Reproduction is the complex set of biological processes that result in the formation of a new organism. It is crucial, especially in our production animals, that we understand how these processes occur normally. Pathology and disease are common within the reproductive system and can not only lead to a sick animal but also lead to loss of production. In this section we hope to cover all the main processes in the domestic animals.  This will lay a foundation to aid in the understanding of more potentially quite complex pathologies.

Reproduction is the complex set of biological processes that result in the formation of a new organism; it is crucial that we understand how these processes occur normally and have a good grasp of the role of [[Reproductive Hormones Overview - Anatomy & Physiology|hormones]] in the reproductive process. Pathology and disease are common within the reproductive system and can not only lead to a sick animal but also to a loss in production. In this section we hope to cover all the main processes in domestic animals, laying a foundation for understanding the associated pathological states.

[[Puberty Defining - Anatomy & Physiology|Puberty]] is the process of aquiring reproductive capability, and age at onset of puberty varies from between [[Puberty Overview - Anatomy & Physiology|species]]. There are several factors involved in triggering the [[Puberty Onset Influencing Factors - Anatomy & Physiology|onset]] of puberty, including body size, nutritional factors, day length, genetic factors and environmental and social factors. The onset depends on the ability of specific hypothalamic neurons to produce [[Puberty Endocrine Events - Anatomy & Physiology|gonadotropin-releasing hormone (GnRH)]] in sufficient quantities to both promote and support gametogenesis. The hypothalamus itself is influenced by hormonal factors that are [[Hypothalamus Differences in the Male and Female - Anatomy & Physiology|male or female specific]].

Female animals regularly enter a phase where they are sexually active and receptive to males; this is known as the [[Oestrous Cycle - Anatomy & Physiology|oestrous cycle]]. Some animals are able to reproduce all year round, but many have an anoestrus phase which requires a [[Seasonality of Reproduction - Anatomy & Physiology|seasonal response]] for cycling to begin. In some species [[Oestrus Behaviour - Anatomy & Physiology|detection of seasonal cycling]] can be crucial to productivity.

Female animals have various [[Reproductive Behaviour Overview - Anatomy & Physiology|behavioural]] and chemical signals which increase their [[Attractivity Behaviour - Anatomy & Physiology|attractiveness]] to males and others which signal their [[Proceptivity Behaviour - Anatomy & Physiology|acceptance]] of attention from the male. Further cues indicate that the female is [[Receptivity Behaviour - Anatomy & Physiology|receptive]] to mating. Other reproductive female behaviours include [[Maternal Behaviour - Anatomy & Physiology|maternal]] and  [[Nursing Behaviour - Anatomy & Physiology|nursing]] behaviour. In  [[Nervous Pathway Eliciting Reproductive Behaviour - Anatomy & Physiology|neurological terms]] sensory information from behavioural and chemical cues are processed by the hypothalamus, which induces the appropriate mating response via specific peptides which activate neurons in the midbrain and brainstem.

Males of different species are often referred to by specific [[Useful Terms for Male Animals - Anatomy & Physiology|names]] which reflect their repoductive status. Males differ from females in the [[Spermatogenesis and Spermiation - Anatomy & Physiology|production of sperm]] which takes place from puberty onwards - unlike females where ova are produced prior to birth. The [[Spermatogenesis and Spermiation - Anatomy & Physiology|hormones]] controlling sperm production, or spermatogenesis are luteinising hormone (LH) and follicle-stimulating hormone (FSH).

The [[Nervous Pathway Eliciting Reproductive Behaviour - Anatomy & Physiology|neurological pathways]] that control reproductive behaviour are similar to the female, but the response is male specific and includes [[Pre-copulatory Behaviour - Anatomy & Physiology|pre-copulatory]], [[Copulatory Behaviour - Anatomy & Physiology|copulatory]] and [[Post-Copulatory Behaviour - Anatomy & Physiology|post-copulatory]] behaviour.

After mating has occured, sperm must [[Sperm in the Female Tract - Anatomy & Physiology|travel]] along the female reproductive tract towards the uterus in order to [[Fertilisation - Anatomy & Physiology|fertilise]] the oocyte. A single spermatazoon penetrates the oocyte and the male and female pronuclei fuse to form an ootid which divides repeatedly to form the [[Blastocyst Embryonic Development - Anatomy & Physiology|blastocyst]]. At this stage the genetic sex of the offspring is determined as male gametes are [[Sexual Differentiation - Anatomy & Physiology|heterogametic]]. The blastocyst continues to divide and grow until the outer layer, the zona pellucida ruptures and the blastocyst 'hatches' and becomes free floating within the uterus. The blastocyt continues to grow and develop until it becomes an embryo with placental and embryonic membranes such as the amniotic sac; the placental membranes then attach to the uterine endometrium in a process known as [[Implantation - Anatomy & Physiology|implantation]]. During embryonic development the process of [[Internal and External Genitalia Development - Anatomy & Physiology|sexual differentiation]] begins.

In most domestic species, pregnancy is maintained by hormonal feedback from the corpus luteum and, in many species, the placenta. The corpus luteum is maintained in early pregnancy and progesterone levels remain elevated as a result. This maintains negative feedback to the hypothalamus and anterior pituitary gland which inhibits further follicular development and ovulation. In polyoestrous species, it prevents the return to oestrus. In many species the [[Placenta Endocrine Function_- Anatomy & Physiology|placenta]] will take over or supplement the corpus luteum as the source of progesterone during pregnancy; the placenta is a source of many of the hormones that  regulate changes during preganancy, stimulating mammary growth, the growth of the myometrium, preparation for parturition, and secreting chorionic gonadotrophin in species where this is required for the [[Maternal Recognition of Pregnancy - Anatomy & Physiology|maternal recognition of pregnancy]]. [[Litter Sizes - Anatomy & Physiology|Litter sizes]] vary between species, as do methods of pregnancy diagnosis.

The process of giving birth, or [[Normal Parturition - Anatomy & Physiology|parturition ]] is conventionally divided into [[Normal Parturition - Anatomy & Physiology|three stages]]; stage one includes the movement of the foetus into the birthing position and preparation of the reproductive tract for birth, which is followed by stage two - contractions and the birth itself. Finally, stage three involves the expulsion of the foetal membranes. The timings of each stage vary from species to species, and a good knowledge of the normal progression of parturition is essential to detect when things are not proceeding normally. There are several [[:Category:Reproductive Disorders|conditions]] that can occur to disturb the normal progress of parturition, including dystocia, uterine inertia, ring womb, prolapses, retained placenta, endometritis and foetal abnormalities. Like pregnancy, parturition is under complex [[Parturition Endocrine Control - Anatomy & Physiology|hormonal control]], and this can be manipulated [[Parturition Pharmacological Manipulation - Anatomy & Physiology|pharmacalogically]] to alter the timing of parturition.

[[Puerperium - Anatomy & Physiology|Puerperium]] describes the period of time immediately following parturition, when the female enters a period of reproductive repair and begins lactation. For a period of time these two processes overlap. During this time the female experiences regular myometrial contractions which expel the remaining fluid and tissues present following birth, allowing the uterus to begin involution and repair so that the reproductive cycle can begin once more. The discharge appears at the vulva and is known as lochia. The process of birth can predispose the reproductive tract to heavy bacterial contamination, but physiological and hormonal changes encourage the removal of bacteria before infection can become established. There are many environmental and management influences that will affect the length of time that puerperium lasts, as well as differences between species.

The secretion of milk from the mammary glands is known as [[Lactation - Anatomy & Physiology|lactation]] - the milk provides [Milk Composition and Biosynthesis- Anatomy & Physiology|nourishment]] for the neonate in addition to immunoprotection in the form of anitibodies which are contained in the initial mammary secretions, or [[Milk_Composition_and_Biosynthesis- Anatomy & Physiology#Colostrum|colostrum]]. Mammary development and milk production and ejection are induced by [[Lactation - Endocrine Control - Anatomy & Physiology|hormonal signals]]. Lactation continues until the neonate is weaned; after weaning the [[Mammary Gland - Anatomy & Physiology|mammary glands]] undergo [[Lactation - Anatomy & Physiology#Involution|involution]] and return to a non-secretory state.

Various pathological states that affect mammary tissues include [[Neoplasia - Pathology#Examples of Tumour Types|mammary neoplasia]] and [[Healing and Repair - Pathology#Female|mastitis]]. Metabolic disturbances can also occur during lactation, the most common being hypocalcaemia or 'milk fever'.

Technologies such as [[Artificial Insemination - Anatomy & Physiology|artificial insemination]] (AI) have been in use for some time and in cattle, for example have become standard practice for reproduction purposes; the technique requires [[Semen Collection - Anatomy & Physiology|collection of semen]] from the male, which is preserved, transported and introduced into the female reporoductive tract in synchrony with her ovulation cycle. Recently other techniques have been developed which permit development of the embryo from a donor animal in a recepient female who will carry the pregnancey to term and nurse the resulting offspring - a technique called [[Embryo Transfer - Anatomy & Physiology|embryo transfer]]. This technique has some unique advantages and is becoming popular, for example in some equine studs where successful mares can continue their competative careers and still become part of a breeding programme.

Introduction to the Reproductive system

Reproduction is the complex set of biological processes that result in the formation of a new organism. It is crucial, especially in our production animals, that we understand how these processes occur normally. Pathology and disease are common within the reproductive system and can not only lead to a sick animal but also lead to loss of production. In this section we hope to cover all the main processes in the domestic animals. This will lay a foundation to aid in the understanding of more potentially quite complex pathologies.

Puberty

Pubertyis the process of aquiring reproductive capability, and age at onset of puberty varies from between species. The onset depends on the ability of specific hypothalamic neurons to produce GnRH in sufficient quantities to both promote and support gametogenesis.
