How Do Hedgehogs Mate? A Step-by-Step Guide to Understanding Hedgehog Mating Behaviors.

Hedgehogs are insectivorous animals that belong to the Erinaceidae family. They are found in various parts of the world, including Europe, Asia, Africa, and New Zealand. Hedgehogs have a unique reproductive system that allows them to breed once a year.

Male hedgehogs are known as boars, while females are known as sows. Hedgehogs reach sexual maturity at around eight months of age. The breeding season for hedgehogs begins in late summer and lasts until early autumn. During this period, male hedgehogs become more active, and their testosterone levels increase, leading to changes in their behavior and physical appearance.

Pre-Mating Behaviors

Mating Season and Hormonal Changes

The hedgehog mating season starts in late summer and ends in early autumn. During this period, male hedgehogs become more vocal, active, and aggressive. Their testosterone levels increase, leading to physiological changes such as an increase in their testes’ size, seminal vesicles, and prostate gland.

Female hedgehogs’ reproductive system also undergoes changes in response to the hormonal changes in males. The female reproductive cycle is triggered by a surge in luteinizing hormone (LH) and follicle-stimulating hormone (FSH). These hormones stimulate the ovaries, leading to the release of eggs from the follicles.

Male Hedgehog Courtship Behaviors

Male hedgehogs exhibit various courtship behaviors to attract female hedgehogs. These behaviors include circling, snorting, and licking. Male hedgehogs also produce a scent from their skin glands, which acts as a pheromone to attract females.

Female Hedgehog Courtship Behaviors

Female hedgehogs are more selective in their choice of mate. They may reject male hedgehogs if they are not interested or if they perceive them as a threat. Female hedgehogs exhibit a range of courtship behaviors, such as lowering their quills, raising their hindquarters, and wiggling their ears.

Mating Behaviors

Mounting and Penetration

Once a female hedgehog has accepted a male hedgehog’s courtship, the mating process begins. Male hedgehogs mount the female hedgehog from behind and attempt to penetrate her reproductive tract. Male hedgehogs have a retractable penis that emerges from their preputial sac during mating. The penis has a hook-like structure that helps to anchor the male hedgehog to the female.

Copulation and Ejaculation

Once the male hedgehog has successfully penetrated the female hedgehog, he begins to copulate. Copulation can last for several minutes, during which time the male hedgehog ejaculates his semen into the female’s reproductive tract.

Multiple Mating and Paternal Uncertainty

Female hedgehogs may mate with multiple male hedgehogs to increase their chances of fertilization. This can lead to paternal uncertainty, as it may be difficult to determine which male hedgehog fathered the offspring.

Post-Mating Behaviors

Post-Copulatory Behavior of Male and Female Hedgehogs

After mating, male and female hedgehogs exhibit different post-copulatory behaviors. Male hedgehogs may continue to pursue female hedgehogs, while female hedgehogs may become aggressive towards male hedgehogs.

Gestation and Pregnancy

Female hedgehogs have a gestation period of around 35 days. During this time, the fertilized eggs develop into embryos and then into hoglets. Female hedgehogs give birth to litters of two to six hoglets, which are born blind and hairless.

Birthing and Raising Hoglets

Female hedgehogs provide maternal care to their hoglets, nursing and protecting them until they are old enough to fend for themselves. Hoglets are weaned at around four to six weeks of age and reach sexual maturity at around six months of age.

Common Mating Problems and Solutions

Infertility and Low Reproductive Success

Hedgehogs can experience infertility or low reproductive success due to various factors, such as age, genetics, or environmental conditions. Breeding programs can help to ensure the genetic diversity and health of hedgehog populations.

Mating Aggression and Injuries

Mating aggression and injuries can occur when male hedgehogs compete for female hedgehogs or when female hedgehogs reject male hedgehogs. Providing adequate space and monitoring mating behaviors can help to prevent aggression and injuries.

Medical Interventions and Breeding Programs

Medical interventions, such as hormone therapy or artificial insemination, can help to overcome reproductive problems in hedgehogs. Breeding programs can also help to ensure the genetic diversity and health of hedgehog populations.


Understanding hedgehog mating behaviors can help hedgehog owners and breeders provide the best care and support for these animals. Hedgehogs exhibit various pre-mating, mating, and post-mating behaviors that are driven by hormonal changes and physical interactions. Additionally, hedgehogs can experience various mating problems that can be addressed through medical interventions and breeding programs. By understanding hedgehog mating behaviors and addressing mating problems, we can help to ensure the health and wellbeing of hedgehogs and support their conservation efforts.
