Modulation of gonadotropins activity by antibodies

, 2019
International audienceGonadotropins are essential for reproduction control in humans as well as in animals. They are widely used all over the world for ovarian stimulation in women, spermatogenesis stimulation in men, and ovulation induction and ...

Transgenic Drosophila Expressing Active Human LH Receptor in the Gonads Exhibit a Decreased Fecundity: Towards a Platform to Identify New Orally Active Modulators of Gonadotropin Receptor Activity

Pharmaceuticals
Background/Objectives: The gonadotropins luteinizing hormone (LH) and follicle-stimulating hormone (FSH) and their receptors are major regulators of reproduction in mammals and are absent in insects.

Association Between the Ratio of Ovarian Stimulation Duration to Original Follicular Phase Length and In Vitro Fertilization Outcomes: A Novel Index to Optimise Clinical Trigger Time

Frontiers in Endocrinology, 2022
The duration of ovarian stimulation which is largely dependent on the ovarian response to hormonal stimulation may influence in vitro fertilization (IVF) outcomes.

Gonadotropins and prostate cancer: revisited.

, 2006
Luteinizing hormone and follicle-stimulating hormone are called gonadotropins, because they stimulate the gonads – in males the testes and in females the ovaries. They are not necessary for life, but are essential for reproduction.

OVARIAN STIMULATION FOR IVF-ET PROCEDURE

Zdravniški Vestnik, 2002
Background. It is well known that the efficiency of fertilization in vitro depends on the number of transferred embryos. To provide the conditions for the development of a higher number of ovarian follicles, from which a higher number of oocytes can be ...

Pregnancy outcome of assisted reproductive technology cycle in patients with hypogonadotropic hypogonadism

Journal of Human Reproductive Sciences, 2015
CONTEXT: Ovulation induction in patients with hypogonadotropic hypogonadism (HH) is a challenge to the treating physician. The threshold for ovarian response in HH may differ substantially from that of normal patients.

Generation and use of recombinant gonadotropins in fish

, 2020
Understanding the differential roles of the pituitary gonadotropins Fsh and Lh in gonad maturation is crucial for a successful manipulation of the reproductive process in fish, and requires species-specific tools and appropriate active hormones. With the

Undissociable chemically cross-linked and single-chain gonadotropins

, 2023
International audienceUndissociable gonadotropins can be obtained either by chemical cross-linking of the natural heterodimeric hormones or by expressing recombinant single-chain molecules through the fusion of their a and I3 polypeptide sequences. These

Testicular “Hyperstimulation” Syndrome: A Case of Functional Gonadotropinoma

Case Reports in Endocrinology, 2014
Gonadotropins secreting pituitary tumors tend to present as sellar mass with hypogonadism. Biologically active LH secretion by these tumors resulting in elevated testosterone is extremely rare. We report a case of a 48-year-old male patient who presented

Ovulation induction with clomiphene or gonadotropins

, 2005
Clomiphene citrate (CC) results in ovulatory cycles in about 75–90% of patients with PCOS and is particularly successful in the leaner, oligomenorrheic non-amenorrheic patient with only limited signs of hyperandrogenism.
