OBJECTIVE: To review the literature concerning the effects of salpingectomy on ovarian function as assessed using measures of ovarian reserve and outcomes from in-vitro fertilization and spontaneous pregnancy cycles. BACKGROUND: Tubal surgery is performed for a variety of indications in gynecology. Salpingectomy is the most aggressive form of tubal surgery and may be performed for potential risk reduction for epithelial ovarian cancer, sterilization, ectopic pregnancy and as a method to enhance fertility in the setting of a hydrosalpinx...

BACKGROUND/AIMS: The study aimed to investigate the impact of fragile X mental retardation 1 (FMR1) pre-mutation status on blastocyst development in patients undergoing pre-implantation genetic diagnosis (PGD). METHODS: Case-control study of patients <40 years undergoing PGD at blastocyst stage for FMR1 pre-mutation status. Age-matched patients undergoing PGD for other single gene disorders were considered controls. Blastocyst development, calculated per metaphase II (MII) oocyte retrieved and per 2 pronuclear (2PN) embryos, was compared between the 2 groups...

OBJECTIVE: To compare the in vitro fertilization (IVF) outcomes between women with diminished ovarian reserve (DOR) after endometrioma operation and women with DOR without ovarian surgery. METHODS: This retrospective case-control study included 124 women aged under 40 and had DOR (serum anti-Müllerian hormone level <1.1 ng/mL or antral follicle count ≤6). They participated in fresh first and/or second IVF cycles between March in 2010 and December in 2015. Basal characteristics and IVF outcomes were compared between 47 cycles (32 women) with surgery-induced DOR and 119 cycles (92 women) with DOR without ovarian surgery...

Propagating genetically valuable individuals through oocyte collection, in vitro fertilization (IVF) and embryo transfer is critical to maintain sustainable populations of the endangered Eld's deer. The objectives of this study were to assess the impact of exogenous FSH injections on (1) the number and in vitro competence of oocytes collected and (2) the developmental potential of resulting IVF embryos after transfer into recipients during the breeding season (February-April). In a pilot experiment, estrus synchronization was conducted in three surplus females (using intravaginal progesterone-releasing devices, CIDRG for 14 days and injections of buserelin (a GnRH agonist)...

BACKGROUND: Although the increased risk for perinatal morbidity and mortality of babies born after ART is largely attributed to a higher rate of multiple gestations, a significantly worse perinatal outcome for singleton pregnancies following ART compared to pregnancies after natural conception has been reported as well. Most studies only include IVF/ICSI pregnancies; studies describing the perinatal outcome of pregnancies after non-IVF assisted reproduction are scarce. METHODS AND MATERIALS: Population-based cohort study with three exposure groups: a study group of pregnancies (1) after ovarian stimulation (OS), with or without artificial insemination (AI), (2) after IFV or ICSI and (3) a naturally conceived (NC) comparison group...

PURPOSE: Extracting ovarian tissue before oncologic therapy and transplanting it afterwards are increasingly being used to preserve fertility in women. This study describes standardized and safe operative procedures, with few complications, and reports the resulting ovarian function and pregnancy rates. METHODS: The standardized operative techniques for removing and transplanting ovarian tissue used at the Erlangen center are: for tissue removal, one-third to half of the tissue from one ovary is excised with scissors, without tissue coagulation; for subsequent transplantation, pieces of ovarian tissue are placed in a retroperitoneal pocket without closure of the pocket...

BACKGROUND: Pregnancy luteoma is a distinctive non-neoplastic hormone dependent lesion arising in pregnancy and mimicking an ovarian tumour. Fewer than 200 cases have been described in the English-language literature. Its clinical and morphological features are characteristic and must be considered in order to prevent diagnostic misinterpretation. To the best of our knowledge the association of pregnancy luteoma with endometriosis has not been reported in literature to date. CASE REPORT: A 30-year-old pregnant woman with no particular past medical history, consulted her gynaecologist at 17 weeks gestation for routine check-up...

PURPOSE: The purpose of this study was to determine the diagnostic accuracy of MRI for detecting acute appendicitis in pregnancy in a multi-institution study involving general body MR readers with no specific expertise in MR imaging of the pregnant patient. METHODS: Retrospective review of MRI examinations on PACS in 42 pregnant patients was evaluated for acute right lower quadrant pain. Three fellowship-trained general body radiologists analyzed the MRI examinations in consensus and attempted to localize the appendix, assess for features of appendicitis, and exclude alternative etiologies for the right lower quadrant pain...

The transforming growth factor β (TGF-β) family has a profound impact on the reproductive function of various organisms. In this review, we discuss how highly conserved members of the TGF-β family influence the reproductive function across several species. We briefly discuss how TGF-β-related proteins balance germ-cell proliferation and differentiation as well as dauer entry and exit in Caenorhabditis elegans. In Drosophila melanogaster, TGF-β-related proteins maintain germ stem-cell identity and eggshell patterning...

The low take-home baby rate in older women in Australia (5.8%) undergoing IVF is linked to the depletion of the ovarian reserve of primordial follicles. Oocyte depletion causes an irreversible change to ovarian function. We found that the young patient FSH receptor and LH receptor expression profile on the granulosa cells collected from different size follicles were similar to the expression profile reported in natural cycles in women and sheep. This was reversed in the older patients with poor ovarian reserve...

The aim of this retrospective study was to determine the clinical pregnancy rate in women undergoing letrozole ovarian stimulation and artificial insemination by donor (AID). Between 2012 and 2015, 130 natural cycles, 939 letrozole cycles and 130 letrozole plus gonadotrophin cycles were conducted. Letrozole cycles were divided into three groups according to LH concentration on the day of HCG administration (LH <10 mIU/ml and follicle size ≥18 cm; LH ≤10 to <20 mIU/ml; and LH ≥20 mIU/ml). Pregnancy rates were 17...

: Identifying the etiology of acute pelvic pain in girls is often clinically challenging. Particularly in young girls, it is often difficult to determine if acute pelvic symptoms are originating from a gynecologic source or from a genitourinary or gastrointestinal etiology based on the child's clinical examination alone. Therefore, imaging plays a key role in establishing a diagnosis and in directing medical and surgical treatment. Pediatric gynecologic conditions, which can present acutely with pain or mass or both include ovarian torsion, hematometrocolpos, pelvic inflammatory disease, inguinal hernias containing an ovary or the uterus or both, adnexal cysts, pregnancy, vaginal foreign bodies, and ovarian vein thrombosis...

In 1990, two selection lines of Merino sheep were established for low and high behavioural reactivity (calm and nervous temperament) at the University of Western Australia. Breeding records consistently showed that calm ewes weaned 10% to 19% more lambs than the nervous ewes. We hypothesise that calm ewes could have a higher ovulation rate than nervous ewes and/or calm ewes could have a lower rate of embryo mortality than nervous ewes. We tested these hypotheses by comparing the ovulation rate and the rate of embryo mortality between the calm and nervous lines before and after synchronisation and artificial insemination...

PURPOSE: Surrogacy remains the only option for having a biologic child for a unique population of women with severe medical conditions. However, no study has looked at surrogacy outcome as a result of the type of ovarian stimulation of the intended mother [controlled ovarian stimulation (COH), modified natural cycle (MNC), and in vitro maturation (IVM)] for oocyte retrieval. METHODS: This is a retrospective study, including all intended mothers and gestational carriers in a tertiary, university affiliated, medical center, from 1998 to 2016...

The current study aimed to investigate the effects of luteal gonadotropin-releasing hormone (GnRH) antagonist pretreatment on the outcomes of diminished ovarian reserve (DOR) patients who were treated using a FSH/letrozole/GnRH antagonist (FLA) protocol. Thus, patients who had luteal GnRH antagonist pretreatment (AFLA) prior to stimulation were compared to patients who had the FLA protocol, only. An electronic database was used to identify patients and stimulation characteristics. Women who had a total antral follicle count (AFC) of <7 were included in the analysis...

REVIEW
Michael M Alper, Bart C Fauser
Conventional ovarian stimulation protocols for IVF are designed to achieve maximum oocyte yields. Conventional protocols, however, are associated with patient discomfort, increased risk of ovarian hyperstimulation syndrome and higher costs. In recent years, mild stimulation protocols have risen in popularity. These protocols typically use lower doses (≤150 IU/day), shorter duration of exogenous gonadotrophins, or both, compared with conventional protocols, with the goal of limiting the number of retrieved oocytes to less than eight...

This study aimed to correlate the inflammatory reaction (IR) caused by a progesterone-releasing intravaginal device (P4) with ovarian activity and pregnancy rate (PR) in embryo-recipient anestrus mares (to decrease the spring transitional period). 50 animals were assigned to three groups: GP4 (P4 group; n = 16), GP4OH (P4 + oxytetracycline hydrochloride and hydrocortisone sprayed onto the device; n = 14), and GNP4 (no intravaginal P4; n = 20). The administration protocol for GP4 was: Day 0, 750 mg P4 + ovarian examination by ultrasonography (US) + vaginal sample collection; Day 8, US; Day 11, P4 removal + 7...

The objective of the present study was to determine the ovarian response induced with the prostaglandin-based protocol Synchrovine (two doses of PGF2α given 7 d apart), as well as the fertility after FTAI. In Experiment 1, 15 females received the Synchrovine protocol using two different PGF2α analogues (Delprostenate vs. D-Cloprostenol). No differences in estrus response, time of ovulation and follicular dynamics were found between both groups (P < 0.05). The ovulation after Synchrovine was synchronized in a similar mean interval (68...

REVIEW
B Lawrenz, H M Fatemi
The premature rise of progesterone during the late follicular phase in stimulated IVF cycles is a frequent event, and emerging evidence shows that premature progesterone rise does negatively affect the outcome of assisted reproductive techniques. The effect of elevated peripheral progesterone levels in the late follicular phase seems to be on the endometrium and the window of implantation, which may lead to asynchrony between the endometrium and the developing embryo. In stimulated cycles, endometrial maturation is advanced on the day of oocyte retrieval, and patients with a progesterone level above 1...
