TLDR
Results indicate that collections conducted in spring yield higher number of spermatozoa, when the libido of males is also at a maximum, and seasonal variation in semen quality should be considered in breeding programmes by artificial insemination to maximise fertility.About:

Aamir Nawab,Fahar Ibtisham,Guanghui Li,Barbara Kieser,Jiang Wu,Wenchao Liu,Yi Zhao,Yasir Nawab,Kongquan Li,Mei Xiao,Lilong An +10 more
TL;DR: There exists a crucial need to explore effective strategies including genetic markers to enhance thermo-tolerance and productivity of poultry birds in hot regions of the world.

Climate change and heat stress: Impact on production, reproduction and growth performance of poultry and its mitigation using genetic strategies.
TL;DR: In this paper, the authors reviewed the impact of heat stress on production, reproduction and growth performance of poultry, and its alleviation using genetic strategies, and concluded that there is a critical need of formulating selection strategies based on genetic markers and exploring more genes in addition to HSP25, 70, 90, H1, RB1CC, BAG3, PDK, ID1, Na, F, dw and K responsible for thermoregulation, to improve the overall performance of birds along with their ability to tolerate heat stress conditions.

Extreme temperatures compromise male and female fertility in a large desert bird.
Mads Fristrup Schou,Maud Bonato,Anel Engelbrecht,Zanell Brand,Erik I. Svensson,Julian Melgar,Pfunzo T. Muvhali,Schalk Cloete,Charlie K. Cornwallis +8 more
TL;DR: Schou et al. as mentioned in this paper used two decades of data from a large experimental breeding program of the iconic ostrich (Struthio camelus) in South Africa, and found that the number of eggs females laid and number of sperm males produced were highly sensitive to natural temperature extremes (ranging from −5°C to 45°C).

The Usefulness of Captive Kept Capercaillie (Tetrao urogallus L.) as the Semen Donors for Artificial Insemination and Gene Pool Preservation In vitro
Ewa Łukaszewicz,Artur Kowalczyk +1 more
TL;DR: Evaluated results indicate that majority of capercaillie kept in captivity, both young (2-3 years old) and older (up to 10 years old), can be valuable semen producers in succeeding seasons.

Relationship between spermatozoan lipid composition and fertility during aging of chickens.
TL;DR: The results suggest that the lipid and fatty acid compositions of spermatozoa may be important predictors of fertility.

Fertility of Male and Female Broiler Breeders Following Exposure to Elevated Ambient Temperatures
TL;DR: The male bird appears to contribute more to heat stress infertility than the female, and egg fertility was decreased when hens were inseminated with semen from S males.

Specific features of in vivo and in vitro sperm storage in birds.
E. Blesbois,J. P. Brillard +1 more
TL;DR: This review focuses on some of the main features of sperm selection and storage in birds mainly on the basis of studies performed in poultry species, with emphasis on the initial selection of sperm at the female vagina level prior to migration towards the sperm storage tubules.
