An externally validated age-related model of mean follicle density in the cortex of the human ovary [PDF]

, 2015
The population of non-growing follicles present in the ovary is defined as the ovarian reserve. This underpins the reproductive lifespan in women, with its depletion determining age at loss of fertility and the menopause.

New approaches to ovarian stimulation [PDF]

Human Reproduction, 1998
Suppression of endogenous hormone production by gonadotrophin-releasing hormone (GnRH) agonists followed by controlled ovarian hyperstimulation (COH) with human gonadotrophins, especially the so-called 'long protocol' has developed from second-line into first-line therapy.

External validation of anti-Müllerian hormone based prediction of live birth in assisted conception [PDF]

, 2013
<p>Background - Chronological age and oocyte yield are independent determinants of live birth in assisted conception. Anti-Müllerian hormone (AMH) is strongly associated with oocyte yield after controlled ovarian stimulation.

Exploiting LH in ovarian stimulation

Reproductive BioMedicine Online, 2006
During intermediate-late phases of human folliculogenesis, LH plays a key role in promoting steroidogenesis and growth of the leading follicle. Ovarian stimulation for assisted reproduction techniques usually consists of administering exogenous FSH in a low LH environment.

Improving fertility preservation in cancer: ovarian tissue cryobanking followed by ovarian stimulation can be efficiently combined

, 2011
This pilot study evaluated whether combination of partial removal of ovarian tissue for cryobanking followed by ovarian stimulation and cryopreservation of oocytes can improve the efficacy of fertility preservation without further delaying cancer ...

Evaluating the role of serum AMH in predicting suboptimal or excessive ovarian response to standard dosing regimen of ovarian stimulation in in-vitro fertilisation using GNRH agonist long protocol [PDF]

, 2011
Introduction: Antral follicle count (AFC) is widely used for individualising gonadotrophin dosage in in-vitro fertilisation (IVF) treatment. This retrospective study tried to determine whether baseline serum anti-Mullerian hormone (AMH) measurement ...

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation

FEBS Letters, EarlyView.
Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...
