Progestin Primed Double Stimulation Protocol Versus Flexible GnRH Antagonist Protocol in Poor Responders

The worldwide prevalence of primary and secondary infertility is estimated at
2% and 10.5%, respectively, among women aged 20-44 years and attempting to conceive. Poor ovarian responders (PORs) involve 9-24% of patients undergoing in-vitro fertilization (IVF). proper tailoring of the ovarian stimulation protocol in order to maximize the number of oocytes collected represents a crucial step for them to eventually conceive.
Recent evidence indicates that in the same menstrual cycle, there are multiple follicular recruitment waves. This coincides with the theory that folliculogenesis occurs in a wave-like fashion. Thus, within a single menstrual cycle, there can theoretically be multiple opportunities for a clinician to collect oocytes, as opposed to the conventional single cohort of antral follicles during the follicular phase.
Utilizing this concept, clinicians have been attempting to retrieve oocytes from poor responders using both the follicular-phase stimulation (FPS) and the luteal-phase stimulation (LPS) protocols to increase the number of oocytes collected shorter within shorter period of time. By increasing the number of the retrieved oocytes collected, a better clinical can be assured since there is a clear relationship between the number of oocytes collected and live birth rates across all female age groups.
which protocol is the most effective remains controversial and the efficacy of PPOS in POR compared with that of conventional protocols is unclear.

Quality evaluation of highly purified human menopausal gonadotropin preparations by means of gel electrophoresis and mass spectrometry.

Article

作者: Dorrer, V ; Noe, M ; Muqaku, L ; Noe, C R ; Nebija, D

Human gonadotropins are glycoprotein hormones with a highly complex structure, which demands the application of sophisticated analytical methodologies to assess their quality. The principal objective of this study was a comparative evaluation of gel electrophoretic techniques and mass spectrometry-based methods for the quality study of the two urinary-derived, highly purified, human menopausal gonadotropin preparations, Menopur 75/75 I. U. and Meriofert 75 I. U. Molecular mass (Mr), isoelectric point (pI), and isoform pattern of studied compounds were estimated via SDS-PAGE and 2D gel electrophoresis, whereas matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) was used for the downstream characterization of peptides obtained after in-gel tryptic digestion of selected protein spots. Additionally, for the estimation of the glycosylation pattern of these biologics, the enzymatic release of oligosaccharides was performed, and the isoform pattern was studied. Gel electrophoresis showed a typical electrophoretic behaviour for protein biotherapeutics medicines consisting of extremely complex spot patterns migrating at different masses and pIs. MS analysis proved to be a powerful tool for the identification and detailed characterization of the gonadotropins and the relevant peptides were identified with high sequence coverages. The results of this study are not only useful for the quality assessment of this class of complex biopharmaceuticals but may also serve as a supporting platform for further development of biopharmaceuticals based on modulation of the glycosylation pattern to enhance efficacy or reduce side effects.

The effect of human menopausal gonadotropin and equine chorionic gonadotropin on the reproductive performance of treated ewes with short‐term progesterone injections and sponge during the non‐breeding season

Article

作者: Zeyghami, Abbas ; Mirzaei, Abdolah ; Sorkh, Shahram Dehghani Ghale

AbstractThis study investigated the effect of human menopausal gonadotropin (hMG) on reproductive efficiency of synchronized ewes with the sponge and progesterone (P4) injection‐based protocols. In study 1, anoestrous ewes (n = 120) were used. Sixty ewes were treated with sponge (S) for 12 days. The injection of eCG (SeCG group, n = 30) or hMG (ShMG, n = 30) was given at the time of sponge removal. Thirty ewes received IM injection of P4, three times every 48 h and the injection of hMG was given 24 h after the third P4 injection (3PhMG group, n = 30), and 30 ewes were used as control group. Pregnancy was diagnosed on day 50 after the release of ram. In study 2, 60 ewes were randomly divided into two equal groups. In the treated group with antibiotics (n = 30), before inserting, the sponges were impregnated with the antibiotic penicillin G sodium (5,000,000 IU) and in the control group (n = 30), there was no added antibiotics. Before inserting and after removing sponges, a vaginal cytology sample was taken with a sterile cotton swab. The number of neutrophils in each sample was counted and analysed. The rate of oestrus and total pregnancy was greater in SeCG (96.7, 93.3%), ShMG (82.8, 93.1%) and 3PhMG (67.9, 89.3%) groups compared with the control group (13.8, 41.4%) (p < .05). No significant difference was found in single, twin and total lambing and pregnancy rates after injection of eCG and hMG during the non‐breeding season (p > .05). A higher percentage of control ewes had the vaginal smear with neutrophils more than 50% (96.7% vs. 76.7%; p < .05). In conclusion, a single dose of hMG can induce fertile oestrus in synchronized ewes with P4 administered by either injection or intravaginally. Purulent discharge and percentage of neutrophils were significantly reduced in the synchronized ewes by the impregnated sponges with the antibiotic penicillin.

Vaginal micronized progesterone on preventing luteinizing hormone untimely surge in ART cycles: A prospective proof-of-concept study

Article

作者: Souza, Marcelo Marinho de ; Barbeitas, Ana Luiza ; Raupp, Veronica de Almeida ; Souza, Maria do Carmo Borges de ; Rebello, Dandhara Martins ; Mancebo, Ana Cristina Allemand ; Antunes, Roberto de Azevedo

OBJECTIVEA new approach to evaluate whether Progestin-Primed Ovarian Stimulation with micronized vaginal progesterone was as effective as using dydrogesterone in suppress LH pulse surge in young women under stimulation in an oocyte donor programme.METHODSThis prospective study included 21 patients aged 19 to 32 years-old stimulated with Elonva® 150, associated or not with Menopur® or Merional® (75 or 150IU) since the beginning of the cycle, plus HMG 150-225IU after the 8th day or just HMG 150-300IU per day. Patients were placed in a PPOS protocol with micronized vaginal progesterone (MVP) 200 mg (Gynpro® Exeltis or Junno Farmoquimica) every 12 hours or dydrogesterone (Duphaston® Abbott) 10 mg every 8 hours from the start of stimulation until the day after the GnRH trigger with Triptorelin 0.2 mg (Gonapeptyl daily®). The primary endpoint was the prevention of untimely LH surge, and secondarily the number of 16 mm follicles, retrieved oocytes and metafase II.RESULTSFourteen oocyte donor patients were prescribed MVP while seven others received dydrogesterone (DYG).The gonadotropin protocols included 04 with Corifollitropin alfa 150 plus HMG since the beginning and complemented after the 7th day, and 17 times of just HMG. There was no diferences in the number of follicles >10≤15mm, ≥16mm or number of metafase II oocytes. There was no untimely LH surge on both groups and no OHSS was developed after the agonist trigger.CONCLUSIONSProgestin-Primed Ovarian Stimulation with micronized vaginal progesterone seems to be a compelling choice for preventing premature ovulation without compromising oocyte quality in women undergoing ovarian stimulation.
