls and women. Collectively, the authors support ovarian tissue freezing going forward and suggest continuing this procedure for fertility preservation in women with breast cancer. Ovarian tissue freezing represents several advantages for patients and provides them with more options following treatment compared with oocyte vitrification.
本文是对 Macklon 和 De Vos 最近发表在《RBMOnline》上的一篇论文的评论,他们在文中主张停止将卵巢组织冷冻用于乳腺癌妇女的生育力保存。相反,他们建议将卵巢刺激后的卵母细胞玻璃化作为生育力保存的首选方法。本评论提出了九个不同的论点,这些论点应在女孩和妇女卵巢组织冷冻和生育力保存的背景下加以考虑。总之,作者支持继续进行卵巢组织冷冻,并建议乳腺癌妇女继续采用这种方法保留生育力。与卵母细胞玻璃化相比,卵巢组织冷冻为患者带来了多项优势,并为她们在治疗后提供了更多选择。

Although single women and lesbian couples are given access to donor spermatozoa, all kinds of restrictions limit their actual use of donor insemination. These restrictions are frequently justified by the increase in safety (lowering the genetic risk) or well-being of donor-conceived persons. However, these restrictions directly result in stratified reproduction in which only the rich (those with the necessary financial means) and the straight (those who conform to dominant views of parenthood) are allowed to reproduce.

Trophectoderm-based preimplantation genetic testing for aneuploidies (PGT-A) is used worldwide as a means of selecting embryos with high potential for achieving a live birth. However, trophectoderm analysis may be impaired through embryonic mosaicism, leading to genetically healthy embryos being falsely discarded, and thus even reducing cumulative live birth rates. Polar body biopsy, a technique applied since the early days of preimplantation testing, has been abandoned by most IVF centres. In comparison to trophectoderm analysis, however, polar body biopsy might even have certain advantages over trophectoderm PGT-A. This Countercurrent contribution discusses the newest clinical evidence, as well as ethical and cost-efficiency considerations, and argue that polar body analysis should be reconsidered.

Research question
Are bisphenols released from disposable devices used in assisted reproductive technology (ART) procedures, and do they accumulate when several disposable devices are used sequentially under routine conditions?
Design
A comprehensive assessment of 19 individual disposable devices (31 assessments) and nine combinations of disposable devices replicating the main steps in an ART procedure was undertaken. The extraction of bisphenols followed routine-use conditions (temperature and duration). The concentrations of 10 bisphenols were determined using online solid-phase extraction/liquid chromatography/mass spectrometry methodology.
Results
Bisphenol S (BPS) was quantified consistently from 100-mm culture dishes (32 ± 20 pg) and from high security sperm straws (3 ± 1 pg). Also, BPS and bisphenol A (BPA) were quantified consistently from spermicide-free condoms (95 ± 78 and 83 ± 49 pg, respectively). No other bisphenols were detected in disposable devices when tested individually. When disposable devices were used in combination, both BPA and BPS were detected consistently in combinations of 13 disposable devices mimicking sperm collection in a condom and its preparation (46 ± 16 and 43 ± 32 pg, respectively). BPS was quantified consistently in combinations of 14 disposable devices mimicking sperm collection, its preparation and freezing (10 ± 4 pg), and in combinations of 17 disposable devices mimicking oocyte retrieval (37 ± 22 pg).
Conclusions
BPA and BPS are released in small quantities from some disposable devices used in routine conditions during ART procedures, but do not appear to accumulate when these disposable devices are used in combination.

Is there an association between the ‘October 7th’ 2023 events and IVF outcomes in Israel?
Design
in this retrospective cohort study the study group was women treated during the 4 weeks after ‘October 7th’, compared with a matched control group treated between 1 January 2021 and 6 October 2023. Each study group participant was matched with three separate control subjects of the same female age at oocyte retrieval, with a matching body mass index (BMI), IVF cycle number and ovarian reserve parameters.
Results
The study included 580 patients. The 145 women who underwent oocyte retrieval or frozen embryo transfer after 7 October 2023 were compared with 435 women treated before 7 October. The mean age of the study group was 35.6 ± 5.9 years, and the mean BMI 25.01 ± 5.60 kg/m2. Pregnancy rates per embryo transfer were similar between the groups (22.4% versus 30.5%, P = 0.28 in fresh cycles; 16.9% versus 27.1%, P = 0.12 in frozen embryo transfers). Among women who underwent oocyte retrieval there were no differences in the ovarian stimulation protocols (P = 0.95), number of oocytes retrieved (P = 0.16) or number of fertilized oocytes (P = 0.34). There was no difference in the rate of good-quality embryos between groups (P = 0.053). Among women who underwent frozen embryo transfers, during the study period more patients had natural cycles (52.5% versus 24%, P < 0.001), and there was no difference in maximal endometrial thickness before embryo transfer (P = 0.33).
Conclusions
It appears that there is no association between the ‘October 7’ events and IVF outcomes.
