BACKGROUND/PURPOSE: The role of LH during controlled ovarian stimulation (COS) in the general population remains contentious. There is no consensus on the indications for LH supplementation during COS. The purpose of this study is to determine whether menotropin supplement is associated with decreases in early pregnancy loss rates in patients exhibiting low endogenous LH during COS. METHOD: This is a single-center, retrospective cohort from a university-affiliated hospital...

Women with high-AMH levels have an increased risk of ovarian hyperstimulation syndrome (OHSS). Studies have suggested that highly purified menotropin (HP-hMG) Menopur® reduces the risk. We, therefore, studied use of low-dose (112.5 IU/day) HP-hMG in ovulatory and anovulatory patients with high AMH (>32 pmol/L). The primary endpoint was the distribution of patients with appropriate, excessive, and inadequate response (5-14, ≥15, and ≤4 oocytes). Another endpoint was frequency of OHSS. Totally 115 women were included and 78 (67...

STUDY QUESTION: Can gonadotrophin receptor variants separately or in combination, be used for the prediction of pregnancy chances in in vitro fertilization (IVF) trials? SUMMARY ANSWER: The luteinizing hormone/human chorionic gonadotrophin receptor (LHCGR) variant N312S and the follicle-stimulating hormone receptor (FSHR) variant N680S can be utilized for the prediction of pregnancy chances in women undergoing IVF. WHAT IS KNOWN ALREADY: The FSHR N680S polymorphism has been shown to affect the ovarian response in response to gonadotrophin treatment, while no information is currently available regarding variants of the LHCGR in this context...

BACKGROUND: The association of recombinant FSH (rFSH) plus recombinant LH (rLH) is currently used for Controlled Ovarian Stimulation (COS) in human IVF, but its efficacy has, to date, not yet been compared to that of human Menopausal Gonadotropin (hMG), the FSH + LH activity-containing urinary drug. METHODS: Eight hundred forty-eight (848) IVF patients classified as expected "poor" or "normal" responders according to antral follicle count (AFC) and basal (day 3) FSH were treated with rFSH + rLH (2:1 ratio, n = 398, Group A) or hMG (n = 450, Group B)...

OBJECTIVE: Severe factor V (FV) deficiency is rare. There are case reports describing pregnancy outcomes in women with FV deficiency and one case report of successful pregnancy following the use of fresh frozen plasma (FFP) in several cycles of ovulation induction and intrauterine insemination and at delivery. The authors report another case to support the use of FFP for reproduction. CASE: A 27-year-old woman with severe FV deficiency was given FFP at the time of ovulation induced with clomiphene citrate, human menopausal gonadotropin (hMG), and human chorionic gonadotropin...

A major cause of cycle cancellation during controlled ovarian hyperstimulation (COH) in women undergoing in vitro fertilization (IVF) is the occurrence of premature luteinizing hormone (LH) surges. Steroidal preparations can modulate the secretion of gonadotropins (Gn); however, few studies using progesterone to inhibit the premature LH surges in COH have been published. The purpose of the study was to evaluate the oral delivery of progesterone soft capsules (Utrogestan) to prevent LH surges from the follicular phase and to compare cycle characteristics as well as to evaluate pregnancy outcomes in subsequent frozen-thawed embryo transfer (FET) cycles...

BACKGROUND: With the use of new protocols Controlled ovarian hyperstimulation (COH) with lower doses of gonadotropins to the classics protocols and current trend of fewer embryos transferred, there is no agreement until today on the optimal dose start of a COH protocol. OBJECTIVE: Compare the results of two flexible protocols of HOC with different starting doses (150 vs 225 lU rFSH/hMG) plus a GnRH antagonist in cycles of IVF / ICSI. METHODS: Retrospective, descriptive study, we analyzed 231 cycles of IVF/ICSI being the primary variables: total FSH dose, dose increase, retrieved oocytes, embryos available for transfer and for cryopreservation...

The strategy of in vitro fertilization (IVF) procedures relies on the increasing pregnancy rate and decreasing the risk of premature ovulation and ovarian hyperstimulation syndrome. They are also designed to avoid weekend oocyte retrievals. Combined oral contraceptive (OC) pills are among the medicines used to accomplish these objectives. Alternatively, estradiol can be used instead of OC to obtain similar results. The aim of our study was to compare the differences in pregnancy rates (PRs), implantation rates, and miscarriage rates between a short agonist protocol with estradiol priming and a long protocol with combined OC...

OBJECTIVE: The objective of this study was to assess the relationship between BMI and oocyte number and maturity in participants who underwent minimal stimulation (mini-) or conventional IVF. METHODS: Participants who underwent their first autologous cycle of either conventional (n = 219) or mini-IVF (n = 220) were divided according to their BMI to analyze IVF outcome parameters. The main outcome measure was the number of oocytes in metaphase II (MII). Secondary outcomes included the number of total oocytes retrieved, fertilized (2PN) oocytes, cleavage and blastocyst stage embryos, clinical pregnancy (CP), and live birth (LB) rates...

STUDY QUESTION: Can controlled ovarian stimulation with low-dose human menopausal gonadotrophin (hMG) improve the clinical pregnancy rate when compared with ovarian stimulation with clomiphene citrate (CC) in an intrauterine insemination (IUI) programme for subfertile couples? SUMMARY ANSWER: Ovarian stimulation with low-dose hMG is superior to CC in IUI cycles with respect to clinical pregnancy rate. WHAT IS KNOWN ALREADY: IUI after ovarian stimulation is an effective treatment for mild male subfertility, unexplained subfertility and minimal-mild endometriosis, but it is unclear which medication for ovarian stimulation is more effective...

STUDY QUESTION: Is the treatment with recombinant FSH (rFSH) plus recombinant LH (rLH) more effective than highly purified (HP)-hMG in terms of ongoing pregnancy rate (PR) in women ≥35 years of age undergoing intrauterine insemination (IUI) cycles? SUMMARY ANSWER: The ongoing PR was not significantly different in women treated with rFSH plus rLH or with HP-hMG. WHAT IS KNOWN ALREADY: Although previous studies have shown beneficial effects of the addition of LH activity to FSH, in terms of PR in patients aged over 34 years having ovulation induction, no studies have compared two different gonadotrophin preparations containing LH activity in women ≥35 years of age in IUI cycles...

BACKGROUND: Administration of exogenous progesterone for luteal phase support has become a standard of practice. Intramuscular (IM) injections of progesterone in oil (PIO) and vaginal administration of progesterone are the primary routes of administration. This report describes the administration preferences expressed by women with infertility that were given progesterone vaginal insert (PVI) or progesterone in oil injections (PIO) for luteal phase support during fresh IVF cycles. METHODS: A questionnaire to assess the tolerability, convenience, and ease of administration of PVI and PIO given for luteal phase support was completed by infertile women diagnosed with PCOS and planning to undergo IVF...

BACKGROUND: New drugs effective against adult filariae (macrofilaricides) would accelerate the elimination of lymphatic filariasis and onchocerciasis. Anti-Onchocerca drug development is hampered by the lack of a facile model. We postulated that SCID mice could be developed as a fmacrofilaricide screening model. METHODS: The filaricides: albendazole (ABZ), diethylcarbamazine (DEC), flubendazole (FBZ), ivermectin (IVM) and the anti-Wolbachia macrofilaricide, minocycline (MIN) were tested in Brugia malayi (Bm)-parasitized BALB/c SCID mice vs vehicle control (VC)...

PROBLEM: We report on a successful ovarian stimulation and pregnancy in a patient with 'resistant ovary syndrome' (ROS) and antigonadotrophin antibodies. ROS is characterized by high endogenous gonadotrophins, low estradiol, normal ovarian antral follicle counts and normal antimuellerian hormone values. METHOD OF STUDY: After cyclical hormone treatment, downregulation with GnRH analogue and ICSI procedure followed. Granulosa cells were treated with LH, FSH or hMG and expression of receptors for FSH, LH, oestrogen receptor beta (ERb) and progesterone receptor A (PR-A) was determined...

OBJECTIVE: To report a case of a substance-induced psychotic disorder secondary to ovulation induction therapy with gonadotrophins. METHOD: Case report. RESULTS: We report a case of a psychotic episode secondary to gonadotrophins therapy. The acute episode was treated with antipsychotic (Aripiprazole). After 2 years the patient remains free of psychotic symptoms. CONCLUSION: There have been several reports correlating low levels of estrogen with psychotic symptoms, leading to studies evaluating the possible effect of this hormone as an antipsychotic...

AIM: Unexplained infertility affects 30% of infertile couples. Management depends on duration of infertility and age of female partner. Ovulation induction, together with intrauterine insemination, is commonly offered to couples with infertility of unknown origin. Intrauterine insemination gained its popularity because it is simple, non-invasive and cost-effective technique. The association with pharmacological stimulation is suitable to induce follicular maturation. The most used drugs to induce ovulation are clomiphene citrate and menopausal or recombinant gonodotropins...
