Associations between follicular fluid trace elements and ovarian response during in vitro fertilization.

Introduction: Exposure to trace elements has been associated with ovarian response in experimental studies. We conducted a hypothesis-generating study of associations between ovarian follicular fluid (FF) trace elements and measures of ovarian response among women using in vitro fertilization (IVF).

Methods: We collected ovarian FF specimens from 56 women.

Decision regret, and other mental health outcomes, following fertility preservation in the transgender individual compared to the cisgender woman.

Purpose: This study aimed to (1) determine differences in depression, anxiety, body image, quality-of-life (QOL), and decision regret scale (DRS) scores in transgender individuals undergoing fertility preservation (FP) compared to those who decline and (2) determine if DRS score following FP varies between transgender individuals and cisgender women.

Methods: Sixteen transgender birth-assigned (BA) females and 13 BA males, undergoing FP consultation at an academic center between January 2016 and November 2019, were compared to each other and cisgender cohorts with pre-existing data: 201 women undergoing elective oocyte cryopreservation (EOC) between 2012 and 2016 and 44 women with cancer undergoing FP between 1993 and 2007. Outcomes included demographics; validated scales for depression, anxiety, body image, QOL (see below) in the trans cohort; DRS score in all three cohorts.

Müllerian Duct Anomalies: Role in Fertility and Pregnancy.

Müllerian duct anomalies (MDAs) have important implications for the reproductive health of female patients. In patients with both infertility and recurrent pregnancy loss, the incidence of MDAs is as high as 25%. Congenital uterine anomalies are often only part of a complex set of congenital anomalies involving the cervix, vagina, and urinary tract.

Toxic elements in follicular fluid adversely influence the likelihood of pregnancy and live birth in women undergoing IVF.

Study Question: Are follicular fluid (FF), arsenic (As), mercury (Hg), cadmium (Cd) and lead (Pb) concentrations associated with IVF outcomes among women undergoing IVF?

Summary Answer: There was a non-linear association between higher FF Hg concentration and a lower likelihood of biochemical pregnancy and live birth. Higher FF Pb concentration was also associated with a lower probability of live birth.

What Is Known Already: Previous research suggests that toxic elements may affect fertility among couples conceiving with and without assistance.

Concomitant tamoxifen or letrozole for optimal oocyte yield during fertility preservation for breast cancer: the TAmoxifen or Letrozole in Estrogen Sensitive tumors (TALES) randomized clinical trial.

Purpose: To determine whether concomitant tamoxifen 20 mg with gonadotropins (tamoxifen-gonadotropin) versus letrozole 5 mg with gonadotropins (letrozole-gonadotropin) affects mature oocyte yield.

Methods: Open-label, single-institution, randomized trial. Inclusion criteria included the following: females, ages 18-44 years old, with new diagnosis of non-metastatic breast cancer, who were undergoing fertility preservation with either oocyte or embryo cryopreservation.

Trace element analysis of human seminal plasma: A cautionary tale of preanalytical variation and use of non-traditional matrices in human biomonitoring studies.

Ensuring harmonization of (ultra-)trace element measurements in non-traditional matrices is a particular analytical challenge that is highlighted in this work for seminal plasma as part of the developmental core at the Wadsworth Center Human Health Exposure Analysis Resource Targeted Laboratory. Seminal plasma was collected from 39 male partners of women undergoing in vitro fertilization and analyzed by inductively coupled plasma tandem mass spectrometry (ICP-MS/MS) following deproteinization with concentrated HNO. Validation was accomplished using: 1) two aqueous NIST SRMs; 2) a seminal plasma QC pool, characterized via standard additions; 3) standard additions on a subset of samples; and 4) sample duplicates.

Conception after chemotherapy: post-chemotherapy method of conception and pregnancy outcomes in breast cancer patients.

Purpose: As the paradigm shifts towards improving cancer survivorship, an important concern for reproductive-aged women diagnosed with cancer is how their disease and its treatment will affect their future fertility. We sought to characterize pregnancy attempts and outcomes in breast cancer patients following chemotherapy.

Methods: We conducted a prospective cohort study of women diagnosed with breast cancer seen between 2010 and 2019.

Variability of essential and non-essential trace elements in the follicular fluid of women undergoing in vitro fertilization (IVF).

Both essential and non-essential elements have been associated with female reproductive function in epidemiologic investigations, including among IVF populations. To date, most investigators have used blood or urine to assess biomarkers of exposure, with few employing ovarian follicular fluid (FF). FF may offer a more direct "snapshot" of the oocyte microenvironment than blood or urine, however previous studies report follicle-to-follicle variability in FF constituents that may contribute to exposure misclassification.

A pilot investigation of couple-level phthalates exposure and in vitro fertilization (IVF) outcomes.

Phthalates are reproductive toxicants in experimental animal studies and exposure has been associated with infertility in human populations, although the results have been inconsistent. To help to address the data gap, we conducted a hypothesis-generating investigation of associations between urinary phthalate metabolites and reproductive outcomes among women (n = 56) and their male partners (n = 43) undergoing in vitro fertilization (IVF). Urine was collected from participants on the day of oocyte retrieval.

Is Preimplantation Genetic Testing Associated with Increased Risk of Abnormal Placentation After Frozen Embryo Transfer?

Objective: This study aimed to assess the association of preimplantation genetic testing (PGT) with abnormal placentation among a cohort of pregnancies conceived after frozen embryo transfer (FET).

Study Design: This is a retrospective cohort study of women who conceived via FET at the University of California, San Francisco from 2012 to 2016 with resultant delivery at the same institution. The primary outcome was abnormal placentation, including placenta accreta, retained placenta, abruption, placenta previa, vasa previa, marginal or velamentous cord insertion, circumvallate placenta, circummarginate placenta, placenta membranacea, bipartite placenta, and placenta succenturiata.

Sources of exposure to urinary phthalates among couples undergoing infertility treatment.

Phthalates have been implicated as reproductive toxicants in animal models and in human populations. This study examined associations between potential exposure sources and urinary phthalate metabolite concentrations among women (n = 56) and their male partners (n = 43) undergoing in vitro fertilization (IVF). On the day of oocyte retrieval, participants provided urine samples and completed questionnaires detailing use of personal care products (PCPs), and consumption of medications, foods, and beverages in the preceding 24 h.

Seafood consumption is associated with higher follicular fluid arsenic (As) and mercury (Hg) concentrations in women undergoing in vitro fertilization (IVF).

Human exposure to non-essential toxic metals such as cadmium (Cd), mercury (Hg), and lead (Pb), and metalloids such as arsenic (As) commonly occurs through diet. Toxic trace element exposures have been reported in association with fertility and fecundity in epidemiologic studies even at low to moderate levels. While most previous studies employed blood and urine biomarkers of exposure, few have assessed toxic trace elements in ovarian follicular fluid (FF), which surrounds the developing oocyte and hence may better reflect concentrations potentially affecting reproductive outcomes.

Ovarian stimulation for fertility preservation or family building in a cohort of transgender men.

Purpose: The purpose of this study was to compare ovarian stimulation and pregnancy outcomes between transgender men (1) with and without a history of testosterone use (HRT) and (2) to cisgender women.

Methods: Retrospective chart review between January 1st 2015 and March 1st, 2019 of transgender men and cisgender women seeking ovarian stimulation (OS) matched by BMI and age. Outcomes were compared using Fisher's exact or Wilcoxon's rank sum tests.

Back-to-back random-start ovarian stimulation prior to chemotherapy to maximize oocyte yield.

Purpose: To evaluate the feasibility of utilizing back-to-back random-start ovarian stimulation to increase oocyte yield for fertility preservation prior to cancer treatment.

Methods: A case series of 15 patients who underwent back-to-back random-start stimulation cycles prior to chemotherapy.

Results: Of the 15 back-to-back random-start stimulation cases, 13 had breast cancer and 2 had other cancers.

Ultra-trace element analysis of human follicular fluid by ICP-MS/MS: pre-analytical challenges, contamination control, and matrix effects.

Follicular fluid (FF), which is the fluid that envelops the developing oocyte (egg cell) in the ovary, can be analyzed to assess trace element content as well as to determine potential exposure to toxic elements in women seeking fertilization (IVF) treatment. Such measurements may be useful in establishing associations with potential adverse effects on oocyte viability and subsequent pregnancy outcomes. The principal goal of this study was to leverage the next generation of inorganic mass spectrometry based on ICP-MS/MS to address the numerous analytical challenges of (ultra-)trace element analysis of human FF specimens.

Results: Surveys were distributed to a total of 1135 members at 394 Society for Assisted Reproductive Technology clinics.

Random start ovarian stimulation for fertility preservation appears unlikely to delay initiation of neoadjuvant chemotherapy for breast cancer.

Study Question: Is random start ovarian stimulation associated with delays in initiation of neoadjuvant chemotherapy for breast cancer?

Summary Answer: Among women who complete fertility preservation (FP) consultation, random start ovarian stimulation is unlikely to delay time to initiation of neoadjuvant chemotherapy start.

What Is Known Already: Neoadjuvant chemotherapy is now a widely accepted treatment modality for operable breast cancer and random start ovarian stimulation is an increasingly-utilized modality for FP. While conventional ovarian stimulation does not appear to delay starting adjuvant chemotherapy, the relationship between random start ovarian stimulation and neoadjuvant chemotherapy start is not well-understood.
