Q

whats an estrous cycle

A

Female dogs will have their first estrous (reproductive or heat) cycle when they reach puberty. Each cycle consists of several stages; the stage called estrus refers to when the female can become pregnant. Often, a dog that is in the estrus stage is said to be in heat or season.

Q

Neonate

A

A newborn animal.

27
Q

testes

A

The male reproductive organs responsible for producing sperm and testosterone.

28
Q

semen

A

The fluid containing sperm and various secretions from the male reproductive organs.

29
Q

ovary

A

The female reproductive organ that produces eggs and hormones.

30
Q

follicle

A

A fluid-filled sac on the ovary containing an immature egg (oocyte).

31
Q

ovum

A

A mature egg released from the ovary during ovulation.

32
Q

placenta

A

The organ that provides nutrients and oxygen to the developing fetus and removes waste products.

33
Q

Spermatogenesis

A

The process of sperm production in the testes.

34
Q

Fertilization

A

The union of a sperm cell with an egg cell to form a zygote.

35
Q

Estradiol

A

A female sex hormone involved in the regulation of the estrous cycle.

36
Q

Progesterone

A

A hormone produced by the ovaries that is involved in maintaining pregnancy.

37
Q

Luteinizing hormone

A

Luteinizing hormone (LH): A hormone released by the pituitary gland that triggers ovulation and the formation of the corpus luteum.v

38
Q

Follicle-stimulating hormone (FSH)

A

Follicle-stimulating hormone (FSH): A hormone released by the pituitary gland that stimulates the growth and development of ovarian follicles.

39
Q

Artificial insemination (AI)

A

The process of placing sperm into the reproductive tract of a female animal without natural mating.

40
Q

Pyometra

A

A potentially life-threatening uterine infection characterized by the accumulation of pus in the uterus.

41
Q

A

Difficult or prolonged labor during childbirth.

A

A bacterial infection that can cause reproductive problems, including abortion and infertility, in animals.

43
Q

ovarian cyst

A

A fluid-filled sac on the ovary that may interfere with reproductive function.

44
Q

Parthenogenesis

A

Reproduction that occurs without fertilization, resulting in offspring from a single parent, typically seen in some reptiles and invertebrates.

45
Q

Ectopic pregnancy

A

A pregnancy that occurs outside the uterus, often in the fallopian tube, which can be dangerous for the mother.

Q

Teratogen

A

A substance or agent that can cause birth defects or abnormalities in developing embryos. A teratogen is any substance, organism, physical agent, or environmental factor that can disrupt the normal development of an embryo or fetus, leading to congenital abnormalities or birth defects. These defects can range from minor structural anomalies to severe developmental disabilities, depending on the timing, duration, and intensity of exposure to the teratogenic agent during pregnancy.

51
Q

whats a surrogate mother

A

A surrogate mother, in the context of reproductive medicine, is a woman who carries and gives birth to a child on behalf of another individual or couple. The child may be genetically related to the intended parents or may be conceived using donated gametes (egg or sperm) or embryos. Surrogacy is typically used as an option for individuals or couples who are unable to conceive or carry a pregnancy to term on their own due to medical reasons such as infertility, recurrent miscarriage, or other health conditions.

A

Protrusion of the prepuce (foreskin) in male animals.

57
Q

Anestrus

A

Anestrus is a phase in the estrous cycle of female mammals during which they are not sexually receptive and do not exhibit signs of fertility. It is essentially a period of reproductive inactivity or quiescence. Anestrus occurs between periods of sexual receptivity (estrus) and is characterized by hormonal and physiological changes that prepare the body for the next reproductive cycle.

58
Q

Sertoli cell tumor

A

A type of testicular tumor that can affect hormone production and fertility in males.

59
Q

Estrous synchronization

A

Manipulation of the estrous cycle in multiple females to coordinate breeding or artificial insemination.

60
Q

gonads

A

Gonads are reproductive organs responsible for producing gametes (sex cells) and sex hormones. In mammals, including humans, gonads exist in two primary forms: testes in males and ovaries in females.

61
Q

Vas deferens:

A

A muscular tube that transports mature sperm from the epididymis to the urethra during ejaculation.

62
Q

Seminal vesicles

A

Seminal vesicles: Glandular structures located near the base of the bladder that produce seminal fluid, which nourishes and transports sperm.

63
Q

permatic cord

A

A cord-like structure containing the vas deferens, blood vessels, nerves, and lymphatics that connect the testes to the body.
