MIND THE GAP - ISTHMOCELES AND INFERTILITY

Morris JM, Romanski PA, Harris BS. Mind the Gap – Isthmoceles and Infertility. Fertil Steril. 2022 Dec 7:S0015-0282(22)02093-3. doi: 10.1016/j.fertnstert.2022.12.006. Epub ahead of print. PMID: 36496081.

Prior studies have determined that a large isthmocele, an indentation of the myometrium at the site of incision from poor healing of the uterine tissue following Cesarean delivery, produces multiple unfavorable outcomes related to embryo implantation and development. This study enrolled women with unexplained infertility and prior Cesarean delivery resulting in a large isthmocele (residual overlying myometrial thickness of < 3 mm or residual myometrial thickness of <50% of adjacent myometrial tissue) and the primary outcome was endometrial thickness in the presence or absence of intrauterine fluid. Results from this study suggest that presence of an intrauterine fibroid had no significant effect on endometrial thickness (p=0.25), and that there exists a relationship between intrauterine fluid and a slightly longer duration of infertility (24 vs. 27 months; p=0.02).

EFFECT OF TIMING BY ENDOMETRIAL RECEPTIVITY TESTING VS STANDARD TIMING OF FROZEN EMBRYO TRANSFER ON LIVE BIRTH IN PATIENTS UNDERGOING IN VITRO FERTILIZATION: A RANDOMIZED CLINICAL TRIAL

Doyle N, Jahandideh S, Hill MJ, Widra EA, Levy M, Devine K. Effect of Timing by Endometrial Receptivity Testing vs Standard Timing of Frozen Embryo Transfer on Live Birth in Patients Undergoing In Vitro Fertilization: A Randomized Clinical Trial. JAMA. 2022 Dec 6;328(21):2117-2125. doi: 10.1001/jama.2022.20438. PMID: 36472596; PMCID: PMC9856480.

Frozen embryo transfers have gained popularity in recent years, and in 2020, 75% of fertility treatment cycles involved embryo cryopreservation. This randomized clinical trial was initiated to determine if the use of endometrial receptivity assay (ERA) to time frozen euploid blastocyst transfer increases the probability of live birth. Study participants were planning to undergo IVF, PGT-A testing, and frozen embryo transfer. Participants were aged 30 to 40 years old at the time of egg retrieval and likely to produce at least 1 euploid blastocyst. 767 patients were randomized to one of two study arms: use of ERA to time frozen embryo transfer, or standard timing for embryo transfer. Results from the study indicate that live birth rate is not improved with the use of ERA testing, compared to standard timing of frozen embryo transfer (58.5% vs. 61.9%, respectively; difference, -3.4% [95% CI, -10.3% to 3.5%]; rate ratio [RR], 0.95 [95% CI, 0.79 to 1.13]; P = 0.38). Similarly, clinical pregnancy rate was not improved with the use of ERA testing, compared to the control group (68.8% vs. 72.8%, respectively; difference, −4.0% [95% CI, −10.4% to 2.4%]; RR, 0.94 [95% CI, 0.80 to 1.12]; P = .25).

FSH: THE GOLDILOCKS HORMONE, TOO LITTLE, TOO MUCH, JUST RIGHT

Santoro N. FSH: The Goldilocks Hormone, Too Little, Too Much, Just Right. Fertil Steril. 2022 Dec 5:S0015-0282(22)02058-1. doi: 10.1016/j.fertnstert.2022.12.003. Epub ahead of print. PMID: 36481419.

In this Views and Reviews, Dr. Nanette Santoro discusses the complexities related to FSH dosing during IVF. Recent research has supported the use of higher dosages of FSH during ovarian stimulation, but these high doses of FSH may affect tissues outside the desired gonadal targets. The current literature surrounding the topic suggests that there is still much to learn regarding FSH and ovarian stimulation.

MEETING THE CHALLENGE OF UNCLAIMED CRYOPRESERVED EMBRYOS

Go KJ, Romanski PA, Bortoletto P, Patel JC, Srouji SS, Ginsburg ES. Meeting the challenge of unclaimed cryopreserved embryos. Fertil Steril. 2022 Dec 4:S0015-0282(22)01744-7. doi: 10.1016/j.fertnstert.2022.09.323. Epub ahead of print. PMID: 36476953.

As the number of IVF treatment cycles with supernumerary embryos and freeze-all cycles continues to increase across the United States, many practices are faced with the storage and responsibility of a growing number of unclaimed embryos. Authors examine the importance of thorough and inclusive informed consent for embryo cryopreservation, discuss patients’ attitudes and decisions while they have embryos in storage, practice obligations, and alternative dispositions options for patients rather than embryo discard in the laboratory.

MENOPAUSE HORMONE THERAPY AND COMPLEMENTARY ALTERNATIVE MEDICINE, QUALITY OF LIFE, AND RACIAL/ETHNIC DIFFERENCES: THE STUDY OF WOMEN'S HEALTH ACROSS THE NATION (SWAN)

Christmas M, Janssen I, Joffe H, Upchurch D, Santoro N, Kravitz HM. Menopause hormone therapy and complementary alternative medicine, quality of life, and racial/ethnic differences: the Study of Women’s Health Across the Nation (SWAN). Menopause. 2022 Dec 1;29(12):1357-1364. doi: 10.1097/GME.0000000000002087. Epub 2022 Oct 16. PMID: 36256923.

A SWAN survey was completed by 2,514 midlife women with vasomotor and/or genitourinary symptoms of menopause from seven sites across the United States to investigate a relationship between hormone therapy or complementary alternative medicine and self-reported quality of life, and if race/ethnicity influences hormone therapy and complementary alternative medicine’s relationship with quality of life. The major findings from the study include: across all ethnicities/races, neither contemporary alternative medicine nor hormone therapy were associated with self-reported quality of life; white women using hormone therapy reported higher quality of life; Black and Hispanic women reported the lowest use of hormone therapy but more frequent menopausal symptoms, compared to other ethnicities and races.
