BACKGROUND: Poor ovarian response (POR) to ovarian hyperstimulation is one of the biggest challenges in assisted reproduction technology. The objective of this study was to compare the efficacy of progestin-primed ovarian stimulation (PPOS) with a GnRH antagonist (GnRH-ant) in poor ovarian response (POR) patients. MATERIALS AND METHODS: This retrospective analysis included a total of 186 cycles of POR patients between 2014 and 2016. The patients were divided into two groups according to the method of stimulation protocol, as follows: 63 cycles were PPOS, and 123 cycles were GnRH-ant...

Mitochondrial dysfunction is related to reproductive decline in humans, with consequences for in vitro fertilization (IVF). We assessed whether dehydroepiandrosterone (DHEA) could regulate mitochondrial homeostasis and mitophagy of cumulus cells (CCs) in poor ovarian responders (PORs). A total of 66 women who underwent IVF treatment at the Reproductive Medicine Center of Kaohsiung Veterans General Hospital were included in this study. Twenty-eight normal ovarian responders (NOR) and 38 PORs were enrolled. PORs were assigned to receive DHEA supplementation ( n = 19) or not ( n = 19) before IVF cycles...

BACKGROUND: Dehydroepiandrosterone (DHEA) is now widely used as an adjuvant for in vitro fertilization (IVF) cycles in poor ovarian responders (PORs). Several studies showed that DHEA supplementation could improve IVF outcomes of PORs. However, most of the PORs do not respond to DHEA clinically. Therefore, the aim of this study is to confirm the beneficial effects of DHEA on IVF outcomes of PORs and to investigate which subgroups of PORs can best benefit from DHEA supplementation. METHODS: This retrospective cohort study was performed between January 2015 and December 2017...

RESEARCH QUESTION: Is minimal ovarian stimulation (MOS) as effective as conventional ovarian stimulation (COS) in ovarian response and embryo quality in the same 46 poor-responder patients according to the Bologna criteria? DESIGN: An intra-patient comparison of patients undergoing both protocols. Ovaries were stimulated with either a gonadotrophin-releasing hormone antagonist protocol and a combination of recombinant FSH and highly purified human menotrophin (HP-HMG) daily (COS), or with the use of clomiphene citrate 50 mg daily and 150 IU of HP-HMG or recombinant FSH every other day from simulation day 4 (MOS)...

The theory of a multicyclic development of follicles during the menstrual cycle prompted new approaches to ovarian stimulation, such as starting gonadotrophins for ovarian stimulation at any time during the menstrual cycle or using double stimulation during it, with stimulation in both the follicular and luteal phases. Because of the asynchrony between endometrial receptivity and embryo development with a 'non-conventional start' stimulation, all the oocytes/embryos are generally cryopreserved and transferred subsequently...

Background: Ovarian carcinosarcoma is a rare malignancy associated with a high rate of cancer-related mortality even at early stages. Guidelines for systemic treatment have been difficult to establish because the disease is commonly excluded from prospective clinical trials. Ovarian carcinosarcoma is usually managed as high-grade epithelial ovarian cancer despite major histologic differences. Owing to the rarity and poor prognosis of ovarian carcinosarcoma, salvage treatments and their efficacy have been poorly described...

INTRODUCTION: Women with infertility who have a poor ovarian responder (POR), characterized by a low number of retrieved oocytes after ovulation induction, often have a significantly reduced pregnancy rate after in vitro fertilization-embryo transfer (IVF-ET), due to the few transferred embryos. Acupuncture is a form of Korean Traditional Medicine. It involves the insertion of a microscopic needle at a specific point in the body, known as an acupuncture point or an acupoint. In this study, our purpose is to investigate how acupuncture affects the retrieval of mature oocytes after ovulation induction in patients with POR...

BACKGROUND: Progress in vitrification techniques has allowed reproductive physicians to consider new strategies for using progestin as an alternative to a GnRH analogue to improve in vitro fertilisation (IVF). However, the role of progestin in blocking luteinising hormone (LH) surges and its potential in clinical practice are unclear, especially for poor responders. We designed a prospective randomised controlled trial (RCT) to compare the efficacy of a gonadotropin-releasing hormone (GnRH) antagonist and progestin in blocking LH surges and premature ovulation in poor responders...

Poor responders are described as those In Vitro Fertilization (IVF) patients who are failing to respond to controlled ovarian stimulation protocols. Extensive research has focused on crafting the optimal treatment. However, it appears that each approach fails to be established as effective or guaranteed towards successful management. Platelet-Rich Plasma (PRP) is a novel, highly promising approach that has been successfully applied for an array of medical issues. In this case series, we present 3 poor responder patients with the common denominator of: failed IVF attempts, poor oocyte yield, and poor embryo quality...

Does corifollitropin alfa associated with hp-HMG protocol from the beginning of ovarian stimulation perform better than high dose rFSH alone for ovarian stimulation with GnRH antagonist in poor responders? This retrospective, monocentric, case-control pilot study was conducted in 65 poor responders (Bologna criteria) undergoing 2 consecutive IVF cycles. All patients underwent a first ovarian stimulation cycle with high dose rFSH (≥300 IU/day) alone in antagonist protocol, unfortunately leading to poor ovarian response and no pregnancy...

Previous studies indicated that progesterone can be withdrawn at the time of the first positive β-hCG test without compromising the clinical pregnancy outcome in normal ovarian responder. However, the effect of early stop of progesterone supplementation for patients with poor ovarian response (POR) has not been investigated. This study retrospectively collected data from patients with POR in 156 IVF/ICSI fresh embryo transfer (ET) cycles in single tertiary center from January 2010 to June 2016. All the patients met ESHRE consensus, the Bologna criteria, of POR and had hCG injection for luteal phase support (LPS) on day 2, 5 and 8 after ovum pick-up...

Our In-Vitro Fertilisation Centre is situated in a large developing country, Madagascar, with very bad roads and low income patients. Therefore we try to find ways to reduce as much as possible the number of attempts to obtain a pregnancy. Poor or no response to ovarian stimulation in In Vitro Fertilization (IVF) cycles is a great challenge. Here we describe a method whereby we shift from IVF to Oocyte Donation (OD) during the same cycle for patients whose ovaries do not respond properly to ovulation stimulation...

STUDY QUESTION: Is the length of the anogenital distance (AGD) a biomarker of ovarian reserve and response to controlled ovarian stimulation (COS)? SUMMARY ANSWER: Shorter AGD is associated with presence of poor ovarian response. WHAT IS KNOWN ALREADY: Organ development during prenatal life is influenced by the prevailing intrauterine environment, and it has been suggested that nutritional, environmental and toxic factors could affect ovarian reserve set prenatally...

BACKGROUND: Fragile-X-Mental-Retardation-1- (FMR1)-gene is supposed to be a key gene for ovarian reserve and folliculogenesis. It contains in its 5'-UTR a triplet-base-repeat (CGG), that varies between 26 and 34 in general population. CGG-repeat-lengths with 55-200 repeats (pre-mutation = PM) show instable heredity with a tendency to increase and are associated with premature-ovarian-insufficiency or failure (POI/POF) in about 20%. FMR1-mRNA-expression in leucocytes and granulosa cells (GCs) increases with CGG-repeat-length in PM-carriers, but variable FMR1-expression profiles were also described in women with POI without PM-FMR1 repeat-length...

RATIONALE: Ovarian malignancy is associated with one of the highest rates of death among gynecological reproductive system malignancies. While progress has been made in surgical and postoperative adjuvant treatment approaches, the early atypical clinical manifestations, quick progression, and lack of the effective early screening means imply that the prognosis remains poor. Bilateral ovarian cancers are common, but different types of primary bilateral ovarian carcinomas are extremely rare...

BACKGROUND: Arylamine N-acetyltransferase 1 (NAT1) is a drug metabolizing enzyme that has been associated with cancer cell proliferation in vitro and with survival in vivo. NAT1 expression has been associated with the estrogen receptor and it has been proposed as a prognostic marker for estrogen receptor positive cancers. However, little is known about the distribution of NAT1 mRNA across an entire patient population or its effects on outcomes. To address this, gene expression data from breast cancer patient cohorts were investigated to identify sub-populations based on the level of NAT1 expression...
