Recent advances in the superovulation in cattle [PDF]

Reproduction Nutrition Development, 2002
The variability in the superovulatory response continues to be one of the most frustrating problems with embryo transfer in cattle. The removal of LH from pituitary extracts has tended to reduce the variability in response, and several studies involving the use of the purified porcine pituitary extract. Folltropin-V are reviewed.

Advances in the Use of Recombinant Gonadotropins for Reproductive Biotechnologies in Ruminants: A Review

Reproduction in Domestic Animals, Volume 61, Issue 5, May 2026.
ABSTRACT Recombinant gonadotropins, particularly recombinant follicle‐stimulating hormone (rFSH) and recombinant equine chorionic gonadotropin (reCG), have emerged as viable alternatives to traditional animal‐derived hormones in reproductive biotechnologies. This review aims to provide an updated and comprehensive overview of recombinant gonadotropins,

Histomorphometric Evaluation of Superovulation Effect on Follicular Development after Autologous Ovarian Transplantation in Mice

Veterinary Medicine International, 2015
The effect of superovulation by pregnant mare serum gonadotropin (PMSG) on autologous transplanted ovaries in the lumbar muscles of mice was histomorphometrically evaluated using the indices of number and volume of different kind of follicles and volume ...

Hepatic lipase gene expression is transiently induced by gonadotropic hormones in rat ovaries [PDF]

, 1997
Hepatic lipase (HL) gene expression was studied in rat ovaries. A transcript lacking exons 1 and 2 could be detected by reverse transcription-polymerase chain reaction (RT-PCR) in the ovaries of mature cyclic females and of immature rats treated with ...

TMC4 localizes to multiple taste cell types in the mouse taste papillae

FEBS Open Bio, Volume 16, Issue 4, Page 778-787, April 2026.
Transmembrane channel‐like 4 (TMC4), a voltage‐dependent chloride channel, plays a critical role in amiloride‐insensitive salty taste transduction. TMC4 is broadly expressed in all mature taste cell types, suggesting a possible involvement of multiple cell types in this pathway.

COITAL BLOCK TO SUPEROVULATION IN THE HAMSTER [PDF]

Reproduction, 1963
Summary. Hamsters injected with 60 i.u. pregnant mares' serum (pms) on the morning of metoestrus (Day 1 of oestrous cycle) will ovulate sixty to seventy ova if they are isolated from males. However, if similarly treated females are caged with males on Day 2 or 3, coitus takes place and the inactive corpora lutea of the oestrous cycle ...

Genomic Variants Associated With Oocyte and Embryo Production in Dairy Gir Cattle

Animal Genetics, Volume 57, Issue 2, April 2026.
ABSTRACT The use of in vitro fertilization protocols associated with genomic selection increases genetic gain in dairy cattle. The aims of this study were to uncover genetic variants in a specific interval on BTA7 and to investigate their effects on the number of oocytes and embryos in dairy Gir.
