Hyperactivation and Tyrosine Phosphorylation of Cryopreserved Stallion Spermatozoa in Relation to Conventional In Vitro Fertilization Blastocyst Production

Andrology, EarlyView.
ABSTRACT Background Challenges in establishing clinical conventional in vitro fertilization (IVF) in horses include variation in sperm and oocyte quality, which can be affected by mare age. Extended preincubation of stallion spermatozoa has resulted in successful IVF.

Bioprospecting snakehead fish protein concentrate (SFC) as a non non-serumserum-based albumin source for promoting capacitation in bovine sperm

Journal of the Indonesian Tropical Animal Agriculture
Capacitation is a prerequisite for successful fertilization with albumin as an inevitable component among the oviductal fluid's constituents. Under in vitroenvironments, albumin's function is replaced by serum-based products, which carry the issue of ...

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

Experimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Regulation of Sperm Capacitation and the Acrosome Reaction by PIP 2 and Actin Modulation

Asian Journal of Andrology, 2015
Actin polymerization and development of hyperactivated (HA) motility are two processes that take place during sperm capacitation. Actin polymerization occurs during capacitation and prior to the acrosome reaction, fast F-actin breakdown takes place.

Graphene oxide affects in vitro fertilization outcome by interacting with sperm membrane in an animal model [PDF]

, 2018
We realized the exposure of boar spermatozoa to graphene oxide (GO) at concentration of 0.5, 1, 5, 10 and 50 μg/mL in an in vitro system able to promote the capacitation, i.e. the process that allows sperm cells to became fertile.

TMEM16A chloride channels in the female reproductive tract and their role in normal and dysfunctional pregnancy and labour

The Journal of Physiology, EarlyView.
Abstract figure legend TMEM16A plays a pivotal role in setting the duration of the action potential plateau in human uterine smooth muscle. An increase in TMEM16A expression in labour underpins a lengthening of the plateau and this provides time for the contraction to become larger and longer, important for timely successful labour.

Participation of epididymal cysteine-rich secretory proteins in sperm egg fusion and their potential use for male fertility regulation [PDF]

, 2007
Rat protein DE is an androgen-dependent cysteine-rich secretory protein (CRISP) synthesized by proximal epididymal regions. DE, also known as CRISP-1, is localized on the equatorial segment of acrosome-reacted spermatozoa and participates in gamete ...

Use of Pentoxifylline to Improve Seminal Parameters in Dogs

Veterinary Medicine and Science, Volume 12, Issue 3, May 2026.
A single oral dose of pentoxifylline (10 mg/kg) administered 40 min before ejaculation significantly improved sperm concentration and progressive motility in dogs. The effect was most pronounced in oligospermic subjects, supporting pentoxifylline as a rapid, well‐tolerated adjunct therapy for canine subfertility .

Reproductive physiology of the female cat [PDF]

, 2003
Ovarian cyclicity induces considerable changes in morphology, physiology and function of the reproductive organs in animals. This thesis aimed to study reproductive physiology of the female domestic cat, focusing on the cervix, uterus and uterine tube ...

Postcopulatory sexual selection [PDF]

, 2002
The female reproductive tract is where competition between the sperm of different males takes place, aided and abetted by the female herself. Intense postcopulatory sexual selection fosters inter-sexual conflict and drives rapid evolutionary change to ...
