Comparing CIDR with progesterone injections and eCG with human recombinant FSH for synchronizing estrous cycle in ewes.

Background: It is desirable in estrus synchronization in sheep to avoid intravaginal devices and to shorten the program from 14 to 6 days. Moreover, replacement of eCG with safe, cheap, and efficient gonadotropin is in worldwide demand.

Aims: This study investigates the possibility of replacing eCG with human recombinant FSH (hrFSH) and CIDR with progesterone injections for estrous synchronization in ewes.

A preliminary report comparing the effect of Asafoetida with oral contraceptive on polycystic ovarian syndrome in a double-blind randomized trial.

Objective: Polycystic ovarian syndrome (PCOS) is the most common cause of infertility and endocrine disorders in women of childbearing age. In Persian medicine, L. (Asafoetida) was recommended for treating PCOS.

Effect of Intra-ovarian Injection of Mesenchymal Stem Cells or its Conditioned Media on Repeated OPU-IVEP Outcomes in Jersey Heifers and Its Relationship with Follicular Fluid Inflammatory Markers.

Background: Repeated Ovum Pick Up (OPU) could have a detrimental effect on ovarian function, reducing Embryo Production (IVEP). The present study examined the therapeutic effect of adipose-derived Mesenchymal Stem Cells (MSCs) or its Conditioned Medium (ConM) on ovarian trauma following repeated OPU. Resolvin E1 (RvE1) and Interleukin-12 (IL-12) were investigated as biomarkers.

Camel semen collection, viscosity, and cryopreservation: a review.

Artificial insemination in camels remains undeveloped due to the difficulties in semen collection, semen viscosity, and semen cryopreservation. The semen collection procedure has been facilitated to some extent using camel phantom and/or possibly an intravaginal condom. Main reasons for semen viscosity in camelids have been unraveled and different mechanical and enzymatic approaches were used to alleviate this problem; however, there is still no conclusive protocol to safely remove semen viscosity completely.

The effect of varying concentrations of chicken plasma egg yolk and glycerol on the viability of canine sperm following short and long-term preservation.

Background: Plasma egg yolk (PEY), due to simple preparation and easier access, could be a suitable alternative to raw egg yolk for preserving canine semen.

Aims: The present study investigated suitable concentrations of PEY and glycerol for preservation of canine semen.

Methods: Semen was collected by digital manipulation (seven replicates from four dogs).
