Journal ArticleDOI
Inhibition of Spermatogenesis by Triterpenes of Albizia lebbeck (L.) Benth Pods in Male Albino Rats
TL;DR: Oral administration of triterpenes isolated from Albizia lebbeck pods causes spermatogenesis arrest in male albino rats.
Journal ArticleDOI
Age, photoperiod and estrogen dependent variations in the shell gland and the expression of AVT in the ovary of Japanese quail.
TL;DR: It is concluded that estrogen not only affects the growth and differentiation of ovary and oviduct including shell gland but also regulates the expression of ovarian AVT.
Journal ArticleDOI
Decidua and implantation of the embryo from a historical perspective.
TL;DR: The evolution of the modern concepts of decidualization and embryonic implantation are reviewed, emphasizing how closely interrelated these two processes are.
Journal ArticleDOI
Histological studies on early oogenesis in barfin flounder (Verasper moseri).
TL;DR: The histological changes during early oogenesis in barfin flounder (Verasper moseri) are investigated and it is proposed that the small nuclear cells were in the mitotic prophase of oogonia and the large nuclear cellswere in the meiotic pro phase of oocytes, and that the nuclear size increases upon the initiation of meiosis.
Histological analysis of gonad development in a freshwater shrimp, caridina nilotica (decapoda: atyidae)
TL;DR: An examination of gonad morphology in developing caridina nilitica, with special attention given to the period of sex transition, found that the ovaries consisted of oocytes in the first and second stage of oogenesis.

Seasonal breeding:nature's contraceptive.
G A Lincoln,Roger V. Short +1 more
TL;DR: The seasonal cycle highlights the seasonal changes in daylight length, rutting behavior, testicular diameter, sexual skin flush, and concentrations of plasma follicle-stimulating hormone, prolactin, and testosterone in a group of rams throughout the year.
Journal ArticleDOI
The physiological responses of anovulatory ewes to the introduction of rams: a review.
TL;DR: Ewes of many breeds can be stimulated to ovulate by the reintroduction of rams and appear to be effected both through a delay in the onset of the LH surge and through a direct action of progesterone on the ovary.
Journal ArticleDOI
Factors affecting the secretion of luteinizing hormone in the ewe.
TL;DR: LH is secreted as discrete pulses throughout all stages of the reproductive cycle of the ewe, including pre‐pubertal, seasonal and lactational anoestrus, and the luteal and follicular phases of the oestrous cycle.
Nutritional influences on reproduction in mature male sheep and goats
TL;DR: In this article, it was shown that nutritional signals exert powerful effects on the reproductive system of mature male ruminants, and the responses are partly independent of changes in gonadotrophin secretion.
