It is not true that men can ejaculate only once. Immediately after orgasm, both men and women experience what is known as a refractory period, a period during which further stimulation is not effective and is often uncomfortable. After the refractory period, which may last only a few minutes, orgasm and ejaculation can occur again. Naturally, it may take longer to reach a climax, and the volume of the ejaculate may be less than before, but it can definitely still happen. Typically, younger men can climax more times consecutively than older men. For a woman, the ability to have multiple consecutive orgasms tends to be related to how comfortable she is with her body, and typically a woman's body comfort will increase as she ages, so up to a point, an older woman will tend to be more capable of multiple orgasms.
Males don't get periods because they don't go through a menstrual cycle, which is needed for a women to have a baby. Instead, males get the occasional 'wet dream,' in which they ejaculate while they sleep. This happens randomly instead of once a month. Males have testacles which make testosterone and the female organ the uterus and the sides of the uterus are made of blood and the testacles are not made up of blood and when a female has her period the blood from the sides of the uterus shed through the vagina and a male does not have blood shedded because males do not make estrogen. This is why males do not have periods.
Reproduction, including the ability to produce gametes (sperm in males, eggs in females) and engage in sexual activity, is a process that can only be completed once puberty starts.
To answers your question we must first explore the cells involved in fertilization and how they are produced. The male gamete, special cells used to reproduce that contain only 23 chromosomes, are called sperm cells. Sperm cells are produce in a part of the testes that are basically tiny tubes. Males only begin to produce these sperm cells after puberty. This is any where from 10 to 16 years of age for males. Females on the other hand are born with all the eggs cells or ova they will ever have. Like the male's gametes the female's gametes contain only 23 chromosomes. Around the age of 11 to 15 years old females begin to have their period. Most people commonly associate this with the beginning of ovulation, or when females release eggs to be fertilized into the fallopian tubes. However menstruation can be very irregular for the first 6 to 24 months after the first menstrual cycle has occurred. Once both males and females are able to produce mature gametes fertilization can occur. Fertilization occurs after a sperm cell penetrates an ovum and combines with it. This forms a cell that has 46 chromosomes and is known as a zygote. It is important to note that the two cells must combine, not simply sperm egg penetration. Sperm and ova can be combined by traditional means i.e. sexual replication, or alternative means such as in vitro fertilization or intracytoplasmic sperm injection.
Yes, it is possible to get adenovirus more than once because there are multiple strains of the virus and immunity to one strain does not necessarily protect against infection with another strain.
The blood of males is not passed to offspring. Instead, genetic material from the father, including DNA found in sperm, is combined with genetic material from the mother during fertilization to create offspring with a unique genetic makeup. Once the egg is fertilized, it develops into an embryo and ultimately a new individual with its own blood supply.
males can orgasm once or maybe twice a day, females up to 7 or more
Females, by a substantial margin. Few men see a doctor as much as once a year.
Black Mambas breed only once a year. Breeding season is in Spring which is around the month of September. During this period, Males fight for mating rights with females. Males locate suitable females by following a scent trail. Once the copulation is over, males and females go their own seperate ways.
A male has more of a V shaped tail. A female has more of a U or a rounded V and First if your comets are not at least 2 years of age, they won't breed. Males vent openings are concave or sunken in while the females vent opening is convex or poking out. The males have firmer dorsal fins and are more streamline than the females. The females are heavier in the abdomen area than the males. Breeding tubers won't appear on the males gillcovers or fins until spawn. That is to say you don't have two females or two males. They will breed once they are old enough and if they are male and female
During the breeding season (Spring time) the males will nudge the females to try to get a chase going. Once the chase starts, the males chase the females and the excitement grows, the chase gets faster, and the spawning begins.
Platypuses breed just once a year. Males will mate with several females during that time, but females will generally only mate with one male.
Absolutely not. They remain with the pride for years. Males leave sooner than females, and sometimes, females don't leave at all.
A cock bird is usually slightly larger than a hen (depending on the strain of bird). A male will spread it's tail feathers and drag them across the ground/floor when he is chasing after his female to go to nest. Females also spread their tail feathers, but they don't drag the feathers across the floor. Males make a distinctive "cooing" sound (more so than females). When eggs are present, males incubate during the day, females at night (they take 12-hour shifts). Males care for their squeakers once they leave the nest, while the female goes to nest again. Males tend to "defend" their perch space(s) more than females do (females just fly away). The top of a male's head is "flat" whereas a female's is rounded. Females just look more feminine than males do when looking at them as a whole.

There was once a coalition of cheetahs found with two females, three males, and three cubs. It was unkown if the group stayed together. Usually, only males are very social though females do not mind interaction with other cheetahs. There is the misconception that lions are the only social cat, Cheetah males are social and females can join a coalition if they wanted.
Yes, it only happens once for males and females during childhood.
Jaguar Females reach sexual maturity at around 2 years of age and Males after they are 3 years or more. The mate year round and esp. when prey is plentiful. Males locate receptive females using scent markings. After Mating, males go away leaving the female to do all the parenting. Females usually reproduce once every 2-3 years. They are receptive to mating only after their existing litter is old enough to fend for themselves
